Battle of Berlin (RAF campaign)
The Battle of Berlin (November 1943 to March 1944) was a series of attacks on Berlin by RAF Bomber Command along with raids on other German cities to keep German defences dispersed. Air Chief Marshal Sir Arthur Harris, AOC-in-C (Air Officer Commanding-in-Chief) Bomber Command, believed that "We can wreck Berlin from end to end if the USAAF come in with us. It will cost us between 400 and 500 aircraft. It will cost Germany the war".
