In July 1940, the German Luftwaffe began intense aerial attacks on British airfields and ports. The British Royal Air Force, outnumbered but with better planes and pilots, shot down so many aircraft that the Germans were forced to give up daytime attacks. In September 1940, Reich Marshal Hermann Goering took command of the air assaults and his Luftwaffe switched to nightime attacks. From September 7, 1940, through May 10, 1940, the Luftwaffe bombed London nearly in every night. These raids became known as the "London Blitz."
