The day began with a feint in the east with the real attack coming in over the west country. A substantial raid developed on Portland and Weymouth with well over 100 aircraft involved. Several squadrons intercepted. Dogfights ensued. Over 70 bombs were dropped and damage was done to property and the railway line. This was the biggest battle so far during the Battle of Britain.
Meanwhile, in the east, there was continuous activity around Dover and the Straits. 74 Squadron flew no less than four sorties from Manston. Several more squadrons were engaged before hostilities ended. It was indeed a busy day for Manston. Losses were heavy on both sides. Over 30 German aircraft were shot down in return for losses to the RAF of 27 aircraft. There had been much fighter to fighter combat, hence the losses.
Adler Tag had now been set for August 13th.
19 Squadron Operational Record Book – 11 August
New Spitfire equipped with 2 cannon and 4 Browning Guns delivered today. Is slightly overweight but in the general opinion is a step in the right direction. Possibly another step in the same direction would be the re-equipping with the old eight-gun machines.
Reported Casualties (RAF Campaign Diary 11th August 1940):
