After defeating France in June 1940, Hitler assumed Britain would sue for peace but ordered his armed forces to prepare for invasion. Hermann Goering assured him that a sustained air assault would destroy the RAF, winning the air superiority needed.

July 1940 saw German planes target shipping in the Channel, drawing the RAF into combat, before radar stations, communications centres and airfields faced round-the-clock bombing in August. The battle reached a climax with attacks on London in September.
