Battle of Britain

The Battle of Britain (German: Luftschlacht um England) is the name given to the sustained strategic effort by the German Luftwaffe during the summer and autumn of 1940 to gain air superiority over the Royal Air Force (RAF), especially Fighter Command. The name derives from a speech made on 18 June 1940 in the House of Commons by Prime Minister Winston Churchill, "The Battle of France is over. I expect the Battle of Britain is about to begin..."

Had it been successful, the planned amphibious and airborne forces landings in Britain of Operation Sealion would have followed. The Battle of Britain was the first major campaign to be fought entirely by air forces. It was the largest and most sustained bombing campaign attempted up until that date. The failure of Nazi Germany to destroy Britain's air defence or to break British morale is considered both its first major defeat and a crucial turning point in the war.
