Blitzkrieg
The Blitz refers to the German bombing of Britain, particularly London, during World War II, which destroyed over a million homes and killed over 40,000 people. It was supposed to quickly destroy industry and morale to make the British pressure the government to end the war. The Blitz was in response to the British bombing of German cities by the Royal Air Force. The Blitz began in September 1940 and continued until May 1941.
