A major campaign of the early part of World War II, the Battle of Britain is the name commonly given to the attempt by the German Luftwaffe to gain air superiority over the Royal Air Force (RAF), before a planned sea and airborne invasion of Britain (Operation Sealion). Neither Hitler nor the German Wehrmacht believed it possible to carry out a successful amphibious assault on the British Isles until the RAF had been neutralised. Secondary objectives were to destroy aircraft production and ground infrastructure, as well as terrorising the British people with the intent of intimidating them into seeking an armistice or surrender.
That was the whole plan of Battle of Britain to destroy the RAF and the aircraft production and ground infra. But Hitler changed it all to terror bombing and that is the main reason why the RAF survived and destroyed most of the Lufftwaffe. If Hitler would have kept to destroying infra. and airplane prod. the Battle of Britain would have been won by the Germans.
