This book tells the story of Australians and New Zealanders in one of the Second World War’s defining and most memorable campaigns. From 9 July until 31 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.
