Overview

The Battle of Britain was a military campaign of the Second World War, in which the Royal Air Force (RAF) and the Fleet Air Arm (FAA) of the Royal Navy defended the United Kingdom against large-scale attacks by Nazi Germany's air force, the Luftwaffe. It was the first major military campaign fought entirely by air forces. It takes its name from the speech given by Prime Minister Winston Churchill to the House of Commons on 18 June, 1940: "What General Weygand called the 'Battle of France' is over. I expect that the Battle of Britain is about to begin."

Significance

The Battle of Britain was the first major military campaign fought entirely by air forces, marking a significant shift in how modern warfare could be conducted. The Royal Air Force and the Fleet Air Arm defended the United Kingdom against large-scale Luftwaffe attacks, with German forces fielding approximately 2,550 aircraft against a British force of roughly 1,963. German casualties exceeded British losses, with 2,585 German aircraft or aircrew lost against 1,542 on the British side. The campaign took its name from Prime Minister Winston Churchill's address to the House of Commons on 18 June 1940, in which he declared the Battle of France over and anticipated the coming aerial struggle for Britain. The defense of British airspace denied Germany the air superiority that would have been prerequisite to any cross-channel invasion, preserving the United Kingdom as an active belligerent in the wider European conflict.
