Hitler's Directive for the Conduct of War Against England

On 1 August 1940 Hitler issued his Directive No 17, For the Conduct of Air and Naval Warfare Against England. In summary it said:

• Employ all forces available to eliminate the British air force as soon as possible
• Once temporary or local air superiority is achieved, operations will continue against ports
• Air operations against hostile naval and merchant ships will be considered a secondary mission
• The intensified air offensive will be conducted so that adequately strong air forces can be made available whenever required to support naval operations against favourable fleeting targets

Eagle Attack

On 2 August 1940 the Luftwaffe General Staff issued the plan for the destruction of the RAF, starting the campaign for the Battle of Britain. Their plan for Adlerangrif or "Eagle Attack" consisted of three phases:

Phase One

First 5 days: attacks made a semicircle starting in the west and proceeding south and then east, within a 90 to 60 mile radius of London

Phase Two

Next 3 days: radius from London reduced to between 60 and 30 miles

Phase Three

Final 5 days: attacks concentrated within a 30 mile radius centred on London


In addition to the task of defeating the RAF, the German Combined Staffs had issued a directive in July from Field Marshal Keitel stipulating:

"The German lack of command of the sea could be substituted by supremacy in the air"

It was recognised that permanent air supremacy was impossible without the occupation by land forces because many of the British air bases and supporting factories were beyond the range that Luftwaffe bombers could operate with fighter escorts. But it was thought that temporary air supremacy over the invasion area would be possible. This was considered sufficient to allow Operation Sea Lion (the invasion of England) to proceed as planned.

The Luftwaffe were confident in their believe that they could achieve:

"The destruction of RAF Fighter Command in the south, would take four days"

Not all of the Luftwaffe leadership was the General Staff that Alderangrif was the correct approach. The two Luftlotten commanders, Sperrle and Kesselring, both felt that RAF Fighter Command should be decisively weakened through night attacks before beginning any significant daylight operations.

These views were over-ruled by Goering who believed that Fighter Command had already been substantially weakened. Goering was slowly beginning to take more and more control of Luftwaffe operations.

PHASE ONE of Eagle Attack

On 6 August 1940 Goering set 10 August as the start date for Eagle Attack but bad weather postponed it until 13 August. On the 13th marginal weather resulted in the cancellation of some missions and sporadic  results from others. Instead of focussing on Fighter Command, target types were many and varied, including: Bomber Command airfields, Fighter Command airfields, Coastal Command stations, channel shipping, aircraft factories and at least nine manufacturing cities.

There was little other objective other than to "test the British defences."

Throughout Phase One, through to the 18 August, attacks were directed against Fighter Command but generally only limited damage was inflicted with most facilities back in service within hours.

Despite having the objective to reduce the effectiveness of Fighter Command, only limited effort was directed against Fighter Command bases, facilities and command and control capabilities.

Goering's Reorganisation after Phase One

The Luftwaffe believed it was sufficient to draw up the British fighters to kill them in the air and a German intelligence report on the 18 August suggested that it was working:

"Estimated that the British had lost 770 fighters in the period from 1st July to 16th August and that only 300 were still operational"

In reality 214 British fighters had been destroyed, 71 damaged in combat and more than 600 were still operational.

At the end of Phase One, Goering decided to withdraw Ju87s from the Battle because of their excessive losses and he needed to conserve them for support of invasion forces. Bf110s had suffered similarly high losses but Goering refused to withdraw them, instead he directed Bf109s to escort them as well as bombers.

Despite the Bf109s accounting for the majority of RAF kills, Goering would persistently blame the Bf109 pilots for lack of aggression and this led to some senior fighter unit commanders being replaced.

Goering also decided there was little value to making any further attacks of British radar installations.

PHASE TWO of Eagle Attack

Phase Two did not immediately follow the first phase because of reorganisation or additional fighter forces in the Pas de Calais and because of bad weather. After a five day delay the offensive resumed on 24 August. The Luftwaffe concentrated its attacks on Manston, Hornchurch and North Weald.

New tactics were used by both sides. The Luftwaffe used fewer bombers and more fighters in their formations because of the continued reluctance of the British to do battle with the German fighters. Park had ordered his pilots to accept combat with German fighters only if Fighter Command sector airfields were threatened.

For the duration of Phase Two, 24 August to 6 September, the RAF lost 273 fighters in combat plus 49 damaged. The Luftwaffe lost 308 fighters and bombers with 62 damaged.

Six out of seven sector airfields were extensively damaged and the telecommunications links to and from the operations blocks had proved especially vulnerable.

The German strategy of concentrating on attacking Fighter Command airfields was working, it was forcing the RAF fighters into combat. The higher concentration of fighters in German raids reduced the edge that Fighter Command had previously had.

The Luftwaffe could afford to trade Bf109s one for one with Spitfires and Hurricanes.

Fighter Command was Facing Destruction by the end of Phase Two

According to Dowding, "The rate of loss was so heavy that fresh squadrons became worn out before convalescing squadrons were ready to take their place."

Dwindling Reserves

Between 8 August and 6 September, 657 British fighters had been lost. By using replacement aircraft from repairs and storage, Fighter Command had managed to keep frontline strength to about the same levels as were available at the end of July - until 1 September.

Reserves had dwindled from 518 Spitfires and Hurricanes on 6 July to only 292 by 7 September.

Disappointing Production

In the last week of August, only 91 Spitfires and Hurricanes were produced while losses reached 137 destroyed and 11 seriously damaged.

On the Verge of Destruction

Fighter Command estimated that reserves would be exhausted in three weeks followed by the steady depletion of frontline squadrons. This would be accelerated if the Luftwaffe could successfully know out critical production facilities.

Critical Shortage of Pilots

In Phase One of the campaign (8 to 18 August) the RAF lost 154 pilots (killed, seriously wounded or missing) but only 63 new fighter pilots had come through from the training schools.

During August the combat strength of Fighter Command fell by almost a third from 1,434 to 1,023. The squadron average fell from 26 to 16 operational pilots.

In July and August, roughly a quarter of the squadron leaders and a third of the flight leaders had been killed or removed from flying due to injuries.

Experienced pilots made up less than half of Fighter Command's strength, the remainder having less than 20 hours flying time on fighters.

Stress levels were high and it was not uncommon for pilots to fly three or four sorties a day.

Eagle Attack Nearly Worked

The RAF was faced with the real possibility of withdrawing the depleted and exhausted 11 Group to bases north of London.

Goering's Eagle Attack was close to success. The Luftwaffe had within its grasp the possibility of achieving air superiority over the landing grounds of Operation Sea Lion, the German invasion of England.

Luftwaffe's Change in Strategy

From the Luftwaffe's point of view, losses were very heavy and they had failed to tempt the RAF up in sufficient numbers to allow the German fighters to deliver the decisive blow.

The idea of attacking London was gaining traction by the end of August.

The German High Command had set 15 September as the original date for the invasion but by the beginning of September it was delayed until 21 September because the Luftwaffe had not neutralised the threat from the British Navy and RAF to the invasion forces.

On 3 September Goering told Kesselring and Sperrle that there was no chance of destroying the English fighters on the ground and the RAF's last reserves would have to be forced into the air.

His idea was that if the British were heavily defending their airfields, then they would defend even more vigorously their capital. Since London was within the range of the Bf109, the Luftwaffe could more easily concentrate their fighter forces for the kill.

Sperrle strongly disagreed with Goering's plan to attack London. He felt that the British forces were too strong and that they too could concentrate all the their fighters over London. He favoured continued attacks on the airfields.

German intelligence reports suggested that British aircraft serviceability was as low as 100 at the end of August. In fact the operational strength stood at 672 on 23 August.

Hitler had forbidden attacks on London but the British had launched several attacks on Berlin in response to an accidental bombing of parts of London on 24 August. Fearing for his own popularity, Hitler agreed on 31 August to reprisal attacks on London.

PHASE THREE of Eagle Attack

On 7 September, Phase Three started with 650 bombers and over 1,000 attacking London docks by day. Substantial damage was inflicted on London but Fighter Command, from 7 September onwards, had been saved from defeat on the ground. However, it was still possible that the RAF could be defeated in the air above London.

From 11 to 14 September, London was attack by two major attacks (200+ bombers) and two minor attacks by day as well as attacks every night. Additional day raids were also carried out on Southampton (twice), Portland, Brighton, Eastbourne, Canterbury, Great Yarmouth and Norwich presumably to soften up the defences of these cities in preparation for invasion. But instead, the Luftwaffe would almost certainly have been better targeting 11 Group airfields.

Luftwaffe bombers losses were high and the bomber commanders were successful in getting Goering to order that the first role of the German fighters was to protect the bombers and not attack the enemy, but his stated objective was to draw up fighters so they could be destroyed. The whole purpose of attacking London in the first place would seem to have been lost.

The respite experienced by RAF airfields allowed the first break in over ten days for the pilots of 11 Group. Fighter Command had been in a state of near exhaustion but a new vigour resulted and was to prove decisive in the air battles on 15 September, they day that is now celebrated as Battle of Britain Day.

The Decisive Day - 15 September 1940

The Luftwaffe High Command fully expected the missions scheduled for 15 September to be the decisive blow. From Hitler down, the German leadership believed that Fighter Command had been broken in spirit and material. RAF resistance to attacks on 11 and 14 September had been slight (owing to errors in coordinating intercepts).

Attacks against London on 15 September involved 300 bombers and 1,000 fighters with another raid  of 30 against Portland and Southampton aircraft works.

With the support of 12 Group, Fighter Command met the raid with 170 Spitfires and Hurricanes operating from bases close to London which were not under attack.

Fighter Command downed 58 and damaged 25 German aircraft including 26 fighters lost and 8 damaged. Psychologically, the blow to the Luftwaffe was devastating.

British superiority on the 15 September was most likely to have benefited from the proximity of their airfields to the Battle, the freshness of the crews, the fact the airfields had not been attacked for the two days previous and the fact there was no diversionary raid.

German attacks continue in attempts to wear down the enemy but none with the strength launched on the 15 September.

Despite their continuing attacks, the Luftwaffe saw no evidence that the RAF was getting weaker but was suffering terrible losses.

Eventually raids would be restricted to the hours of darkness and Operation Sea Lion was indefinitely postponed. In the Spring of 1941, Hitler turned his attentions towards Russia and the Luftwaffe units that had been bombing England were re-deployed to the Eastern Front.

Britain can be grateful to more than just Churchill's Few

Fighter Command, particularly Dowding and Park but also all the pilots and ground crew, had played their part well and were well deserved recipients of the "gratitude of every home in our Island."

But Britain should also be grateful to some of those "in the abodes of the guilty" (as Churchill described the Germans):

had they attacked airfields by night prior to attacking them by day, 

had they attacked the airfields for longer, 

had they continued to attack Britain's radar installations, 

had Goering allowed his fighters to engage the British fighters instead of protecting his bombers, 

had Goering continued to attack airfields whilst he attacked London

had Hitler followed his instinct and prevented attacks on London 

and focussed on air-supremacy over his landing grounds

then the Luftwaffe may have won the Battle of Britain and Hitler may have invaded England.
