How Eagle Day became a key turning point in the Battle of Britain

August 13, 1940, is a day that will forever be etched in the history of the Second World War. On that day, Reichsmarschall Goring, head of the Luftwaffe, had every reason to be confident that he could knock out the Royal Air Force in one fell swoop, paving the way for a ground invasion of Britain.

Goring's offensive was code-named Operation Adlerangriff, or 'Eagle Attack' and the start date 'Eagle Day'. It was, however, a resounding failure.

Operation Eagle Attack

'Eagle Attack' represented the first major and concentrated attack on RAF airfields during World War 2.

The plan was to put these airfields out of action and prevent the RAF from defending the skies above the English channel in the same force they had achieved thus far. Once this had been achieved, the Luftwaffe would prevent the Royal Navy from being able to contest landings of the Heer, the German army, who would force a surrender.

The operation started badly and never recovered for the Germans. Confusion reigned over whether the operation was happening at all. Goring only gave final confirmation that the operation was on at 2 pm, well after the first bombers had taken off having failed to receive the order to abandon operations due to bad weather.

Once the operation was finally given the go-ahead, the Luftwaffe found itself harassed at every point over southern England, with RAF fighters using the 'Dowding System' to successfully intercept the raiders. The number of downed aircraft reported by the press varies, but the official figures put it at around 50.

What was The Dowding System?

The 'Dowding System' of fighter control was incredibly important to the RAF and the defense of its airfields and had been perfected by the time Eagle Attack was launched. Radar stations, assisted by observers, would acquire the raiders and feed information back to a fighter control station. Fighter controllers would then plot the raid on a board and scramble fighters to meet it.

The raids had very little effect on the day-to-day running of the target airfields or aircraft production, with all targets that were hit operational again within 24 hours. Most of the targets hit were not even RAF Fighter Command airfields, but those used by Bomber Command and Coastal Command.

Eagle Day also saw some of the first night-raids by German aircraft on cities, with a number targeted for their aircraft production facilities. Again, very few of these targets were knocked out or destroyed.

Despite the failure of Eagle Day, 'attacks would continue into early September, at which time the Luftwaffe would switch its main effort to 'morale bombing', specifically targeting London at the personal request of Hitler. This new period would be called 'The Blitz'.

Failure did, however, cause the Germans to reassess their plans to invade and caused a revision of the date of Operation Sea Lion. It was finally suspended on September 20, 1940, a full month after the start of 'Eagle Attack.'
