...and, as always, no-one has mentioned the 790 aircrew of Bomber Command who died during the same period. While Fighter Command defended against the Luftwaffe during the day, the aircrew of Bomber Command went out at night to attack the German invasion barges in the cross channel ports...the Germans were forced to remove these from range before the official end of the BoB (don't believe the film). As Churchill said at the time...the fighter is our means of salvation, but the Bomber is our sole means of victory. Don't forget the "Battle of the Barges" either!
The bombers did play major part in the air war as well, as the 2 Group and Coastal Blenheim did do daylight attacks on airfields across the channel. Though they where soon ended after a couple of squadrons were wiped out, they forced the Germans for keep at least one fifth of their fighter force over France doing standing patrols during daylight hours throughout the whole battle.
