The Battle of Britain took place between August and September 1940. After the success of Blitzkrieg, the evacuation of Dunkirk and the surrender of France, Britain was by herself. The Battle of Britain remains one of the most famous battles of World War Two.
At the start of the war, Germany had 4,000 aircraft compared to Britain's front-line strength of 1,660. By the time of the fall of France, the Luftwaffe (the German air force) had 3,000 planes based in north-west Europe alone including 1,400 bombers, 300 dive bombers, 800 single engine fighter planes and 240 twin engine fighter bombers. At the start of the battle, the Luftwaffe had 2,500 planes that were serviceable and in any normal day, the Luftwaffe could put up over 1,600 planes. The RAF had 1,200 planes on the eve of the battle which included 800 Spitfires and Hurricanes - but only 660 of these were serviceable. The rate of British plane production was good - the only weakness of the RAF was the fact that they lacked sufficient trained and experienced pilots. Trained pilots had been killed in the war in France and they had not been replaced.Britain had a number of advantages over the Luftwaffe. Britain had RADAR which gave us early warning of the approach of the German planes. By the Spring of 1940, fifty-one radar bases had been built around the coast of southern Britain. We also had the Royal Observer Corps (ROC) which used such basics as binoculars to do the same job. By 1940, over 1000 ROC posts had been established. British fighter planes could spend more time in the air over Kent and Sussex as we could easily land for fuel whereas the German fighters could not. German bombers could fly for longer distances than their fighter planes could cover and therefore, the bombers could not always count on fighter cover for protection. The German fighters were also limited in that they could not reload their guns if they ran out of ammunition while over Kent etc. Our fighters could. Without sufficient fighter cover, the German bombers were very open to attack from British fighter planes.The battle started on July 10th 1940 when the Luftwaffe attempted to gain control of the Straits of Dover. The aim of the Luftwaffe was to tempt the RAF out for a full-scale battle. By the end of July, the RAF had lost 150 aircraft while the Luftwaffe had lost 268. In August, the Luftwaffe started to attack Fighter Command's airfields, operation rooms and radar stations - the idea being that the RAF could be destroyed on the ground so that the Luftwaffe need not fight them in the air. Without radar the RAF would be seriously hampered in terms of early warning and the destruction of operation rooms would cut off communications between fighter bases and those at the heart of the battle controlling the movement of fighter planes. Destroyed runways would hamper the chances of a fighter plane taking off.
