First Victories in the Battle of Britain. The first fighter actions of the Battle of Britain took place over southeastern England during the late summer of 1940. On July 4th, in a series of isolated fights, one Hurricane and two Spitfires were shot down by Bf109's. A similar scenario was repeated three days later. The Bf109E's of JG51 shot down five Spitfires of No. 64 and 65 squadrons of the RAF, for no own losses. This was a promising start for the Luftwaffe, in a campaign that would prove to be their most bitter loss so far.
