The Normandy landings (codenamed Operation Neptune) were the landing operations on 6 June 1944 (termed D-Day) of the Allied invasion of Normandy in Operation Overlord during World War II. The largest seaborne invasion in history, the operation began the liberation of German-occupied northwestern Europe from Nazi control, and contributed to the Allied victory on the Western Front.

Planning for the operation began in 1943. In the months leading up to the invasion, the Allies conducted a substantial military deception, codenamed Operation Bodyguard, to mislead the Germans as to the date and location of the main Allied landings. The weather on D-Day was far from ideal, but postponing would have meant a delay of at least two weeks, as the invasion planners had requirements for the phase of the moon, the tides, and the time of day that meant only a few days in each month were deemed suitable. Hitler placed German Field Marshal Erwin Rommel in command of German forces and of developing fortifications along the Atlantic Wall in anticipation of an Allied invasion.

The amphibious landings were preceded by extensive aerial and naval bombardment and an airborne assault—the landing of 24,000 British, US, and Canadian airborne troops shortly after midnight. Allied infantry and armoured divisions began landing on the coast of France at 06:30. The target 50-mile (80 km) stretch of the Normandy coast was divided into five sectors: Utah, Omaha, Gold, Juno, and Sword Beach. Strong winds blew the landing craft east of their intended positions, particularly at Utah and Omaha. The men landed under heavy fire from gun emplacements overlooking the beaches, and the shore was mined and covered with obstacles such as wooden stakes, metal tripods, and barbed wire, making the work of the beach clearing teams difficult and dangerous. Casualties were heaviest at Omaha, with its high cliffs. At Gold, Juno, and Sword, several fortified towns were cleared in house-to-house fighting, and two major gun emplacements at Gold were disabled using specialised tanks.

The Allies failed to achieve all of their goals on the first day. Carentan, St. Lô, and Bayeux remained in German hands, and Caen, a major objective, was not captured until 21 July. Only two of the beaches (Juno and Gold) were linked on the first day, and all five bridgeheads were not connected until 12 June. However, the operation gained a foothold that the Allies gradually expanded over the coming months. German casualties on D-Day were around 1,000 men. Allied casualties were at least 10,000, with 4,414 confirmed dead. Museums, memorials, and war cemeteries in the area host many visitors each year.

Background

Between 27 May and 4 June 1940, over 338,000 troops of the British Expeditionary Force and the French Army, trapped along the northern coast of France, were evacuated in the Dunkirk evacuation.[12] After the Germans invaded the Soviet Union in June 1941, Soviet leader Joseph Stalin began pressing for the creation of a second front in western Europe.[13] In late May 1942 the Soviet Union and United States made a joint announcement that a “… full understanding was reached with regard to the urgent tasks of creating a second front in Europe in 1942.”[14] However, Churchill persuaded Roosevelt to postpone the promised invasion as, even with American help, the Allies did not have adequate forces for such a strike.[15]

Instead of an immediate return to France, the Western Allies staged offensives in the Mediterranean Theater of Operations, where British troops were already stationed. By mid-1943, the North African Campaign had been won. The Allies then launched the invasion of Sicily in July 1943, and Italy in September 1943. By then, Soviet forces were on the offensive and had won a major victory at the Battle of Stalingrad. The decision to undertake a cross-channel invasion within the next year was taken at the Trident Conference in Washington in May 1943.[16] Initial planning was constrained by the number of available landing craft, most of which were already committed in the Mediterranean and Pacific.[17] At the Tehran Conference in November 1943, Roosevelt and Churchill promised Stalin that they would open the long-delayed second front in May 1944.[18]

Four sites were considered for the landings: Brittany, the Cotentin Peninsula, Normandy, and Pas de Calais. As Brittany and Cotentin are peninsulas, it would have been possible for the Germans to cut off the Allied advance at a relatively narrow isthmus, so these sites were rejected.[19] As the Pas de Calais is the closest point in continental Europe to Britain, the Germans considered it to be the most likely initial landing zone, so it was the most heavily fortified region.[20] But it offered few opportunities for expansion, as the area is bounded by numerous rivers and canals,[21] whereas landings on a broad front in Normandy would permit simultaneous threats against the port of Cherbourg, coastal ports further west in Brittany, and an overland attack towards Paris and eventually into Germany. Normandy was hence chosen as the landing site.[22] The most serious drawback of the Normandy coast—the lack of port facilities—would be overcome through the development of artificial Mulberry harbours.[23] A series of specialised tanks, nicknamed Hobart’s Funnies, were created to deal with conditions expected during the Normandy campaign, such as scaling sea walls and providing close support on the beach.[24]

The Allies planned to launch the invasion on 1 May 1944.[21] The initial draft of the plan was accepted at the Quebec Conference in August 1943. General Dwight D. Eisenhower was appointed commander of Supreme Headquarters Allied Expeditionary Force (SHAEF).[25] General Bernard Montgomery was named as commander of the 21st Army Group, which comprised all of the land forces involved in the invasion.[26] On 31 December 1943, Eisenhower and Montgomery first saw the plan, which proposed amphibious landings by three divisions with two more divisions in support. The two generals immediately insisted that the scale of the initial invasion be expanded to five divisions, with airborne descents by three additional divisions, to allow operations on a wider front and speed up the capture of the port at Cherbourg.[27] The need to acquire or produce extra landing craft for the expanded operation meant that the invasion had to be delayed to June.[27] Eventually, thirty-nine Allied divisions would be committed to the Battle of Normandy: twenty-two American, twelve British, three Canadian, one Polish, and one French, totalling over a million troops[28] all under overall British command.[29]

Operations

Operation Overlord was the name assigned to the establishment of a large-scale lodgement on the Continent. The first phase, the amphibious invasion and establishment of a secure foothold, was codenamed Operation Neptune.[23] To gain the air superiority needed to ensure a successful invasion, the Allies undertook a bombing campaign (codenamed Operation Pointblank) that targeted German aircraft production, fuel supplies, and airfields.[23] Elaborate deceptions, codenamed Operation Bodyguard, were undertaken in the months leading up to the invasion to prevent the Germans from learning the timing and location of the invasion.[30]

The landings were to be preceded by airborne landings near Caen on the eastern flank to secure the Orne River bridges and north of Carentan on the western flank. The Americans, assigned to land at Utah Beach and Omaha Beach, were to attempt to capture Carentan and St. Lô the first day, then cut off the Cotentin Peninsula and eventually capture the port facilities at Cherbourg. The British at Sword Beach and Gold Beach and Canadians at Juno Beach would protect the American flank and attempt to establish airfields near Caen. A secure lodgement would be established and an attempt made to hold all territory north of the AvranchesFalaise line within the first three weeks.[31][32] Montgomery envisaged a ninety-day battle, lasting until all Allied forces reached the Seine.[33]

Deception plans

Shoulder patches were designed for units of the fictitious First United States Army Group under Patton.

Under the overall umbrella of Operation Bodyguard, the Allies conducted several subsidiary operations designed to mislead the Germans as to the date and location of the Allied landings.[34] Operation Fortitude included Fortitude North, a misinformation campaign using fake radio traffic to lead the Germans into expecting an attack on Norway,[35] and Fortitude South, a major deception involving the creation of a fictitious First United States Army Group under Lieutenant General George S. Patton, supposedly located in Kent and Sussex. Fortitude South was intended to deceive the Germans into believing that the main attack would take place at Calais.[30][36] Genuine radio messages from 21st Army Group were first routed to Kent via landline and then broadcast, to give Germans the impression that most of the Allied troops were stationed there.[37] Patton was stationed in England until 6 July, thus continuing to deceive the Germans into believing a second attack would take place at Calais.[38]

Many of the German radar stations on the French coast were destroyed in preparation for the landings.[39] In addition, on the night before the invasion, a small group of Special Air Service (SAS) operators deployed dummy paratroopers over Le Havre and Isigny. These dummies led the Germans to believe that an additional airborne landing had occurred. On that same night, in Operation Taxable, No. 617 Squadron RAF dropped strips of “window”, metal foil that caused a radar return which was mistakenly interpreted by German radar operators as a naval convoy near Le Havre. The illusion was bolstered by a group of small craft towing barrage balloons. A similar deception was undertaken near Boulogne-sur-Mer in the Pas de Calais area by No. 218 Squadron RAF in Operation Glimmer.[40][2]

Weather

The invasion planners determined a set of conditions involving the phase of the moon, the tides, and the time of day that would be satisfied on only a few days in each month. A full moon was desirable, as it would provide illumination for aircraft pilots and have the highest tides. The Allies wanted to schedule the landings for shortly before dawn, midway between low and high tide, with the tide coming in. This would improve the visibility of obstacles on the beach, while minimising the amount of time the men would be exposed in the open.[41] Eisenhower had tentatively selected 5 June as the date for the assault. However, on 4 June, conditions were unsuitable for a landing: high winds and heavy seas made it impossible to launch landing craft, and low clouds would prevent aircraft from finding their targets.[42]

Group Captain James Stagg of the Royal Air Force (RAF) met Eisenhower on the evening of 4 June. He and his meteorological team predicted that the weather would improve enough for the invasion to proceed on 6 June.[43] The next available dates with the required tidal conditions (but without the desirable full moon) would be two weeks later, from 18 to 20 June. Postponement of the invasion would have required recalling men and ships already in position to cross the Channel, and would have increased the chance that the invasion plans would be detected.[44] After much discussion with the other senior commanders, Eisenhower decided that the invasion should go ahead on the 6th.[45] A major storm battered the Normandy coast from 19 to 22 June, which would have made the beach landings impossible.[42]

Allied control of the Atlantic meant German meteorologists had less information than the Allies on incoming weather patterns.[39] As the Luftwaffe meteorological centre in Paris was predicting two weeks of stormy weather, many Wehrmacht commanders left their posts to attend war games in Rennes, and men in many units were given leave.[46] Field Marshal Erwin Rommel returned to Germany for his wife’s birthday and to meet Hitler to try to obtain more Panzers.[47]

German order of battle

Nazi Germany had at its disposal fifty divisions in France and the Low Countries, with another eighteen stationed in Denmark and Norway. Fifteen divisions were in the process of formation in Germany.[48] Combat losses throughout the war, particularly on the Eastern Front, meant that the Germans no longer had a pool of able young men from which to draw. German soldiers were now on average six years older than their Allied counterparts. Many in the Normandy area were Ostlegionen (eastern legions) – conscripts and volunteers from Russia, Mongolia, and elsewhere. They were provided mainly with unreliable captured equipment and lacked motorised transport.[49] Many German units were under strength.[50]

Alarmed by the raids on St Nazaire and Dieppe in 1942, Hitler had ordered the construction of fortifications all along the Atlantic coast, from Spain to Norway, to protect against an expected Allied invasion. He envisioned 15,000 emplacements manned by 300,000 troops, but shortages, particularly of concrete and manpower, meant that most of the strongpoints were never built.[59] As it was expected to be the site of the invasion, the Pas de Calais was heavily defended.[59] In the Normandy area, the best fortifications were concentrated at the port facilities at Cherbourg and Saint-Malo.[27] Rommel was assigned to oversee the construction of further fortifications along the expected invasion front, which stretched from the Netherlands to Cherbourg,[59][60] and was given command of the newly re-formed Army Group B, which included the 7th Army, the 15th Army, and the forces guarding the Netherlands. Reserves for this group included the 2nd, 21st, and 116th Panzer divisions.[61][62]

Rommel believed that the Normandy coast could be a possible landing point for the invasion, so he ordered the construction of extensive defensive works along that shore. In addition to concrete gun emplacements at strategic points along the coast, he ordered wooden stakes, metal tripods, mines, and large anti-tank obstacles to be placed on the beaches to delay the approach of landing craft and impede the movement of tanks.[63] Expecting the Allies to land at high tide so that the infantry would spend less time exposed on the beach, he ordered many of these obstacles to be placed at the high water mark.[41] Tangles of barbed wire, booby traps, and the removal of ground cover made the approach hazardous for infantry.[63] On Rommel’s order, the number of mines along the coast was tripled.[27] The Allied air offensive over Germany had crippled the Luftwaffe and established air supremacy over western Europe, so Rommel knew he could not expect effective air support.[64] The Luftwaffe could muster only 815 aircraft[65] over Normandy in comparison to the Allies’ 9,543.[66] Rommel arranged for booby-trapped stakes known as Rommelspargel (Rommel’s asparagus) to be installed in meadows and fields to deter airborne landings.[27]

Armoured reserves

Rommel believed that Germany’s best chance was to stop the invasion at the shore. He requested that the mobile reserves, especially tanks, be stationed as close to the coast as possible. Rundstedt, Geyr, and other senior commanders objected. They believed that the invasion could not be stopped on the beaches. Geyr argued for a conventional doctrine: keeping the Panzer formations concentrated in a central position around Paris and Rouen and deploying them only when the main Allied beachhead had been identified. He also noted that, in the Italian Campaign, the armoured units stationed near the coast had been damaged by naval bombardment. Rommel’s opinion was that, because of Allied air supremacy, the large-scale movement of tanks would not be possible once the invasion was under way. Hitler made the final decision, which was to leave three Panzer divisions under Geyr’s command and give Rommel operational control of three more as reserves. Hitler took personal control of four divisions as strategic reserves, not to be used without his direct orders.[67][68][69]

Overall, the Second Army contingent consisted of 83,115 men, 61,715 of them British.[11] The nominally British air and naval support units included a large number of personnel from Allied nations, including several RAF squadrons manned almost exclusively by overseas air crew. For example, the Australian contribution to the operation included a regular Royal Australian Air Force (RAAF) squadron, nine Article XV squadrons, and hundreds of personnel posted to RAF units and RN warships.[74] The RAF supplied two-thirds of the aircraft involved in the invasion.[75]

Coordination with the French Resistance

French Resistance members and Allied paratroopers discuss the situation during the Battle of Normandy in 1944

Through the London-based État-major des Forces Françaises de l’Intérieur (French Forces of the Interior), the British Special Operations Executive orchestrated a massive campaign of sabotage to be implemented by the French Resistance. The Allies developed four plans for the Resistance to execute on D-Day and the following days:

  • Plan Vert was a 15-day operation to sabotage the rail system.
  • Plan Bleu dealt with destroying electrical facilities.
  • Plan Tortue was a delaying operation aimed at the enemy forces that would potentially reinforce Axis forces at Normandy.
  • Plan Violet dealt with cutting underground telephone and teleprinter cables.[80]

The resistance was alerted to carry out these tasks by messages personnels transmitted by the BBC’s French service from London. Several hundred of these messages, which might be snatches of poetry, quotations from literature, or random sentences, were regularly transmitted, masking the few that were actually significant. In the weeks preceding the landings, lists of messages and their meanings were distributed to resistance groups.[81] An increase in radio activity on 5 June was correctly interpreted by German intelligence to mean that an invasion was imminent or underway. However, because of the barrage of previous false warnings and misinformation, most units ignored the warning.[82][83]

A 1965 report from the Counter-insurgency Information Analysis Center details the results of the French Resistance’s sabotage efforts: “In the southeast, 52 locomotives were destroyed on 6 June and the railway line cut in more than 500 places. Normandy was isolated as of 7 June.”[84]

Naval activity

Large landing craft convoy crosses the English Channel on 6 June 1944.

Naval operations for the invasion were described by historian Correlli Barnett as a “never surpassed masterpiece of planning”.[85] In overall command was British Admiral Sir Bertram Ramsay, who had served as Flag officer at Dover during the Dunkirk evacuation four years earlier. He had also been responsible for the naval planning of the invasion of North Africa in 1942, and one of the two fleets carrying troops for the invasion of Sicily the following year.[86]

The invasion fleet was drawn from eight different navies, comprising 6,939 vessels: 1,213 warships, 4,126 landing craft of various types, 736 ancillary craft, and 864 merchant vessels.[11] The majority of the fleet was supplied by the UK and Canada, who provided 892 warships and 3,261 landing craft.[75] There were 195,700 naval personnel involved.[11] The invasion fleet was split into the Western Naval Task Force (under Admiral Alan G Kirk) supporting the American sectors and the Eastern Naval Task Force (under Admiral Sir Philip Vian) in the British and Canadian sectors.[87][86] Available to the fleet were five battleships, twenty cruisers, sixty-five destroyers, and two monitors.[88] German ships in the area on D-Day included three torpedo boats, twenty-nine fast attack craft, thirty-six R boats, and thirty-six minesweepers and patrol boats.[89] The Germans also had several U-boats available, and all the approaches had been heavily mined.[41]

Naval losses

At 05:10, four German torpedo boats reached the Eastern Task Force and launched fifteen torpedoes, sinking the Norwegian destroyer HNoMS Svenner off Sword beach but missing the battleships HMS Warspite and Ramillies. After firing, the German vessels turned away and fled east into a smoke screen that had been laid by the RAF to shield the fleet from the long-range battery at Le Havre.[90] Allied losses to mines included USS Corry off Utah and USS PC-1261, a 173-foot patrol craft.[91] In addition, many landing craft were lost.[92]

Bombing

Main article: Bombing of Normandy

Map of the invasion area showing channels cleared of mines, location of vessels engaged in bombardment, and targets on shore

Bombing of Normandy began around midnight with over 2,200 British and American bombers attacking targets along the coast and further inland.[41] The coastal bombing attack was largely ineffective at Omaha, because low cloud cover made the assigned targets difficult to see. Concerned about inflicting casualties on their own troops, many bombers delayed their attacks too long and failed to hit the beach defences.[93] The Germans had 570 aircraft stationed in Normandy and the Low Countries on D-Day, and another 964 in Germany.[41]

Minesweepers began clearing channels for the invasion fleet shortly after midnight and finished just after dawn without encountering the enemy.[94] The Western Task Force included the battleships Arkansas, Nevada, and Texas, plus eight cruisers, twenty-eight destroyers, and one monitor.[95] The Eastern Task Force included the battleships HMS Ramillies and Warspite and the monitor HMS Roberts, twelve cruisers, and thirty-seven destroyers.[6] Naval bombardment of areas behind the beach commenced at 05:45, while it was still dark, with the gunners switching to pre-assigned targets on the beach as soon as it was light enough to see, at 05:50.[96] Since troops were scheduled to land at Utah and Omaha starting at 06:30 (an hour earlier than the British beaches), these areas received only about 40 minutes of naval bombardment before the assault troops began to land on the shore.[97] Some of the landing craft had been modified to provide close support fire, and self-propelled amphibious Duplex-Drive tanks (DD tanks), specially designed for the Normandy landings, were to land shortly before the infantry to provide covering fire. However, few arrived in advance of the infantry, and many sank before reaching the shore, especially at Omaha.[98][99]

The landings

Airborne operations

The success of the amphibious landings depended on the establishment of a secure lodgement from which to expand the beachhead to allow the buildup of a well-supplied force capable of breaking out. The amphibious forces were especially vulnerable to strong enemy counter-attacks before the buildup of sufficient forces in the beachhead could be accomplished. To slow or eliminate the enemy’s ability to organise and launch counter-attacks during this critical period, airborne operations were used to seize key objectives such as bridges, road crossings, and terrain features, particularly on the eastern and western flanks of the landing areas. The airborne landings some distance behind the beaches were also intended to ease the egress of the amphibious forces off the beaches, and in some cases to neutralise German coastal defence batteries and more quickly expand the area of the beachhead.[100][101]

The US 82nd and 101st Airborne Divisions were assigned to objectives west of Utah Beach, where they hoped to capture and control the few narrow causeways through terrain that had been intentionally flooded by the Germans. Reports from Allied intelligence in mid-May of the arrival of the German 91st Infantry Division meant the intended drop zones had to be shifted eastward and to the south.[102] The British 6th Airborne Division, on the eastern flank, was assigned to capture intact the bridges over the Caen Canal and River Orne, destroy five bridges over the Dives 6 miles (9.7 km) to the east, and destroy the Merville Gun Battery overlooking Sword Beach.[103] Free French paratroopers from the British SAS Brigade were assigned to objectives in Brittany from 5 June through August in Operations Dingson, Samwest, and Cooney.[104][105]

BBC war correspondent Robert Barr described the scene as paratroopers prepared to board their aircraft:

Their faces were darkened with cocoa; sheathed knives were strapped to their ankles; tommy guns strapped to their waists; bandoliers and hand grenades, coils of rope, pick handles, spades, rubber dinghies hung around them, and a few personal oddments, like the lad who was taking a newspaper to read on the plane … There was an easy familiar touch about the way they were getting ready, as though they had done it often before. Well, yes, they had kitted up and climbed aboard often just like this – twenty, thirty, forty times some of them, but it had never been quite like this before. This was the first combat jump for every one of them.[106]

American airborne landings

Gliders are delivered to the Cotentin Peninsula by Douglas C-47 Skytrains. 6 June 1944.

The American airborne landings began with the arrival of pathfinders at 00:15. Navigation was difficult because of a bank of thick cloud, and as a result only one of the five paratrooper drop zones was accurately marked with radar signals and Aldis lamps.[107] Paratroopers of the US 82nd and 101st Airborne Divisions, numbering over 13,000 men, were delivered by Douglas C-47 Skytrains of the IX Troop Carrier Command.[108] To avoid flying over the invasion fleet, the planes arrived from the west over the Cotentin Peninsula and exited over Utah Beach.[109][107]

Paratroops from 101st Airborne were dropped beginning around 01:30, tasked with controlling the causeways behind Utah Beach and destroying road and rail bridges over the Douve River.[110] The C-47s could not fly in a tight formation because of thick cloud cover, and many paratroopers were dropped far from their intended landing zones. Many planes came in so low that they were under fire from both flak and machine gun fire. Some paratroopers were killed on impact when their parachutes did not have time to open, and others drowned in the flooded fields.[111] Gathering together into fighting units was made difficult by a shortage of radios and by the bocage terrain, with its hedgerows, stone walls, and marshes.[112][113] Some units did not arrive at their targets until afternoon, by which time several of the causeways had already been cleared by members of the 4th Infantry Division moving up from the beach.[114]

Troops of the 82nd Airborne began arriving around 02:30, with the primary objective of capturing two bridges over the River Merderet and destroying two bridges over the Douve.[110] On the east side of the river, 75 per cent of the paratroopers landed in or near their drop zone, and within two hours they captured the important crossroads at Sainte-Mère-Église (the first town liberated in the invasion[115]) and began working to protect the western flank.[116] Because of the failure of the pathfinders to accurately mark their drop zone, the two regiments dropped on the west side of the Merderet were extremely scattered, with only four per cent landing in the target area.[116] Many landed in nearby swamps, with much loss of life.[117] Paratroopers consolidated into small groups, usually a combination of men of various ranks from different units, and attempted to concentrate on nearby objectives.[118] They captured but failed to hold the Merderet River bridge at La Fière, and fighting for the crossing continued for several days.[119]

Reinforcements arrived by glider around 04:00 (Mission Chicago and Mission Detroit), and 21:00 (Mission Keokuk and Mission Elmira), bringing additional troops and heavy equipment. Like the paratroopers, many landed far from their drop zones.[120] Even those that landed on target experienced difficulty, with heavy cargo such as Jeeps shifting during landing, crashing through the wooden fuselage, and in some cases crushing personnel on board.[121]

After 24 hours, only 2,500 men of the 101st and 2,000 of the 82nd Airborne were under the control of their divisions, approximately a third of the force dropped. This wide dispersal had the effect of confusing the Germans and fragmenting their response.[122] The 7th Army received notification of the parachute drops at 01:20, but Rundstedt did not initially believe that a major invasion was underway. The destruction of radar stations along the Normandy coast in the week before the invasion meant that the Germans did not detect the approaching fleet until 02:00.[123]

British and Canadian airborne landings

The first Allied action of D-Day was Operation Deadstick, a glider assault at 00:16 at Pegasus Bridge over the Caen Canal and the bridge (since renamed Horsa Bridge) over the Orne, half a mile (800 metres) to the east. Both bridges were quickly captured intact, with light casualties, by members of the 5th Parachute Brigade and the 7th (Light Infantry) Parachute Battalion.[124][125] The five bridges over the Dives were destroyed with minimal difficulty by the 3rd Parachute Brigade.[126][127] Meanwhile, the pathfinders tasked with setting up radar beacons and lights for further paratroopers (scheduled to begin arriving at 00:50 to clear the landing zone north of Ranville) were blown off course, and had to set up the navigation aids too far east. Many paratroopers, also blown too far east, landed far from their intended drop zones; some took hours or even days to be reunited with their units.[128][129] Major General Richard Gale arrived in the third wave of gliders at 03:30, along with equipment, such as antitank guns and jeeps, and more troops to help secure the area from counter-attacks, which were initially staged only by troops in the immediate vicinity of the landings.[130] At 02:00, the commander of the German 716th Infantry Division ordered Feuchtinger to move his 21st Panzer Division into position to counter-attack. However, as the division was part of the armoured reserve, Feuchtinger was obliged to seek clearance from OKW before he could commit his formation.[131] Feuchtinger did not receive orders until nearly 09:00, but in the meantime on his own initiative he put together a battle group (including tanks) to fight the British forces east of the Orne.[132]

Only 160 men out of the 600 members of the 9th Battalion tasked with eliminating the enemy battery at Merville arrived at the rendezvous point. Lieutenant Colonel Terence Otway, in charge of the operation, decided to proceed regardless, as the emplacement had to be destroyed by 06:00 to prevent it firing on the invasion fleet and the troops arriving on Sword Beach. In the Battle of Merville Gun Battery, Allied forces disabled the guns at a cost of 75 casualties. The emplacement was found to contain 75 mm guns rather than the expected 150 mm heavy coastal artillery.[133]

With this action, the last of the D-Day goals of the British 6th Airborne Division was achieved.[134] They were reinforced at 12:00 by commandos of the 1st Special Service Brigade, who landed on Sword Beach, and by the 6th Airlanding Brigade, who arrived in gliders at 21:00 in Operation Mallard.[135]

Utah Beach

Utah Beach was in the area defended by two battalions of the 919th Grenadier Regiment.[136] Members of the 8th Infantry Regiment of the 4th Infantry Division were the first to land, arriving at 06:30. Their landing craft were pushed to the south by strong currents, and they found themselves about 2,000 yards (1.8 km) from their intended landing zone. This site turned out to be better, as there was only one strongpoint nearby rather than two, and bombers of IX Bomber Command had bombed the defences from lower than their prescribed altitude, inflicting considerable damage. In addition, the strong currents had washed ashore many of the underwater obstacles. The assistant commander of the 4th Infantry Division, Brigadier General Theodore Roosevelt, Jr., the first senior officer ashore, made the decision to “start the war from right here”, and ordered further landings to be re-routed.[137][138]

The initial assault battalions were quickly followed by 28 DD tanks and several waves of engineer and demolition teams to remove beach obstacles and clear the area directly behind the beach of obstacles and mines. Gaps were blown in the sea wall to allow quicker access for troops and tanks. Combat teams began to exit the beach at around 09:00, with some infantry wading through the flooded fields rather than travelling on the single road. They skirmished throughout the day with elements of the 919th Grenadier Regiment, who were armed with antitank guns and rifles. The main strongpoint in the area and another 1,300 yards (1.2 km) to the south were disabled by noon.[139] The 4th Infantry Division did not meet all of their D-Day objectives at Utah Beach, partly because they had arrived too far to the south, but they landed 21,000 troops at the cost of only 197 casualties.[140][141]

Pointe du Hoc

Rangers scaling the wall at Pointe du Hoc.

Pointe du Hoc, a prominent headland situated between Utah and Omaha, was assigned to two hundred men of 2nd Ranger Battalion, commanded by Lieutenant Colonel James Rudder. Their task was to scale the 30-metre (98 ft) cliffs with grappling hooks, ropes, and ladders to destroy the coastal gun battery located at the top. The cliffs were defended by the German 352nd Infantry Division and French collaborators firing from above.[142] Allied destroyers Satterlee and Talybont provided fire support. After scaling the cliffs, the Rangers discovered that the guns had already been withdrawn. They located the weapons, unguarded but ready to use, in an orchard some 550 metres (600 yd) south of the point, and disabled them with explosives.[142]

The now-isolated Rangers fended off numerous counter-attacks from the German 914th Grenadier Regiment. The men at the point became isolated and some were captured. By dawn on D+1, Rudder had only 90 men able to fight. Relief did not arrive until D+2, when members of the 743rd Tank Battalion and others arrived.[143][144] By then, Rudder’s men had run out of ammunition and were using captured German weapons. Several men were killed as a result, because the German weapons made a distinctive noise, and the men were mistaken for the enemy.[145] By the end of the battle, the Rangers casualties were 135 dead and wounded, while German casualties were 50 killed and 40 captured. An unknown number of French collaborators were executed.[146][147]

Omaha Beach

Omaha, the most heavily defended beach, was assigned to the 1st Infantry Division and 29th Infantry Division.[148] They faced the 352nd Infantry Division rather than the expected single regiment.[149] Strong currents forced many landing craft east of their intended position or caused them to be delayed.[150] For fear of hitting the landing craft, American bombers delayed releasing their loads and, as a result, most of the beach obstacles at Omaha remained undamaged when the men came ashore.[151] Many of the landing craft ran aground on sandbars and the men had to wade 50 to 100 yards (46 to 91 m) in water up to their necks while under fire to get to the beach.[99] In spite of the rough seas, DD tanks of two companies of the 741st Tank Battalion were dropped 5,000 yards (4,600 m) from shore, and 27 of the 32 flooded and sank, with the loss of 33 crew.[152] Some tanks, disabled on the beach, continued to provide covering fire until their ammunition ran out or they were swamped by the rising tide.[153]

Casualties were around 2,000, as the men were subjected to fire from the cliffs above.[154] Problems clearing the beach of obstructions led to the beachmaster calling a halt to further landings of vehicles at 08:30. A group of destroyers arrived around this time to provide fire support so landings could resume.[155] Exit from the beach was possible only via five heavily defended gullies, and by late morning barely 600 men had reached the higher ground.[156] By noon, as the artillery fire took its toll and the Germans started to run out of ammunition, the Americans were able to clear some lanes on the beaches. They also started clearing the gullies of enemy defences so that vehicles could move off the beach.[156] The tenuous beachhead was expanded over the following days, and the D-Day objectives for Omaha were accomplished by D+3.[157]

Gold Beach

Main article: Gold Beach

British troops come ashore at Jig Green sector, Gold Beach.

At Gold, high winds made conditions difficult for the landing craft, and the amphibious DD tanks were released close to shore or directly on the beach instead of further out as planned.[158] Three of the four guns in a large emplacement at the Longues-sur-Mer battery were disabled by direct hits from the cruisers Ajax and Argonaut at 06:20. The fourth gun resumed firing intermittently in the afternoon, and its garrison surrendered on 7 June.[159] Aerial attacks had failed to hit the Le Hamel strongpoint, which had its embrasure facing east to provide enfilade fire along the beach and had a thick concrete wall on the seaward side.[160] Its 75 mm gun continued to do damage until 16:00, when a modified Armoured Vehicle Royal Engineers (AVRE) tank fired a large petard charge into its rear entrance.[161][162] A second casemated emplacement at La Rivière containing an 88 mm gun was neutralised by a tank at 07:30.[163]

Meanwhile, infantry began clearing the heavily fortified houses along the shore and advanced on targets further inland.[164] The No. 47 (Royal Marine) Commando moved toward the small port at Port-en-Bessin and captured it the following day in the Battle of Port-en-Bessin.[165] Company Sergeant Major Stanley Hollis received the only Victoria Cross awarded on D-Day for his actions while attacking two pillboxes at the Mont Fleury high point.[166] On the western flank, the 1st Battalion, Hampshire Regiment captured Arromanches (future site of Mulberry “B”), and contact was made on the eastern flank with the Canadian forces at Juno.[167] Bayeux was not captured the first day due to stiff resistance from the 352nd Infantry Division.[164] Allied casualties at Gold Beach are estimated at 1,000.[11]

Juno Beach

Main article: Juno Beach

Personnel of Royal Canadian Navy Beach Commando “W” land on Mike Beach sector of Juno Beach, 6 June 1944.

The landing at Juno was delayed because of choppy seas, and the men arrived ahead of their supporting armour, suffering many casualties while disembarking. Most of the offshore bombardment had missed the German defences.[168] Several exits from the beach were created, but not without difficulty. At Mike Beach on the western flank, a large crater was filled using an abandoned AVRE tank and several rolls of fascine, which were then covered by a temporary bridge. The tank remained in place until 1972, when it was removed and restored by members of the Royal Engineers.[169] The beach and nearby streets were clogged with traffic for most of the day, making it difficult to move inland.[92]

Major German strongpoints with 75 mm guns, machine-gun nests, concrete fortifications, barbed wire, and mines were located at Courseulles-sur-Mer, St Aubin-sur-Mer, and Bernières-sur-Mer.[170] The towns themselves also had to be cleared in house-to-house fighting.[171] Soldiers on their way to Bény-sur-Mer, 3 miles (5 km) inland, discovered that the road was well covered by machine gun emplacements that had to be outflanked before the advance could proceed.[172] Elements of the 9th Canadian Infantry Brigade advanced to within sight of the Carpiquet airfield late in the afternoon, but by this time their supporting armour was low on ammunition so the Canadians dug in for the night. The airfield was not captured until a month later as the area became the scene of fierce fighting.[173] By nightfall, the contiguous Juno and Gold beachheads covered an area 12 miles (19 km) wide and 7 miles (10 km) deep.[174] Casualties at Juno were 961 men.[175]

Sword Beach

Main article: Sword Beach

British troops take cover after landing on Sword Beach.

On Sword, 21 of 25 DD tanks of the first wave made it safely ashore to provide cover for the infantry, who began disembarking at 07:30.[176] The beach was heavily mined and peppered with obstacles, making the work of the beach clearing teams difficult and dangerous.[177] In the windy conditions, the tide came in more quickly than expected, so manoeuvring the armour was difficult. The beach quickly became congested.[178] Brigadier Simon Fraser, 15th Lord Lovat and his 1st Special Service Brigade arrived in the second wave, piped ashore by Private Bill Millin, Lovat’s personal piper.[179] Members of No. 4 Commando moved through Ouistreham to attack from the rear a German gun battery on the shore. A concrete observation and control tower at this emplacement had to be bypassed and was not captured until several days later.[180] French forces under Commander Philippe Kieffer (the first French soldiers to arrive in Normandy) attacked and cleared the heavily fortified strongpoint at the casino at Riva Bella, with the aid of one of the DD tanks.[180]

The ‘Morris’ strongpoint near Colleville-sur-Mer was captured after about an hour of fighting.[178] The nearby ‘Hillman’ strongpoint, headquarters of the 736th Infantry Regiment, was a large complex defensive work that had come through the morning’s bombardment essentially undamaged. It was not captured until 20:15.[181] The 2nd Battalion, King’s Shropshire Light Infantry began advancing to Caen on foot, coming within a few kilometres of the town, but had to withdraw due to lack of armour support.[182] At 16:00, the 21st Panzer Division mounted a counter-attack between Sword and Juno and nearly succeeded in reaching the Channel. It met stiff resistance from the British 3rd Division and was soon recalled to assist in the area between Caen and Bayeux.[183][184] Estimates of Allied casualties on Sword Beach are as high as 1,000.[11]

Analysis

Situation map for 24:00, 6 June 1944

The Normandy landings were the largest seaborne invasion in history, with nearly 5,000 landing and assault craft, 289 escort vessels, and 277 minesweepers participating.[185] Nearly 160,000 troops crossed the English Channel on D-Day,[29] with 875,000 men disembarking by the end of June.[186] Allied casualties on the first day were at least 10,000, with 4,414 confirmed dead.[187] The Germans lost 1,000 men.[188] The Allied invasion plans had called for the capture of Carentan, St. Lô, Caen, and Bayeux on the first day, with all the beaches (other than Utah) linked with a front line 10 to 16 kilometres (6 to 10 mi) from the beaches; none of these objectives were achieved.[32] The five bridgeheads were not connected until 12 June, by which time the Allies held a front around 97 kilometres (60 mi) long and 24 kilometres (15 mi) deep.[189] Caen, a major objective, was still in German hands at the end of D-Day and would not be completely captured until 21 July.[190] The Germans had ordered French civilians, other than those deemed essential to the war effort, to leave potential combat zones in Normandy.[191] Civilian casualties on D-Day and D+1 are estimated at 3,000 people.[192]

Victory in Normandy stemmed from several factors. German preparations along the Atlantic Wall were only partially finished; shortly before D-Day Rommel reported that construction was only 18 per cent complete in some areas as resources were diverted elsewhere.[193] The deceptions undertaken in Operation Fortitude were successful, leaving the Germans obligated to defend a huge stretch of coastline.[194] The Allies achieved and maintained air supremacy, which meant that the Germans were unable to make observations of the preparations underway in Britain and were unable to interfere via bomber attacks.[195] Transportation infrastructure in France was severely disrupted by Allied bombers and the French Resistance, making it difficult for the Germans to bring up reinforcements and supplies.[196] Some of the opening bombardment was off-target or not concentrated enough to have any impact,[151] but the specialised armour worked well except on Omaha, providing close artillery support for the troops as they disembarked onto the beaches.[197] Indecisiveness and an overly complicated command structure on the part of the German high command were also factors in the Allied success.[198]

War memorials and tourism

The La Cambe German war cemetery, near Bayeux

At Omaha Beach, parts of the Mulberry harbour are still visible, and a few of the beach obstacles remain. A memorial to the American National Guard sits at the location of a former German strongpoint. Pointe du Hoc is little changed from 1944, with the terrain covered with bomb craters and most of the concrete bunkers still in place. The Normandy American Cemetery and Memorial is nearby, in Colleville-sur-Mer.[199] A museum about the Utah landings is located at Sainte-Marie-du-Mont, and there is one dedicated to the activities of the American airmen at Sainte-Mère-Église. Two German military cemeteries are located nearby.[200]

Pegasus Bridge, a target of the British 6th Airborne, was the site of some of the earliest action of the Normandy landings. The bridge was replaced in 1994 by one similar in appearance, and the original is now housed on the grounds of a nearby museum complex.[201] Sections of Mulberry Harbour B still sit in the sea at Arromanches, and the well-preserved Longues-sur-Mer battery is nearby.[202] The Juno Beach Centre, opened in 2003, was funded by the Canadian federal and provincial governments, France, and Canadian veterans

The Battle Of Britain

1 – 5 Short Films

——————————–

The Battle of Britain (German: Luftschlacht um England, literally “Air battle for England”) is the name given to the Second World War air campaign waged by the German Air Force (Luftwaffe) against the United Kingdom during the summer and autumn of 1940. The Battle of Britain was the first major campaign to be fought entirely by air forces,[18] and was also the largest and most sustained aerial bombing campaign to that date.

The objective of the Nazi German forces was to achieve air superiority over the Royal Air Force (RAF), especially its Fighter Command. Beginning in July 1940, coastal shipping convoys and shipping centres, such as Portsmouth, were the main targets; one month later, the Luftwaffe shifted its attacks to RAF airfields and infrastructure. As the battle progressed, the Luftwaffe also targeted factories involved in World War II aircraft production and ground infrastructure. Eventually the Luftwaffe resorted to attacking areas of political significance and using terror bombing strategy.[nb 10]

By preventing Germany from gaining air superiority, the British forced Adolf Hitler to postpone and eventually cancel Operation Sea Lion, a planned amphibious and airborne invasion of Britain. However, Germany continued bombing operations on Britain, known as The Blitz. The failure of Nazi Germany to achieve its objective of destroying Britain’s air defences in order to force Britain to negotiate an armistice (or even surrender outright) is considered by historians to be its first major defeat in World War II and a crucial turning point in the conflict.[20]

The Battle of Britain has an unusual distinction in that it gained its name prior to being fought. The name is derived from a famous speech delivered by Prime Minister Winston Churchill in the House of Commons on June 18, more than three weeks prior to the generally accepted date for the start of the battle

… What General Weygand has called The Battle of France is over. The battle of Britain is about to begin. Upon this battle depends the survival of Christian civilisation. Upon it depends our own British life and the long continuity of our institutions and our Empire. The whole fury and might of the enemy must very soon be turned on us. Hitler knows that he will have to break us in this island or lose the war. If we can stand up to him, all Europe may be free and the life of the world may move forward into broad, sunlit uplands. But if we fail, then the whole world, including the United States, including all that we have known and cared for, will sink into the abyss of a new Dark Age made more sinister, and perhaps more protracted, by the lights of a perverted science. Let us therefore brace ourselves to our duties, and so bear ourselves that, if the British Empire and its Commonwealth last for a thousand years, men will still say, “This was their finest hour”.[21]

— Winston Churchill

Background

British Prime Minister Winston Churchill

The early stages of World War II saw successful German invasions on the continent aided decisively by the air power of the Luftwaffe, which was able to establish tactical air superiority with great efficiency. The distressing speed with which German forces defeated most of the defending armies in Norway during the spring of 1940 created a significant political crisis in Britain. In early May 1940, the Norway Debate questioned the fitness for office of the British Prime Minister Neville Chamberlain. On 10 May, the same day Winston Churchill became British Prime Minister, the Germans initiated the Battle of France with an aggressive invasion of French territory. RAF Fighter Command was desperately short of trained pilots and aircraft, but despite the objections of its commander Hugh Dowding that the diversion of his forces would leave home defences under-strength, Churchill sent fighter squadrons to support operations in France,[22] where the RAF suffered heavy losses.[23]

After the evacuation of British and French soldiers from Dunkirk and the French surrender on 22 June 1940, Hitler mainly focused his energies on the possibility of invading the Soviet Union[24] in the belief that the British, defeated on the continent and without European allies, would quickly come to terms.[25] The Germans were so convinced of an imminent armistice that they began constructing street decorations for the homecoming parades of victorious troops.[26] Although the British Foreign Secretary, Lord Halifax, and certain elements of the British public favoured a negotiated peace with an ascendant Germany, Churchill and a majority of his Cabinet refused to consider an armistice.[27] Instead, Churchill used his skilful rhetoric to harden public opinion against capitulation and to prepare the British for a long war. In his “This was their finest hour” speech of 18 June 1940, he declared that “the Battle of France is over. I expect that the Battle of Britain is about to begin.”[28]

After a series of military victories, Germany took control of huge territories in central, northern, and western Europe that mainly corresponded to the boundaries of the defeated countries of Poland, France, Denmark, Norway, Belgium, and the Netherlands. In addition to these conquests, the boundaries of Germany itself had already been swelled considerably by the annexation of Austria and Czechoslovakia in 1938 and 1939. Germany’s position thus seemed invincible to many Europeans. Hitler hoped for a negotiated peace with Britain, thus made no preparations for amphibious assault on a hostile shore. In any case, at the time, the only forces with experience in this type of warfare and modern equipment to support it were the Japanese, who became adept with it at the Battle of Wuhan in 1938.[29] On 11 July 1940, Grand Admiral Erich Raeder, Commander-in-Chief of the Kriegsmarine (German Navy), told Hitler that an invasion of Britain could only be contemplated as a last resort, and only after full air superiority had been achieved. The Kriegsmarine had been nearly crippled by the Norwegian Campaign, with many of its ships sunk or damaged, while the Royal Navy still had over 50 destroyers, 21 cruisers and eight battleships in the British Home Fleet.[30][31][nb 11] There was little that the weakened Kriegsmarine could do to stop the Royal Navy from intervening. The only alternative was to use the Luftwaffe’s dive bombers and torpedo bombers, which required air superiority to operate effectively. Grand Admiral Raeder said, “A powerful and effective air force might create conditions favourable for an invasion, whether it could was not in the Navy War Staff’s province.”[33]

Although he agreed with Raeder, Hitler ordered the preparation of a plan to invade the United Kingdom on July 16.[34] He hoped that news of the preparations would frighten the UK into peace negotiations. “Directive No. 16; On the Preparation of a Landing Operation against England” read, in part, as follows:

Since England, despite its militarily hopeless situation, still has not shown any signs of being prepared to negotiate, I have decided to prepare a landing operation against England and, if necessary, carry it out.

The objective of this operation is to eliminate the English home country as a base for the continuation of the war against Germany …
2) Included in these preparations is the bringing about of those preconditions which make a landing in England possible;
a) The English air force must have been beaten down to such an extent morally and in fact that it can no longer muster any power of attack worth mentioning against the German crossing. (italics added)[35][nb 12][36]

All preparations were to be made by mid-August. For secrecy, this directive was only issued to Commanders-in-Chief, but Hermann Göring passed it on to his Luftwaffe Air Fleet commanders by coded radio messages that were intercepted by Britain’s Y-Service and successfully decrypted by Hut 6 at Bletchley Park.[37]

The Kriegsmarine produced a draft plan for achieving a narrow beachhead near Dover. On 28 July the army responded that they wanted landings all along the south coast of England. Hitler held a meeting of his army and navy chiefs on 31 July in his residence of Berghof, and on 1 August the OKW (Oberkommando der Wehrmacht or “High Command of the Armed Forces”) issued its plan.[38] The plan, code named Operation Sea Lion, was scheduled to take place in mid-September 1940. Operation Sea Lion called for landings on the south coast of Great Britain backed by an airborne assault. Neither Hitler nor OKW believed it would be possible to carry out a successful amphibious assault on Britain until the RAF had been neutralised. Raeder believed that air superiority might make a successful landing possible although it would be a risky operation and require “absolute mastery over the Channel by our air forces”.[39]

For his part, Grand Admiral Karl Dönitz believed that air superiority was “not enough”. Dönitz later stated, “we possessed neither control of the air or the sea; nor were we in any position to gain it.”[40] Some writers, such as Derek Robinson, have agreed with Dönitz. Robinson argues that the massive superiority of the Royal Navy over the Kriegsmarine would have made Sea Lion a disaster and the Luftwaffe could not have prevented decisive intervention by British cruisers and destroyers, even with air superiority.[41][42] Williamson Murray argued that the task facing the Germans in summer 1940 was beyond their capabilities; the three German armed services were not capable of solving the problem of invading the British Isles. Murray contends that the Kriegsmarine had been effectively eliminated owing to heavy losses during the Norwegian Campaign.[43] and states that it is doubtful that the Kriegsmarine and Luftwaffe could have prevented the Royal Navy from engaging the invasion fleet.[44]

The Luftwaffe had not been represented at the Berghof, but Göring was confident that air victory was possible. Like many commanders in other air forces, including the RAF, he was convinced by the ideas of Giulio Douhet that “The bomber will always get through” and if attacks on military targets failed, the bombing of civilians could force the British government to surrender.[45]

Opposing forces

The Luftwaffe faced a more capable opponent than any it had previously met: a sizeable, highly coordinated, well-supplied, modern air force.

Fighters

The Luftwaffe’s Messerschmitt Bf 109E and Bf 110C fought against the RAF’s workhorse Hurricane Mk I and the less numerous Spitfire Mk I; Hurricanes outnumbered Spitfires in RAF Fighter Command by about two to one when war broke out.[46] The Bf 109E had a better climb rate and was up to 40 mph faster in level flight [47] than the Rotol (constant speed propellor) equipped Hurricane Mk I, depending on altitude. The speed and climb disparity with the original non-Rotol Hurricane was even greater. In spring and summer 1940, all RAF Spitfire and Hurricane fighter squadrons converted to 100 octane aviation fuel,[48] which allowed their Merlin engines to generate significantly more power and an approximately 30 mph increase in speed at low altitudes[49][50] through the use of an Emergency Boost Override.[51][52][53] In September 1940, the more powerful Mk IIa series 1 Hurricanes started entering service in small numbers.[54] This version was capable of a maximum speed of 342 mph (550 km/h), some 20 mph more than the original (non-Rotol) Mk I, though it was still 15 to 20 mph slower than a Bf 109 (depending on altitude).[55]

Hawker Hurricane R4118 fought in the Battle of Britain. Here it arrives at the 2014 Royal International Air Tattoo, England.

The performance of the Spitfire over Dunkirk came as a surprise to the Jagdwaffe, although the German pilots retained a strong belief that the 109 was the superior fighter.[56] The British fighters were equipped with eight Browning .303 (7.7mm) machine guns, while most Bf 109Es had two 7.92mm machine guns supplemented by two 20mm cannons.[nb 13] The latter was much more effective than the .303; many German planes landed despite large numbers of .303 hits. At some altitudes, the Bf 109 could outclimb the British fighter. It could also engage in vertical-plane negative-g manoeuvres without the engine cutting out because its DB 601 engine used fuel injection; this allowed the 109 to dive away from attackers more readily than the carburettor-equipped Merlin. On the other hand, the Bf 109E had a much larger turning circle than its two foes.[57] In general, though, as Alfred Price noted in The Spitfire Story:

… the differences between the Spitfire and the Me 109 in performance and handling were only marginal, and in a combat they were almost always surmounted by tactical considerations of which side had seen the other first, which had the advantage of sun, altitude, numbers, pilot ability, tactical situation, tactical co-ordination, amount of fuel remaining, etc.[58]

The Bf 109E was also used as a Jabo (jagdbomber, fighter-bomber)—the E-4/B and E-7 models could carry a 250 kg bomb underneath the fuselage, the later model arriving during the battle. The Bf 109, unlike the Stuka, could fight on equal terms with RAF fighters after releasing its ordnance.[59][60]

At the start of the battle, the twin-engined Messerschmitt Bf 110C long range Zerstörer (“Destroyer”) was also expected to engage in air-to-air combat while escorting the Luftwaffe bomber fleet. Although the 110 was faster than the Hurricane and almost as fast as the Spitfire, its lack of manoeuvrability and acceleration meant that it was a failure as a long-range escort fighter. On 13 and 15 August, 13 and 30 aircraft were lost, the equivalent of an entire Gruppe, and the type’s worst losses during the campaign.[61] This trend continued with a further eight and fifteen lost on 16 and 17 August.[62] Göring ordered the Bf 110 units to operate “where the range of the single-engined machines were not sufficient”.[citation needed]

The most successful role of the Bf 110 during the battle was as a Schnellbomber (fast bomber). The Bf 110 usually used a shallow dive to bomb the target and escape at high speed.[63][64] One unit, Erprobungsgruppe 210 – initially formed as the service test unit (Erprobungskommando) for the emerging successor to the 110, the Me 210 – proved that the Bf 110 could still be used to good effect in attacking small or “pinpoint” targets.[63]

Four 264 Squadron Defiants (PS-V was shot down on 28 August 1940 over Kent by Bf 109s.)

The RAF’s Boulton Paul Defiant had some initial success over Dunkirk because of its resemblance to the Hurricane; Luftwaffe fighters attacking from the rear were surprised by its unusual gun turret.[65] However, during the Battle of Britain, this single-engined two-seater proved hopelessly outclassed. For various reasons, the Defiant lacked any form of forward-firing armament, and the heavy turret and second crewman meant it could not outrun or outmanoeuvre either the Bf 109 or Bf 110. By the end of August, after disastrous losses, the aircraft was withdrawn from daylight service.[66][67]

Bombers

Heinkel He 111 bombers during the Battle of Britain

The Luftwaffe’s primary bombers were the Heinkel He 111, Dornier Do 17, and Junkers Ju 88 for level bombing at medium to high altitudes, and the Junkers Ju 87 Stuka for dive bombing tactics. The He 111 was used in greater numbers than the others during the conflict. Forming the main brunt of the heavy formations, it is better known, partly due to its distinctive wing shape. Each level bomber also had a few reconnaissance versions accompanying them that were used during the battle.[68]

Although it was successful in previous Luftwaffe engagements, the Stuka suffered heavy losses in the Battle of Britain, particularly on 18 August, due to its slow speed and vulnerability to fighter interception after dive bombing a target. As the losses went up along with their limited payload and range, Stuka units were largely removed from operations over England and diverted to concentrate on shipping instead until they were eventually re-deployed to the Eastern Front in 1941. However, for some raids, they were called back, such as on 13 September to attack Tangmere airfield.[69][70][71]

The remaining three bomber types differed in their capabilities; the Heinkel 111 was the slowest; the Ju 88 was the fastest once its mainly external bomb load was dropped; and the Do 17 had the smallest bomb load.[68] All three bomber types suffered heavy losses from the home-based British fighters, but the Ju 88 disproportionately so. The German bombers required constant protection by the Luftwaffe’s fighter force. German escorts, however, were not enough. Bf 109Es were ordered to support more than 300–400 bombers on any given day.[72] Later in the conflict, when night bombing became more frequent, all three were used. However, due to its reduced bomb load, the lighter Do 17 was used less than the He 111 and Ju 88 for this purpose.

On the British side, three bomber types were mostly used on night operations against targets such as factories, invasion ports and railway centres; the Armstrong Whitworth Whitley, the Handley-Page Hampden and the Vickers Wellington were classified as heavy bombers by the RAF, although the Hampden was a medium bomber comparable to the He 111. The twin-engined Bristol Blenheim and the obsolescent single-engined Fairey Battle were both light bombers; the Blenheim was the most numerous of the aircraft equipping RAF Bomber Command and was used in attacks against shipping, ports, airfields and factories on the continent by day and by night. The Fairey Battle squadrons, which had suffered heavy losses in daylight attacks during the Battle of France, were brought up to strength with reserve aircraft and continued to operate at night in attacks against the invasion ports, until the Battle was withdrawn from UK front line service in October 1940.[73][75]

Pilots

Before the war, the RAF’s processes for selecting potential candidates were opened to men of all social classes through the creation in 1936 of the RAF Volunteer Reserve, which “… was designed to appeal, to … young men … without any class distinctions …”[76] The older squadrons of the Royal Auxiliary Air Force did retain some of their upper-class exclusiveness,[77] but their numbers were soon swamped by the newcomers of the RAFVR; by 1 September 1939, 6,646 pilots had been trained through the RAFVR.[78]

A Spitfire pilot recounts how he shot down a Messerschmitt, Biggin Hill, September 1940

By summer 1940, there were about 9,000 pilots in the RAF to man about 5,000 aircraft, most of which were bombers.[citation needed] Fighter Command was never short of pilots, but the problem of finding sufficient numbers of fully trained-fighter pilots became acute by mid-August 1940.[79] With aircraft production running at 300 planes each week, only 200 pilots were trained in the same period. In addition, more pilots were allocated to squadrons than there were aircraft, as this allowed squadrons to maintain operational strength despite casualties and still provide for pilot leave.[80] Another factor was that only about 30% of the 9,000 pilots were assigned to operational squadrons; 20% of the pilots were involved in conducting pilot training, and a further 20% were undergoing further instruction, like those offered in Canada and in Southern Rhodesia to the Commonwealth trainees, although already qualified. The rest were assigned to staff positions, since RAF policy dictated that only pilots could make many staff and operational command decisions, even in engineering matters. At the height of fighting, and despite Churchill’s insistence, only 30 pilots were released to the front line from administrative duties.[81][nb 15]

For these reasons, and the permanent loss of 435 pilots during the Battle of France alone[23] along with many more wounded, and others lost in Norway, the RAF had fewer experienced pilots at the start of the initial defence of their home. It was the lack of trained pilots in the fighting squadrons, rather than the lack of aircraft, that became the greatest concern for Air Chief Marshal Hugh Dowding, Commander of Fighter Command. Drawing from regular RAF forces, the Auxiliary Air Force and the Volunteer Reserve, the British were able to muster some 1,103 fighter pilots on 1 July. Replacement pilots, with little flight training and often no gunnery training, suffered high casualty rates thus exacerbating the problem.[82]

The Luftwaffe on the other hand, were able to muster a larger number (1,450) of more experienced fighter pilots.[81] Drawing from a cadre of Spanish Civil War veterans, these pilots already had comprehensive courses in aerial gunnery and instructions in tactics suited for fighter-versus-fighter combat.[83] Training manuals discouraged heroism, stressing the importance of attacking only when the odds were in the pilot’s favour. Despite the high levels of experience, German fighter formations did not provide a sufficient reserve of pilots to allow for losses and leave,[80] and the Luftwaffe was unable to produce enough pilots to prevent a decline in operational strength as the battle progressed. Eventually, without the personnel available to continue the assault, the Luftwaffe failed during this segment of the war.

The Royal Air Force roll of honour for the Battle of Britain recognises 595 non-British pilots (out of 2,936) as flying at least one authorised operational sortie with an eligible unit of the RAF or Fleet Air Arm between 10 July and 31 October 1940.[13][84] These included 145 Poles, 127 New Zealanders, 112 Canadians, 88 Czechoslovaks, 10 Irish, 32 Australians, 28 Belgians, 25 South Africans, 13 French, 7 Americans, 3 Southern Rhodesians and one each from Jamaica and Mandatory Palestine.[85] “Altogether in the fighter battles, the bombing raids, and the various patrols flown between 10 July and 31 October 1940 by the Royal Air Force, 1495 aircrew were killed, of whom 449 were fighter pilots, 718 aircrew from Bomber Command, and 280 from Coastal Command. Among those killed were 47 airmen from Canada, 24 from Australia, 17 from South Africa, 35 from Poland, 20 from Czechoslovakia and six from Belgium. Forty-seven New Zealanders lost their lives, including 15 fighter pilots, 24 bomber and eight coastal aircrew. The names of these Allied and Commonwealth airmen are inscribed in a memorial book which rests in the Battle of Britain Chapel in Westminster Abbey. In the chapel is a stained glass window which contains the badges of the fighter squadrons which operated during the battle and the flags of the nations to which the pilots and aircrew belonged.”[86]

An element of the Italian Royal Air Force (Regia Aeronautica) called the Italian Air Corps (Corpo Aereo Italiano or CAI) first saw action in late October 1940. It took part in the latter stages of the battle, but achieved limited success. The unit was redeployed in early 1941.

Luftwaffe strategy

Hermann Göring, the commander of the Luftwaffe

Hugo Sperrle, the commander of Luftflotte 3

The Luftwaffe strategy was devised to provide tactical support for the army on the battlefield. During the blitzkrieg offensives against Poland, Denmark and Norway, France and the Low Countries, the Luftwaffe had co-operated fully with the Wehrmacht. For the Battle of Britain however, the Luftwaffe had to operate in a strategic role, something for which it was unsuited. Its main task was to ensure air supremacy over southeast England, to pave the way for an invasion fleet.

The Luftwaffe regrouped after the Battle of France into three Luftflotten (Air Fleets) on Britain’s southern and northern flanks. Luftflotte 2, commanded by Generalfeldmarschall Albert Kesselring, was responsible for the bombing of southeast England and the London area. Luftflotte 3, under Generalfeldmarschall Hugo Sperrle, targeted the West Country, Wales, the Midlands, and northwest England. Luftflotte 5, led by Generaloberst Hans-Jürgen Stumpff from his headquarters in Norway, targeted the north of England and Scotland. As the battle progressed, command responsibility shifted, with Luftflotte 3 taking more responsibility for the night-time Blitz attacks while the main daylight operations fell upon Luftflotte 2’s shoulders.

Initial Luftwaffe estimates were that it would take four days to defeat the RAF Fighter Command in southern England. This would be followed by a four-week offensive during which the bombers and long-range fighters would destroy all military installations throughout the country and wreck the British aircraft industry. The campaign was planned to begin with attacks on airfields near the coast, gradually moving inland to attack the ring of sector airfields defending London. Later reassessments gave the Luftwaffe five weeks, from 8 August to 15 September, to establish temporary air superiority over England.[87] To achieve this goal, Fighter Command had to be destroyed, either on the ground or in the air, yet the Luftwaffe had to be able to preserve its own strength to be able to support the invasion; this meant that the Luftwaffe had to maintain a high “kill ratio” over the RAF fighters. The only alternative to the goal of air superiority was a terror bombing campaign aimed at the civilian population, but this was considered a last resort and it was (at this stage of the battle) expressly forbidden by Hitler.[87]

The Luftwaffe kept broadly to this scheme, but its commanders had differences of opinion on strategy. Sperrle wanted to eradicate the air defence infrastructure by bombing it. His counterpart, Kesselring, championed attacking London directly— either to bombard the British government into submission, or to draw RAF fighters into a decisive battle. Göring did nothing to resolve this disagreement between his commanders, and only vague directives were set down during the initial stages of the battle, with Göring seemingly unable to decide upon which strategy to pursue.[88] He seemed at times obsessed with maintaining his own power base in the Luftwaffe and indulging his outdated beliefs on air fighting, which would later lead to tactical and strategic errors.

Tactics

Fighter formations

Luftwaffe formations employed a loose section of two (nicknamed the Rotte), based on a leader (Rottenführer) followed at a distance of about 183 metres (200 yards)[nb 16] by his wingman (nicknamed the Rottenhund or Katschmareks), who also flew slightly higher and was trained always to stay with his leader. With more room between them, both pilots could spend less time maintaining formation and more time looking around and covering each other’s blind spots. Attacking aircraft could be sandwiched between the two 109s.[89] [nb 17] The rotte allowed the Rottenführer to concentrate on getting kills, but few wingmen had the chance,[91] leading to some resentment in the lower ranks where it was felt that the high scores came at their expense. Two sections were usually teamed up into a Schwarm, where all the pilots could watch what was happening around them. Each Schwarm in a Staffel flew at staggered heights and with 183 metres (200 yards) of room between them, making the formation difficult to spot at longer ranges and allowing for a great deal of flexibility.[83] By utilising a tight “cross-over” turn, a Schwarm could quickly change direction.[89]

The Bf 110s adopted the same Schwarm formation as the 109s, but were seldom able to use this to the same advantage. The Bf 110’s most successful method of attack was the “bounce” from above. When attacked, Zerstörergruppen increasingly resorted to forming large “defensive circles“, where each Bf 110 guarded the tail of the aircraft ahead of it. Göring ordered that they be renamed “offensive circles” in a vain bid to improve rapidly declining morale.[92] These conspicuous formations were often successful in attracting RAF fighters that were sometimes “bounced” by high-flying Bf 109s. This led to the often repeated myth that the Bf 110s were escorted by Bf 109s.

Higher-level dispositions

Luftwaffe tactics were influenced by their fighters. The Bf 110 proved too vulnerable to the nimble single-engined RAF fighters. This meant the bulk of fighter escort duties fell on the Bf 109. Fighter tactics were then complicated by bomber crews who demanded closer protection. After the hard-fought battles of 15 and 18 August, Göring met with his unit leaders. During this conference, the need for the fighters to meet up on time with the bombers was stressed. It was also decided that one bomber Gruppe could only be properly protected by several Gruppen of 109s. In addition, Göring stipulated that as many fighters as possible were to be left free for Freie Jagd (“Free Hunts”: a free-roving fighter sweep preceded a raid to try to sweep defenders out of the raid’s path). The Ju 87 units, which had suffered heavy casualties, were only to be used under favourable circumstances.[93] In early September, due to increasing complaints from the bomber crews about RAF fighters seemingly able to get through the escort screen, Göring ordered an increase in close escort duties. This decision shackled many of the Bf 109s to the bombers and, although they were more successful at protecting the bomber forces, casualties amongst the fighters mounted primarily because they were forced to fly and manoeuvre at reduced speeds.[94]

The Luftwaffe consistently varied its tactics in its attempts to break through the RAF defences. It launched many Freie Jagd to draw up RAF fighters. RAF fighter controllers, however, were often able to detect these and position squadrons to avoid them, keeping to Dowding’s plan to preserve fighter strength for the bomber formations. The Luftwaffe also tried using small formations of bombers as bait, covering them with large numbers of escorts. This was more successful, but escort duty tied the fighters to the bombers’ slow speed and made them more vulnerable.

Pattern of condensation trails left by British and German aircraft after a dogfight.

By September, standard tactics for raids had become an amalgam of techniques. A Freie Jagd would precede the main attack formations. The bombers would fly in at altitudes between 16,000 feet (4,900 m) and 20,000 feet (6,100 m), closely escorted by fighters. Escorts were divided into two parts (usually Gruppen), some operating in close contact with the bombers, and others a few hundred yards away and a little above. If the formation was attacked from the starboard, the starboard section engaged the attackers, the top section moving to starboard and the port section to the top position. If the attack came from the port side the system was reversed. British fighters coming from the rear were engaged by the rear section and the two outside sections similarly moving to the rear. If the threat came from above, the top section went into action while the side sections gained height to be able to follow RAF fighters down as they broke away. If attacked, all sections flew in defensive circles. These tactics were skilfully evolved and carried out, and were extremely difficult to counter.[95]

Adolf Galland, the successful leader of III./JG 26, became Geschwaderkommodore of JG 26 on 22 August

Adolf Galland noted:

We had the impression that, whatever we did, we were bound to be wrong. Fighter protection for bombers created many problems which had to be solved in action. Bomber pilots preferred close screening in which their formation was surrounded by pairs of fighters pursuing a zigzag course. Obviously, the visible presence of the protective fighters gave the bomber pilots a greater sense of security. However, this was a faulty conclusion, because a fighter can only carry out this purely defensive task by taking the initiative in the offensive. He must never wait until attacked because he then loses the chance of acting.

We fighter pilots certainly preferred the free chase during the approach and over the target area. This gives the greatest relief and the best protection for the bomber force.[96]

The biggest disadvantage faced by Bf 109 pilots was that without the benefit of long-range drop tanks (which were introduced in limited numbers in the late stages of the battle), usually of 300 litres (66 imp gal; 79 US gal) capacity, the 109s had an endurance of just over an hour and, for the 109E, a 600 km (370 mi) range. Once over Britain, a 109 pilot had to keep an eye on a red “low fuel” light on the instrument panel: once this was illuminated, he was forced to turn back and head for France. With the prospect of two long flights over water, and knowing their range was substantially reduced when escorting bombers or during combat, the Jagdflieger coined the term Kanalkrankheit or “Channel sickness”.[97]

Intelligence

The Luftwaffe was ill-served by its lack of military intelligence about the British defences.[98] The German intelligence services were fractured and plagued by rivalries; their performance was “amateurish”.[99] By 1940, there were few German agents operating in Great Britain and a handful of bungled attempts to insert spies into the country were foiled.[100]

As a result of intercepted radio transmissions, the Germans began to realise that the RAF fighters were being controlled from ground facilities; in July and August 1939, for example, the airship Graf Zeppelin, which was packed with equipment for listening in on RAF radio and RDF transmissions, flew around the coasts of Britain. Although the Luftwaffe correctly interpreted these new ground control procedures, they were incorrectly assessed as being rigid and ineffectual. A British radar system was well known to the Luftwaffe from intelligence gathered before the war, but the highly developed “Dowding system” linked with fighter control had been a well-kept secret.[101][102] Even when good information existed, such as a November 1939 Abwehr assessment of Fighter Command strengths and capabilities by Abteilung V, it was ignored if it did not match conventional preconceptions.

On 16 July 1940, Abteilung V, commanded by Oberstleutnant “Beppo” Schmid, produced a report on the RAF and on Britain’s defensive capabilities which was adopted by the frontline commanders as a basis for their operational plans. One of the most conspicuous failures of the report was the lack of information on the RAF’s RDF network and control systems capabilities; it was assumed that the system was rigid and inflexible, with the RAF fighters being “tied” to their home bases.[103][104] An optimistic and, as it turned out, erroneous conclusion reached was:

D. Supply Situation… At present the British aircraft industry produces about 180 to 300 first line fighters and 140 first line bombers a month. In view of the present conditions relating to production (the appearance of raw material difficulties, the disruption or breakdown of production at factories owing to air attacks, the increased vulnerability to air attack owing to the fundamental reorganisation of the aircraft industry now in progress), it is believed that for the time being output will decrease rather than increase.

In the event of an intensification of air warfare it is expected that the present strength of the RAF will fall, and this decline will be aggravated by the continued decrease in production.[104]

Because of this statement, reinforced by another more detailed report, issued on 10 August, there was a mindset in the ranks of the Luftwaffe that the RAF would run out of frontline fighters.[103] The Luftwaffe believed it was weakening Fighter Command at three times the actual attrition rate.[105] Many times, the leadership believed Fighter Command’s strength had collapsed, only to discover that the RAF were able to send up defensive formations at will.

Throughout the battle, the Luftwaffe had to use numerous reconnaissance sorties to make up for the poor intelligence. Reconnaissance aircraft (initially mostly Dornier Do 17s, but increasingly Bf 110s) proved easy prey for British fighters, as it was seldom possible for them to be escorted by Bf 109s. Thus, the Luftwaffe operated “blind” for much of the battle, unsure of its enemy’s true strengths, capabilities, and deployments. Many of the Fighter Command airfields were never attacked, while raids against supposed fighter airfields fell instead on bomber or coastal defence stations. The results of bombing and air fighting were consistently exaggerated, due to inaccurate claims, over-enthusiastic reports and the difficulty of confirmation over enemy territory. In the euphoric atmosphere of perceived victory, the Luftwaffe leadership became increasingly disconnected from reality. This lack of leadership and solid intelligence meant the Germans did not adopt consistent strategy, even when the RAF had its back to the wall. Moreover, there was never a systematic focus on one type of target (such as airbases, radar stations, or aircraft factories); consequently, the already haphazard effort was further diluted.[106]

Navigational aids

While the British were using radar for air defence more effectively than the Germans realised, the Luftwaffe attempted to press its own offensive with advanced radio navigation systems of which the British were initially not aware. One of these was Knickebein (“bent leg”); this system was used at night and for raids where precision was required. It was rarely used during the Battle of Britain (see Reginald Victor Jones and Battle of the Beams).[107]

Air-sea rescue

The Luftwaffe was much better prepared for the task of air-sea rescue than the RAF, specifically tasking the Seenotdienst unit, equipped with about 30 Heinkel He 59 floatplanes, with picking up downed aircrew from the North Sea, English Channel and the Dover Straits. In addition, Luftwaffe aircraft were equipped with life rafts and the aircrew were provided with sachets of a chemical called fluorescein which, on reacting with water, created a large, easy-to-see, bright green patch.[108][109] In accordance with the Geneva Convention, the He 59s were unarmed and painted white with civilian registration markings and red crosses. Nevertheless, RAF aircraft attacked these aircraft, as some were escorted by Bf 109s.[110]

After single He 59s were forced to land on the sea by RAF fighters, on 1 and 9 July respectively,[110][111] a controversial order was issued to the RAF on 13 July; this stated that from 20 July, Seenotdienst aircraft were to be shot down. One of the reasons given by Churchill was:

We did not recognise this means of rescuing enemy pilots so they could come and bomb our civil population again … all German air ambulances were forced down or shot down by our fighters on definite orders approved by the War Cabinet.[112]

The British also believed that their crews would report on convoys,[109] the Air Ministry issuing a communiqué to the German government on 14 July that Britain was

unable, however, to grant immunity to such aircraft flying over areas in which operations are in progress on land or at sea, or approaching British or Allied territory, or territory in British occupation, or British or Allied ships. Ambulance aircraft which do not comply with the above will do so at their own risk and peril[113]

The white He 59s were soon repainted in camouflage colours and armed with defensive machine guns. Although another four He 59s were shot down by RAF aircraft,[114] the Seenotdienst continued to pick up downed Luftwaffe and Allied aircrew throughout the battle, earning praise from Adolf Galland for their bravery.[115]

Dowding system

Chain Home radar cover, bases and group boundaries

Main article: Dowding system

During early tests of the Chain Home system, the slow flow of information from the CH radars and observers to the aircraft often caused them to miss their “bandits”. The solution, today known as the “Dowding system“, was to create a set of reporting chains to move information from the various observation points to the pilots in their fighters. It was named after its chief architect, “Stuffy” Dowding.[116]

Reports from CH radars and the Observer Corps were sent directly to Fighter Command Headquarters (FCHQ) at Bentley Priory where they were “filtered” to combine multiple reports of the same formations into single tracks. Telephone operators would then forward only the information of interest to the Group headquarters, where the map would be re-created. This process was repeated to produce another version of the map at the Sector level, covering a much smaller area. Looking over their maps, Group level commanders could select squadrons to attack particular targets. From that point the Sector operators would give commands to the fighters to arrange an interception, as well as return them to base. Sector stations also controlled the anti-aircraft batteries in their area; an army officer sat beside each fighter controller and directed the gun crews when to open and cease fire.[117]

The Dowding system dramatically improved the speed and accuracy of the information that flowed to the pilots. During the early war period it was expected that an average interception mission might have a 30% chance of ever seeing their target. During the battle, the Dowding system maintained an average rate over 75%, with several examples of 100% rates – every fighter dispatched found and intercepted its target. In contrast, Luftwaffe fighters attempting to intercept raids had to randomly seek their targets and often returned home having never seen enemy aircraft. The result is what is now known as an example of “force multiplication“; RAF fighters were as effective as two or more Luftwaffe fighters, greatly offsetting, or overturning, the disparity in actual numbers.

Effect of signals intelligence

It is unclear how much the British intercepts of the Enigma cipher, used for high-security German radio communications, affected the battle. Ultra, the information obtained from Enigma intercepts, gave the highest echelons of the British command a view of German intentions. According to F. W. Winterbotham, who was the senior Air Staff representative in the Secret Intelligence Service,[118] Ultra helped establish the strength and composition of the Luftwaffe’s formations, the aims of the commanders[119] and provided early warning of some raids.[120] In early August it was decided that a small unit would be set up at FCHQ, which would process the flow of information from Bletchley and provide Dowding only with the most essential Ultra material; thus the Air Ministry did not have to send a continual flow of information to FCHQ, preserving secrecy, and Dowding was not inundated with non-essential information. Keith Park and his controllers were also told about Ultra.[121] In a further attempt to camouflage the existence of Ultra, Dowding created a unit named No. 421 (Reconnaissance) Flight RAF. This unit (which later became No. 91 Squadron RAF), was equipped with Hurricanes and Spitfires and sent out aircraft to search for and report Luftwaffe formations approaching England.[122] In addition the radio listening service (known as Y Service), monitoring the patterns of Luftwaffe radio traffic, contributed considerably to the early warning of raids.

Air-sea rescue

One of the biggest oversights of the entire system was the lack of adequate air-sea rescue organisation. The RAF had started organising a system in 1940 with High Speed Launches (HSLs) based on flying boat bases and at a number of overseas locations, but it was still believed that the amount of cross-Channel traffic meant that there was no need for a rescue service to cover these areas. Downed pilots and aircrew, it was hoped, would be picked up by any boats or ships which happened to be passing by. Otherwise the local life boat would be alerted, assuming someone had seen the pilot going into the water.[123]

RAF aircrew were issued with a life jacket, nicknamed the “Mae West,” but in 1940 it still required manual inflation, which was almost impossible for someone who was injured or in shock. The waters of the English Channel and Dover Straits are cold, even in the middle of summer, and clothing issued to RAF aircrew did little to insulate them against these freezing conditions.[98] The RAF also imitated the German practice of issuing fluorescein.[109] A conference in 1939 had placed air-sea rescue under Coastal Command. Because a number of pilots had been lost at sea during the “Channel Battle”, on 22 August, control of RAF rescue launches was passed to the local naval authorities and 12 Lysanders were given to Fighter Command to help look for pilots at sea. In all some 200 pilots and aircrew were lost at sea during the battle. No proper air-sea rescue service was formed until 1941.[98]

Fighter formations

In the late 1930s, Fighter Command expected to face only bombers over Britain, not single-engined fighters. A series of “Fighting Area Tactics” were formulated and rigidly adhered to, involving a series of manoeuvres designed to concentrate a squadron’s firepower to bring down bombers. RAF fighters flew in tight, v-shaped sections (“vics”) of three, with four such “sections” in tight formation. Only the squadron leader at the front was free to watch for the enemy; the other pilots had to concentrate on keeping station.[124] Training also emphasised by-the-book attacks by sections breaking away in sequence. Fighter Command recognised the weaknesses of this structure early in the battle, but it was felt too risky to change tactics during the battle, because replacement pilots—often with only minimal flying time—could not be readily retrained,[125] and inexperienced pilots needed firm leadership in the air only rigid formations could provide.[126] German pilots dubbed the RAF formations Idiotenreihen (“rows of idiots”) because they left squadrons vulnerable to attack.[82][127]

Front line RAF pilots were acutely aware of the inherent deficiencies of their own tactics. A compromise was adopted whereby squadron formations used much looser formations with one or two “weavers” flying independently above and behind to provide increased observation and rear protection; these tended to be the least experienced men and were often the first to be shot down without the other pilots even noticing that they were under attack.[82][128] During the battle, 74 Squadron under Squadron Leader Adolph “Sailor” Malan adopted a variation of the German formation called the “fours in line astern”, which was a vast improvement on the old three aircraft “vic”. Malan’s formation was later generally used by Fighter Command.[129]

Squadron- and higher-level deployment

The weight of the battle fell upon 11 Group. Keith Park’s tactics were to dispatch individual squadrons to intercept raids. The intention was to subject incoming bombers to continual attacks by relatively small numbers of fighters and try to break up the tight German formations. Once formations had fallen apart, stragglers could be picked off one by one. Where multiple squadrons reached a raid the procedure was for the slower Hurricanes to tackle the bombers while the more agile Spitfires held up the fighter escort. This ideal was not always achieved, resulting in occasions when Spitfires and Hurricanes reversed roles.[130] Park also issued instructions to his units to engage in frontal attacks against the bombers, which were more vulnerable to such attacks. Again, in the environment of fast moving, three-dimensional air battles, few RAF fighter units were able to attack the bombers from head-on.[130]

During the battle, some commanders, notably Leigh-Mallory, proposed squadrons be formed into “Big Wings,” consisting of at least three squadrons, to attack the enemy en masse, a method pioneered by Douglas Bader.

Douglas Bader commanded 242 Squadron during the battle. He also led the Duxford Wing.

Proponents of this tactic claimed interceptions in large numbers caused greater enemy losses while reducing their own casualties. Opponents pointed out the big wings would take too long to form up, and the strategy ran a greater risk of fighters being caught on the ground refuelling. The big wing idea also caused pilots to overclaim their kills, due to the confusion of a more intense battle zone. This led to the belief big wings were far more effective than they were.[131]

The issue caused intense friction between Park and Leigh-Mallory, as 12 Group was tasked with protecting 11 Group’s airfields whilst Park’s squadrons intercepted incoming raids. However, the delay in forming up Big Wings meant the formations often did not arrive at all or until after German bombers had hit 11 Group’s airfields.[132] Dowding, to highlight the problem of the Big Wing’s performance, submitted a report compiled by Park to the Air Ministry on 15 November. In the report, he highlighted that during the period of 11 September – 31 October, the extensive use of the Big Wing had resulted in just 10 interceptions and one German aircraft destroyed, but his report was ignored.[133] Post-war analysis agrees Dowding and Park’s approach was best for 11 Group.

Dowding’s removal from his post in November 1940 has been blamed on this struggle between Park and Leigh-Mallory’s daylight strategy. However, the intensive raids and destruction wrought during the Blitz damaged both Dowding and Park in particular, for the failure to produce an effective night-fighter defence system, something for which the influential Leigh-Mallory had long criticised them.[134]

Bomber and Coastal Command contributions

Bomber Command and Coastal Command aircraft flew offensive sorties against targets in Germany and France during the battle. After the initial disasters of the war, with Vickers Wellington bombers shot down in large numbers attacking Wilhelmshaven and the slaughter of the Fairey Battle squadrons sent to France, it became clear that Bomber Command would have to operate mainly at night to achieve any results without incurring very high losses.[135] From 15 May 1940, a night time bomber campaign was launched against the German oil industry, communications, and forests/crops, mainly in the Ruhr area.

As the threat mounted, Bomber Command changed targeting priority on 3 June 1940 to attack the German aircraft industry. On 4 July, the Air Ministry gave Bomber Command orders to attack ports and shipping. By September, the build-up of invasion barges in the Channel ports had become a top priority target.[136] On 7 September, the government issued a warning that the invasion could be expected within the next few days and, that night, Bomber Command attacked the Channel ports and supply dumps. On 13 September, they carried out another large raid on the Channel ports, sinking 80 large barges in the port of Ostend.[137] 84 barges were sunk in Dunkirk after another raid on 17 September and by 19 September, almost 200 barges had been sunk.[136] The loss of these barges may have contributed to Hitler’s decision to postpone Operation Sea Lion indefinitely.[136] The success of these raids was in part because the Germans had few Freya radar stations set up in France, so that air defences of the French harbours were not nearly as good as the air defences over Germany; Bomber Command had directed some 60% of its strength against the Channel ports.

The Bristol Blenheim units also raided German-occupied airfields throughout July to December 1940, both during daylight hours and at night. Although most of these raids were unproductive, there were some successes; on 1 August, five out of 12 Blenheims sent to attack Haamstede and Evere (Brussels) were able to bomb, destroying or heavily damaging three Bf 109s of II./JG 27 and apparently killing a Staffelkapitän identified as a Hauptmann Albrecht von Ankum-Frank. Two other 109s were claimed by Blenheim gunners.[138][nb 18] Another successful raid on Haamstede was made by a single Blenheim on 7 August which destroyed one 109 of 4./JG 54, heavily damaged another and caused lighter damage to four more.[139]

There were some missions which produced an almost 100% casualty rate amongst the Blenheims; one such operation was mounted on 13 August 1940 against a Luftwaffe airfield near Aalborg in north-eastern Denmark by 12 aircraft of 82 Squadron. One Blenheim returned early (the pilot was later charged and due to appear before a court martial, but was killed on another operation), the other 11, which reached Denmark, were shot down, five by flak and six by Bf 109s. Of the 33 crewmen who took part in the attack, 20 were killed and 13 captured.[140]

As well as the bombing operations, Blenheim-equipped units had been formed to carry out long-range strategic reconnaissance missions over Germany and German-occupied territories. In this role, the Blenheims again proved to be too slow and vulnerable against Luftwaffe fighters, and they took constant casualties.[141]

Coastal Command directed its attention towards the protection of British shipping, and the destruction of enemy shipping. As invasion became more likely, it participated in the strikes on French harbours and airfields, laying mines, and mounting numerous reconnaissance missions over the enemy-held coast. In all, some 9,180 sorties were flown by bombers from July to October 1940. Although this was much less than the 80,000 sorties flown by fighters, bomber crews suffered about half the total number of casualties borne by their fighter colleagues. The bomber contribution was, therefore, much more dangerous on a loss-per-sortie comparison.[142]

Bomber, reconnaissance, and antisubmarine patrol operations continued throughout these months with little respite and none of the publicity accorded to Fighter Command. In his famous 20 August speech about “The Few“, praising Fighter Command, Churchill also made a point of mentioning Bomber Command’s contribution, adding that bombers were even then striking back at Germany; this part of the speech is often overlooked, even today.[143][144] The Battle of Britain Chapel in Westminster Abbey lists in a roll of honour, 718 Bomber Command crew members, and 280 from Coastal Command who were killed between 10 July and 31 October.[145]

Phases of the battle

The battle can be roughly divided into four phases:

  • 10 July – 11 August: Kanalkampf (“the Channel battles”)
  • 12–23 August: Adlerangriff (“Eagle Attack”), the early assault against the coastal airfields
  • 24 August – 6 September: the Luftwaffe targets the airfields. The critical phase of the battle.
  • 7 September onwards: the day attacks switch to British towns and cities.

Channel battles

The Kanalkampf comprised a series of running fights over convoys in the English Channel. It was launched partly because Kesselring and Sperrle were not sure about what else to do, and partly because it gave German aircrews some training and a chance to probe the British defences.[88] Dowding could only provide minimal shipping protection, and these battles off the coast tended to favour the Germans, whose bomber escorts had the advantage of altitude and outnumbered the RAF fighters. From 9 July reconnaissance probing by Dornier Do 17 bombers put a severe strain on RAF pilots and machines, with high RAF losses to Bf 109s. When nine 141 Squadron Defiants went into action on 19 July six were lost to Bf 109s before a squadron of Hurricanes intervened. On 25 July a coal convoy and escorting destroyers suffered such heavy losses to attacks by Stuka dive bombers that the Admiralty decided convoys should travel at night: the RAF shot down 16 raiders but lost 7 aircraft. By 8 August 18 coal ships and 4 destroyers had been sunk, but the Navy was determined to send a convoy of 20 ships through rather than move the coal by railway. After repeated Stuka attacks that day, six ships were badly damaged, four were sunk and only four reached their destination. The RAF lost 19 fighters and shot down 31 German aircraft. The Navy now cancelled all further convoys through the Channel and sent the cargo by rail. Even so, these early combat encounters provided both sides with experience.[146]

Main assault

The main attack upon the RAF’s defences was code-named Adlerangriff (“Eagle Attack”).

Poor weather delayed Adlertag (“Eagle Day”) until 13 August 1940. On 12 August, the first attempt was made to blind the Dowding system, when aircraft from the specialist fighter-bomber unit Erprobungsgruppe 210 attacked four radar stations. Three were briefly taken off the air but were back working within six hours.[147] The raids appeared to show that British radars were difficult to knock out. The failure to mount follow-up attacks allowed the RAF to get the stations back on the air, and the Luftwaffe neglected strikes on the supporting infrastructure, such as phone lines and power stations, which could have rendered the radars useless, even if the towers themselves (which were very difficult to destroy) remained intact.[106]

Adlertag opened with a series of attacks, led again by Epro 210,[147] on coastal airfields used as forward landing grounds for the RAF fighters, as well as ‘satellite airfields’[nb 19] (including Manston and Hawkinge).[147] As the week drew on, the airfield attacks moved further inland, and repeated raids were made on the radar chain. 15 August was “The Greatest Day” when the Luftwaffe mounted the largest number of sorties of the campaign. Luftflotte 5 attacked the north of England. Believing Fighter Command strength to be concentrated in the south, raiding forces from Denmark and Norway ran into unexpectedly strong resistance. Inadequately escorted by Bf 110s, bombers were shot down in large numbers. North East England was attacked by 65 Heinkel 111s escorted by 34 Messerschmitt 110s, and RAF Great Driffield was attacked by 50 unescorted Junkers 88s. Out of 115 bombers and 35 fighters sent, 16 bombers and 7 fighters were destroyed.[148] As a result of these casualties, Luftflotte 5 did not appear in strength again in the campaign.

18 August, which had the greatest number of casualties to both sides, has been dubbed “The Hardest Day“. Following this grinding battle, exhaustion and the weather reduced operations for most of a week, allowing the Luftwaffe to review their performance. “The Hardest Day” had sounded the end for the Ju 87 in the campaign.[149] This veteran of Blitzkrieg was too vulnerable to fighters to operate over Britain. So as to preserve the Stuka force, Göring withdrew them from the fighting. This removed the main Luftwaffe precision-bombing weapon and shifted the burden of pinpoint attacks on the already-stretched Erpro 210. The Bf 110 proved too clumsy for dogfighting with single-engined fighters, and its participation was scaled back. It would only be used when range required it or when sufficient single-engined escort could not be provided for the bombers.

Göring made yet another fateful decision: to order more bomber escorts at the expense of free-hunting sweeps. To achieve this, the weight of the attack now fell on Luftflotte 2, and the bulk of the Bf 109s in Luftflotte 3 were transferred to Kesselring’s command, reinforcing the fighter bases in the Pas-de-Calais. Stripped of its fighters, Luftflotte 3 would concentrate on the night bombing campaign. Göring, expressing disappointment with the fighter performance thus far in the campaign, also made sweeping changes in the command structure of the fighter units, replacing many Geschwaderkommodore with younger, more aggressive pilots like Adolf Galland and Werner Mölders.[150]

Finally, Göring stopped the attacks on the radar chain. These were seen as unsuccessful, and neither the Reichsmarschall nor his subordinates realised how vital the Chain Home stations were to the defence systems. It was known that radar provided some early warning of raids, but the belief among German fighter pilots was that anything bringing up the “Tommies” to fight was to be encouraged.

Göring ordered attacks on aircraft factories on 19 August 1940; on 23 August 1940 he ordered that RAF airfields be attacked. That evening an attack was mounted on a tyre factory in Birmingham. Raids on airfields continued through 24 August, and Portsmouth was hit by a major attack. That night, several areas of London were bombed; the East End was set ablaze and bombs landed on central London. Some historians believe that these bombs were dropped accidentally by a group of Heinkel He 111s which had failed to find their target; this account has been contested.[151] In retaliation, the RAF bombed Berlin on the night of 25–26 August, and continued bombing raids on Berlin. Göring’s pride was hurt, as he had previously claimed the British would never be able to bomb the city. The attacks enraged Hitler, who ordered retaliatory attacks on London.[152]

From 24 August onwards, the battle was a fight between Kesselring’s Luftflotte 2 and Park’s 11 Group. The Luftwaffe concentrated all their strength on knocking out Fighter Command and made repeated attacks on the airfields. Of the 33 heavy attacks in the following two weeks, 24 were against airfields. The key sector stations were hit repeatedly: Biggin Hill and Hornchurch four times each; Debden and North Weald twice each. Croydon, Gravesend, Rochford, Hawkinge and Manston were also attacked in strength. Coastal Command‘s Eastchurch was bombed at least seven times because it was believed to be a Fighter Command aerodrome. At times these raids caused some damage to the sector stations, threatening the integrity of the Dowding system.

To offset some losses, some 58 Fleet Air Arm fighter pilot volunteers were seconded to RAF squadrons, and a similar number of former Fairey Battle pilots were used. Most replacements from Operational Training Units (OTUs) had as little as nine hours flying time and no gunnery or air-to-air combat training. At this point, the multinational nature of Fighter Command came to the fore. Many squadrons and personnel from the air forces of the Dominions were already attached to the RAF, including top level commanders – Australians, Canadians, New Zealanders, Rhodesians and South Africans. In addition, there were other nationalities represented, including Free French, Belgian and a Jewish pilot from the British mandate of Palestine.

They were bolstered by the arrival of fresh Czechoslovak and Polish squadrons. These had been held back by Dowding, who mistakenly thought non-English speaking aircrew would have trouble working within his control system: Polish and Czech fliers proved to be especially effective. The pre-war Polish Air Force had lengthy and extensive training, and high standards; with Poland conquered and under brutal German occupation, the pilots of No. 303 (Polish) Squadron, the highest-scoring Allied unit,[153] were strongly motivated. Josef František, a Czech regular airman who had flown from the occupation of his own country to join the Polish and then French air forces before arriving in Britain, flew as a guest of 303 Squadron and was ultimately credited with the highest “RAF score” in the Battle of Britain.[154]

The RAF had the advantage of fighting over home territory. Pilots who bailed out of their downed aircraft could be back at their airfields within hours, while if low on fuel and/or ammunition they could be immediately rearmed.[155] One RAF pilot interviewed in late 1940 had been shot down five times during the Battle of Britain, but was able to crash land in Britain or bail out each time.[156] For Luftwaffe aircrews, a bailout over England meant capture – in the critical August period, almost exactly as many Luftwaffe pilots were taken prisoner as were killed[157] – while parachuting into the English Channel often meant drowning or death from exposure. Morale began to suffer, and [Kanalkrankheit] (“Channel sickness”) – a form of combat fatigue – began to appear among the German pilots. Their replacement problem was even worse than the British.

Impact of offensive

The effect of the German attacks on airfields is unclear. According to Stephen Bungay, Dowding, in a letter to Hugh Trenchard[158] accompanying Park’s report on the period 8 August – 10 September 1940, states that the Luftwaffe “achieved very little” in the last week of August and the first week of September.[159] The only Sector Station to be shut down operationally was Biggin Hill, and it was non-operational for just two hours. Dowding admitted 11 Group’s efficiency was impaired but, despite serious damage to some airfields, only two out of 13 heavily attacked airfields were down for more than a few hours. The German refocus on London was not critical.[159]

Retired air marshal Peter Dye, head of the RAF Museum, discussed the logistics of the battle in 2000[160] and 2010,[161] dealing specifically with the single-seat fighters. Dye contends that not only was British aircraft production replacing aircraft, but replacement pilots were keeping pace with losses. The number of pilots in RAF Fighter Command increased during July, August and September. The figures indicate the number of pilots available never decreased. From July, 1,200 were available. In 1 August, 1,400 were available. Just over that number were in the field by September. In October the figure was nearly 1,600. By 1 November 1,800 were available. Throughout the battle, the RAF had more fighter pilots available than the Luftwaffe.[160][161] Although the RAF’s reserves of single seat fighters fell during July, the wastage was made up for by an efficient Civilian Repair Organisation (CRO), which by December had repaired and put back into service some 4,955 aircraft,[162] and by aircraft held at Air Servicing Unit (ASU) airfields.[163]

Richard Overy agrees with Dye and Bungay. Overy asserts only one airfield was temporarily put out of action and “only” 103 pilots were lost. British fighter production produced 496 new aircraft in July and 467 in August, and another 467 in September (not counting repaired aircraft), covering the losses of August and September. Overy indicates the number of serviceable and total strength returns reveal an increase in fighters from 3 August to 7 September, 1,061 on strength and 708 serviceable to 1,161 on strength and 746 serviceable.[164] Moreover, Overy points out that the number of RAF fighter pilots grew by one-third between June and August 1940. Personnel records show a constant supply of around 1,400 pilots in the crucial weeks of the battle. In the second half of September it reached 1,500. The shortfall of pilots was never above 10%. The Germans never had more than between 1,100 and 1,200 pilots, a deficiency of up to one-third. “If Fighter Command were ‘the few’, the German fighter pilots were fewer”.[165]

Other scholars assert that this period was the most dangerous of all. In The Narrow Margin, published in 1961, historians Derek Wood and Derek Dempster believed that the two weeks from 24 August to 6 September represented a real danger. According to them, from 24 August to 6 September 295 fighters had been totally destroyed and 171 badly damaged, against a total output of 269 new and repaired Spitfires and Hurricanes. They assert that 103 pilots were killed or missing and 128 were wounded, which represented a total wastage of 120 pilots per week out of a fighting strength of just fewer than 1,000. They conclude that during August no more than 260 fighter pilots were turned out by OTUs and casualties in the same month were just over 300. A full squadron establishment was 26 pilots whereas the average in August was 16. In their assessment, the RAF was losing the battle.[166] Denis Richards, in his 1953 contribution to the official British account History of the Second World War, agreed that lack of pilots, especially experienced ones, was the RAF’s greatest problem. He states that between 8 and 18 August 154 RAF pilots were killed, severely wounded, or missing, while only 63 new pilots were trained. Availability of aircraft was also a serious issue. While its reserves during the Battle of Britain never declined to a half dozen planes as some later claimed, Richards describes 24 August to 6 September as the critical period because during these two weeks Germany destroyed far more aircraft through its attacks on 11 Group’s southeast bases than Britain was producing. Three more weeks of such a pace would indeed have exhausted aircraft reserves. Germany had seen heavy losses of pilots and aircraft as well however, thus its shift to night-time attacks in September. On 7 September RAF aircraft losses fell below British production and remained so until the end of the war.[167]

Raids on British cities

Main articles: The Blitz and Battle of Britain Day

Calais, September 1940. Göring giving a speech to pilots about the change in tactics: to bomb the towns instead of the airfields

Hitler’s No. 17 Directive on the conduct of war against the United Kingdom, issued on 1 August 1940, specifically prohibited the Luftwaffe from conducting terror raids on its own initiative, and reserved the right of ordering terror attacks as means of reprisal for the Führer himself:[168]

The war against England is to be restricted to destructive attacks against industry and air force targets which have weak defensive forces … The most thorough study of the target concerned, that is vital points of the target, is a pre-requisite for success. It is also stressed that every effort should be made to avoid unnecessary loss of life amongst the civilian population.[169]

The Luftwaffe offensive against Britain had included numerous raids on major ports since August, but Hitler had issued a directive that London was not to be bombed save on his sole instruction.[170] However, on the afternoon of 15 August, Hauptmann Walter Rubensdörffer leading Erprobungsgruppe 210 mistakenly bombed the Croydon airfield (on the outskirts of London) instead of the intended target, RAF Kenley;[171] this was followed on the night of 23/24 August[137] by the accidental bombing of Harrow, also on the outskirts of London, as well as raids on Aberdeen, Bristol, and South Wales. The focus on attacking airfields had also been accompanied by a sustained bombing campaign which began on 24 August with the largest raid so far, killing 100 in Portsmouth, and that evening the first night raid on London as described above.[151] On 25 August 1940, 81 bombers of Bomber Command were sent out to raid industrial and commercial targets in Berlin. Clouds prevented accurate identification and the bombs fell across the city, causing some casualties among the civilian population as well as damage to residential areas.[172] Continuing RAF raids on Berlin in retaliation led to Hitler withdrawing his directive,[173] and on 3 September Göring planned to bomb London daily, with General Albert Kesselring‘s enthusiastic support, having received reports the average strength of RAF squadrons was down to five or seven fighters out of twelve and their airfields in the area were out of action. Hitler issued a directive on 5 September to attack cities including London.[174][175] In his speech delivered on 4 September 1940, Hitler threatened to obliterate (ausradieren) British cities if British bombing runs against Germany did not stop.

Bombing of London

On 7 September, a massive series of raids involving nearly four hundred bombers and more than six hundred fighters targeted docks in the East End of London, day and night. The raids were code named Operation Loge. The RAF anticipated attacks on airfields and 11 Group rose to meet them, in greater numbers than the Luftwaffe expected. The first official deployment of 12 Group’s Lee-Mallory’s Big Wing took twenty minutes to form up, missing its intended target, but encountering another formation of bombers while still climbing. They returned, apologetic about their limited success, and blamed the delay on being scrambled too late.[152][176] Fighter Command had been at its lowest ebb, short of men and machines, and the break from airfield attacks allowed them to recover. 11 Group had considerable success in breaking up daytime raids. 12 Group repeatedly disobeyed orders and failed to meet requests to protect 11 Group airfields, but their experiments with increasingly large Big Wings had some success. The Luftwaffe began to abandon their morning raids, with attacks on London starting late in the afternoon for fifty-seven consecutive nights.[177]

The most damaging aspect to the Luftwaffe of targeting London was the increase in range. The Bf 109E escorts had a limited fuel capacity resulting in only a 660 km (410 mile) maximum range solely on internal fuel,[178] and when they arrived had only 10 minutes of flying time before turning for home, leaving the bombers undefended by fighter escorts. Its eventual stablemate, the Focke-Wulf Fw 190A, was only flying in prototype form in the summer of 1940; the first 28 Fw 190s were not delivered until November 1940. The Fw 190A-1 had a maximum range of 940 km (584 miles) on internal fuel, 40% greater than the Bf 109E.[179] The Messerschmitt Bf 109E-7 corrected this deficiency by adding a ventral center-line ordnance rack to take either an SC 250 bomb or a standard 300 litre Luftwaffe drop tank to double the range to 1,325 km (820 mi). The ordnance rack was not retrofitted to earlier Bf 109Es until October 1940.

On 14 September, Hitler chaired a meeting with the OKW staff. Göring was in France directing the decisive battle, so Erhard Milch deputized for him.[180] Hitler asked “Should we call it off altogether?”. General Hans Jeschonnek, Luftwaffe Chief of Staff, begged for a last chance to defeat the RAF and for permission to launch attacks on civilian residential areas to cause mass panic. Hitler refused the latter, perhaps unaware of how much damage had already been done to civilian targets. He reserved for himself the power to unleash the terror weapon. Instead political will was to be broken by destroying the material infrastructure, the weapons industry, and stocks of fuel and food.

On 15 September, two massive waves of German attacks were decisively repulsed by the RAF by deploying every aircraft in 11 Group. Sixty German and 26 RAF aircraft were shot down. Two days after the German defeat Hitler postponed preparations for the invasion of Britain. Henceforth, in the face of mounting losses in men, aircraft and the lack of adequate replacements, the Luftwaffe switched from daylight to nighttime bombing. 15 September is commemorated as Battle of Britain Day.

On 16 September, Göring ordered the air fleets to begin the new phase of the battle.[181] Hitler hoped this might result in “eight million going mad” (referring to the population of London in 1940), which would “cause a catastrophe” for the British. In those circumstances, Hitler said, “even a small invasion might go a long way”. Hitler was against cancelling the invasion as “the cancellation would reach the ears of the enemy and strengthen his resolve”.[nb 20][nb 21]

Gun camera film shows tracer ammunition from a Supermarine Spitfire Mark I of 609 Squadron, flown by Flight Lieutenant J H G McArthur, hitting a Heinkel He 111 on its starboard quarter. These aircraft were part of a large formation from KG 53 and 55 which attacked the Bristol Aeroplane Company’s works at Filton, Bristol, just before midday on 25 September 1940.

A Junkers Ju 88 returning from a raid on London was shot down in Kent on 27 September resulting in the Battle of Graveney Marsh, the last action between British and foreign military forces on British mainland soil.[183]

Hitler postponed the invasion on 13 October “until the spring of 1941”, and October is regarded as the month regular bombing of Britain ended. It was not until Hitler’s Directive 21 was issued, on 18 December 1940, that the threat of invasion finally ended.[137]

During the battle, and for the rest of the war, an important factor in keeping public morale high was the continued presence in London of King George VI and his wife Queen Elizabeth. When war broke out in 1939, the King and Queen decided to stay in London and not flee to Canada, as had been suggested.[nb 22] George VI and Elizabeth officially stayed in Buckingham Palace throughout the war, although they often spent weekends at Windsor Castle to visit their daughters, Elizabeth (the future queen) and Margaret.[184] Buckingham Palace was damaged by bombs which landed in the grounds on 10 September and, on 13 September, more serious damage was caused by two bombs which destroyed the Royal Chapel. The royal couple were in a small sitting room about 80 yards from where the bombs exploded.[185][186] On 24 September, in recognition of the bravery of civilians, King George VI inaugurated the award of the George Cross.

Attrition statistics

Overall, by 2 November, the RAF fielded 1,796 pilots, an increase of over 40% from July 1940’s count of 1,259 pilots.[187] Based on German sources (from a Luftwaffe intelligence officer Otto Bechtle attached to KG 2 in February 1944) translated by the Air Historical Branch, Stephen Bungay asserts German fighter and bomber “strength” declined without recovery, and that from August – December 1940, the German fighter and bomber strength declined by 30 and 25 percent.[11] In contrast, Williamson Murray, argues (using translations by the Air Historical Branch) that 1,380 German bombers were on strength on 29 June 1940,[9][188] 1,420 bombers on 28 September,[189] 1,423 level bombers on 2 November[190] and 1,393 bombers on 30 November 1940.[190] In July – September the number of Luftwaffe pilots available fell by 136, but the number of operational pilots had shrunk by 171 by September. The training organisation of the Luftwaffe was failing to replace losses. German fighter pilots, in contrast to popular perception, were not afforded training or rest rotations unlike their British counterparts.[80] The first week of September accounted for 25% of the Fighter Command, and 24% of the Luftwaffe’s overall losses.[191] Between the dates 26 August – 6 September, on only one day (1 September) did the Germans destroy more aircraft than they lost. Losses were 325 German and 248 British.[192]

Luftwaffe losses for August numbered 774 aircraft to all causes, representing 18.5% of all combat aircraft at the beginning of the month.[193] Fighter Command’s losses in August were 426 fighters destroyed,[194] amounting to 40 per cent of 1,061 fighters available on 3 August.[195] In addition, 99 German bombers and 27 other types were destroyed between 1 and 29 August.[196]

From July to September, the Luftwaffe’s loss records indicate the loss of 1,636 aircraft, 1,184 to enemy action.[188] This represented 47% of the initial strength of single-engined fighters, 66% of twin-engined fighters, and 45% of bombers. This indicates the Germans were running out of aircrews as well as aircraft.[197]

Throughout the battle, the Germans greatly underestimated the size of the RAF and the scale of British aircraft production. Across the Channel, the Air Intelligence division of the Air Ministry consistently overestimated the size of the German air enemy and the productive capacity of the German aviation industry. As the battle was fought, both sides exaggerated the losses inflicted on the other by an equally large margin. However, the intelligence picture formed before the battle encouraged the Luftwaffe to believe that such losses pushed Fighter Command to the very edge of defeat, while the exaggerated picture of German air strength persuaded the RAF that the threat it faced was larger and more dangerous than was the case.[198] This led the British to the conclusion that another fortnight of attacks on airfields might force Fighter Command to withdraw their squadrons from the south of England. The German misconception, on the other hand, encouraged first complacency, then strategic misjudgement. The shift of targets from air bases to industry and communications was taken because it was assumed that Fighter Command was virtually eliminated.[199]

Between the 24 August and 4 September, German serviceability rates, which were acceptable at Stuka units, were running at 75% with Bf 109s, 70% with bombers and 65% with Bf 110s, indicating a shortage of spare parts. All units were well below established strength. The attrition was beginning to affect the fighters in particular.”[200] By 14 September, the Luftwaffe’s Bf 109 Geschwader possessed only 67% of their operational crews against authorised aircraft. For Bf 110 units it was 46 per cent; and for bombers it was 59 per cent. A week later the figures had dropped to 64 per cent, 52% and 52 per cent.[197] Serviceability rates in Fighter Command’s fighter squadrons, between the 24 August and 7 September, were listed as: 64.8% on 24 August; 64.7% on 31 August and 64.25% on 7 September 1940.[195]

Due to the failure of the Luftwaffe to establish air supremacy, a conference assembled on 14 September at Hitler’s headquarters. Hitler concluded that air superiority had not yet been established and “promised to review the situation on 17 September for possible landings on 27 September or 8 October. Three days later, when the evidence was clear that the German Air Force had greatly exaggerated the extent of their successes against the RAF, Hitler postponed Sea Lion indefinitely.”[201]

Aftermath

The Battle of Britain marked the first defeat of Hitler’s military forces, with air superiority seen as the key to victory.[202] Pre-war theories had led to exaggerated fears of strategic bombing, and UK public opinion was buoyed by coming through the ordeal.[203] For the RAF, Fighter Command had achieved a great victory in successfully carrying out Sir Thomas Inskip’s 1937 air policy of preventing the Germans from knocking Britain out of the war. Churchill concluded his famous 18 June ‘Battle of Britain’ speech in the House of Commons by referring to pilots and aircrew who fought the Battle: “… if the British Empire and its Commonwealth lasts for a thousand years, men will still say, ‘This was their finest hour.'”[204][nb 23]

The battle also significantly shifted American opinion. During the battle, many Americans accepted the view promoted by Joseph Kennedy, the American ambassador in London, who believed that the United Kingdom could not survive. Roosevelt wanted a second opinion, and sent “Wild Bill” Donovan on a brief visit to the UK; he became convinced the UK would survive and should be supported in every possible way.[205][206] Before the end of the year, American journalist Ralph Ingersoll, who had been in Britain, published an influential book concluding that “Adolf Hitler met his first defeat in eight years” in what might “go down in history as a battle as important as Waterloo or Gettysburg“. The turning point was when the Germans reduced the intensity of the Blitz after 15 September. According to Ingersoll, “[a] majority of responsible British officers who fought through this battle believe that if Hitler and Göring had had the courage and the resources to lose 200 planes a day for the next five days, nothing could have saved London”; instead, “[the Luftwaffe’s] morale in combat is definitely broken, and the RAF has been gaining in strength each week.”[207]

Both sides in the battle made exaggerated claims of numbers of enemy aircraft shot down. In general, claims were two to three times the actual numbers, because of the confusion of fighting in dynamic three-dimensional air battles. Postwar analysis of records has shown that between July and September, the RAF claimed 2,698 kills, while the Luftwaffe fighters claimed 3,198 RAF aircraft downed. Total losses, and start and end dates for recorded losses, vary for both sides. Luftwaffe losses from 10 July to 30 October 1940 total 1,652 aircraft, including 229 twin- and 533 single-engined fighters.[208] In the same period, RAF Fighter Command aircraft losses number 1,087, including 53 twin-engined fighters.[208] To the RAF figure should be added 376 Bomber Command and 148 Coastal Command aircraft conducting bombing, mining, and reconnaissance operations in defence of the country.[11]

Dr. Andrew Gordon, who lectures at the Joint Services Command and Staff College, and a former lecturer Professor Gary Sheffield, have suggested the existence of the Royal Navy was enough to prevent the Germans from invading;[209] even had the Luftwaffe won the air battle, the Germans had limited means with which to combat the Royal Navy, which would have intervened to prevent a landing. Some veterans of the battle point out the Royal Navy would have been vulnerable to air attack by the Luftwaffe if Germany had achieved air superiority,[210] citing the sinking of Prince of Wales and Repulse in December 1941 by an attack by Japanese aircraft.[210] In late May 1941 during the successful German airborne assault which seized Crete, the Royal Navy was able to prevent attempted German seaborne landings on the coast of Crete, despite losing six ships in three days due to undisputed Luftwaffe air supremacy. Churchill later wrote that the Royal Navy’s defeat of “these practically defenceless convoys of troops across waters of which they did not possess naval command as well as that of the air is a sample of what might have happened on a gigantic scale in the North Sea and English Channel in September 1940.”[211][212] Crete was lost to German airborne troops which neither the RN nor the absent RAF could stop.

A considered view of the battle also has to take into account the vital role of the Royal Navy. It was widely acknowledged by both sides that the only way of achieving a successful invasion of the British Isles was through the establishment of naval supremacy. Given the inability of the Luftwaffe to effect real damage on the RN throughout the battle and during the Dunkirk and Norwegian campaigns, as well as the lack of surface assets in the Kriegsmarine‘s inventory, sea control of the Channel by Germany was impossible. As one of ‘the Few’, Wg Cdr H R Allen said, “It was sea power that ruled the day in 1940, and fortunately Britain had a sufficiency. The air situation was, of course, important, but by no means fundamental. Without doubt the five hundred or so section, flight and squadron commanders in Fighter Command earned their laurels. But the real victor was the Royal Navy, the Silent Service.”[213] The Luftwaffe had 1,380 bombers on 29 June 1940. By 2 November 1940, this had increased to 1,423,[214] and to 1,511 by 21 June 1941, prior to Operation Barbarossa, but showing a drop of 200 from 1,711 reported on 11 May 1940.[215][216][nb 24] 1,107 single- and 357 twin-engined daylight fighters were reported on strength prior to the battle on 29 June 1940, compared to 1,440 single- and 188 twin-engined fighters, plus 263 night fighters, on 21 June 1941.[188][215]

There is a consensus among historians that the Luftwaffe simply could not crush the RAF. Stephen Bungay described Dowding and Park’s strategy of choosing when to engage the enemy whilst maintaining a coherent force as vindicated; their leadership, and the subsequent debates about strategy and tactics, however, had created enmity among RAF senior commanders and both were sacked from their posts in the immediate aftermath of the battle.[217] All things considered, the RAF proved to be a robust and capable organisation which was to use all the modern resources available to it to the maximum advantage.[218] Richard Evans wrote:

Irrespective of whether Hitler was really set on this course, he simply lacked the resources to establish the air superiority that was the sine qua non-of a successful crossing of the English Channel. A third of the initial strength of the German air force, the Luftwaffe, had been lost in the western campaign in the spring. The Germans lacked the trained pilots, the effective fighter aircraft, and the heavy bombers that would have been needed.[219][nb 25]

The Germans launched some spectacular attacks against important British industries, but they could not destroy the British industrial potential, and made little systematic effort to do so. Hindsight does not disguise the fact the threat to Fighter Command was very real, and for the participants it seemed as if there was a narrow margin between victory and defeat. Nevertheless, even if the German attacks on the 11 Group airfields which guarded southeast England and the approaches to London had continued, the RAF could have withdrawn to the Midlands out of German fighter range and continued the battle from there.[221] The victory was as much psychological as physical. Writes Alfred Price:

The truth of the matter, borne out by the events of 18 August is more prosaic: neither by attacking the airfields, nor by attacking London, was the Luftwaffe likely to destroy Fighter Command. Given the size of the British fighter force and the general high quality of its equipment, training and morale, the Luftwaffe could have achieved no more than a Pyrrhic victory. During the action on 18 August it had cost the Luftwaffe five trained aircrew killed, wounded or taken prisoner, for each British fighter pilot killed or wounded; the ratio was similar on other days in the battle. And this ratio of 5:1 was very close to that between the number of German aircrew involved in the battle and those in Fighter Command. In other words the two sides were suffering almost the same losses in trained aircrew, in proportion to their overall strengths. In the Battle of Britain, for the first time during the Second World War, the German war machine had set itself a major task which it patently failed to achieve, and so demonstrated that it was not invincible. In stiffening the resolve of those determined to resist Hitler the battle was an important turning point in the conflict.[222]

The British victory in the Battle of Britain was achieved at a heavy cost. Total British civilian losses from July to December 1940 were 23,002 dead and 32,138 wounded, with one of the largest single raids on 19 December 1940, in which almost 3,000 civilians died. With the culmination of the concentrated daylight raids, Britain was able to rebuild its military forces and establish itself as an Allied stronghold, later serving as a base from which the Liberation of Western Europe was launched.[20]

Battle of Britain Day

Winston Churchill summed up the effect of the battle and the contribution of Fighter Command with the words, “Never in the field of human conflict was so much owed by so many to so few“.[144][223] Pilots who fought in the battle have been known as The Few ever since; at times being specially commemorated on “Battle of Britain Day”, the 15th of September. On this day in 1940, the Luftwaffe embarked on their largest bombing attack yet, forcing the engagement of the entirety of the RAF in defence of London and the South East, which resulted in a decisive British victory that proved to mark a turning point in Britain’s favour.[224][225]

Within the Commonwealth, Battle of Britain Day has been observed more usually on the third Sunday in September, and even on the 2nd Thursday in September in some areas in the British Channel Islands.

The day has been observed by many artists over the years, often with works that show the battle itself. Many Mixed Media artists have also created pieces in honor of the Battle of Britain.[226]
