A strategic bombing campaign was waged by RAF Bomber Command against Nazi Germany and other Axis powers in Europe during the Second World War.
After suffering heavy losses attempting daylight bombing raids over the Heligoland islands in the North Sea and over France during the first half of 1940, Bomber Command had largely withdrawn its aircraft from daylight attacks.
[1][2] Bomber Command, however, was still willing to risk aircraft to attack targets in daylight on occasion.
These were usually targets that required highly precise delivery of bombs, such as warships or small factories.
[3] These missions were various fighter sweeps over northern France and Belgium conducted to engage the Luftwaffe.
