Dogfight tells the story of Australians and New Zealanders in one of the Second World War's defining and most memorable campaigns. From July until October 1940, the German air force (the Luftwaffe) sought aerial supremacy in skies over England as a prerequisite for an invasion of Britain (Operation Sealion). The ensuing conflict of Luftwaffe and RAF aircraft in the long summer of 1940 became forever known as the Battle of Britain.
