Aerial bombing of cities - Wikipedia, the free encyclopedia

While Germany refrained from aerial bombing of British cities after the British declaration of war on Germany in September 1939, Britain started aerial bombing of Germany, officially focusing on military and industrial targets, on the night of 15/16 May with 78 bombers against oil targets, 9 against steelworks and 9 against marshaling yards.[8] Oil remained the main British objective until the summer of 1941.<br />
After the German victory in the Battle of France, the Luftwaffe turned its attention to the United Kingdom. The scale of the attack increased greatly in July, with 258 civilians killed, and again in August with 1,075 dead.[9] During the night of 28/29 August, British bombers raided targets in and around Greater Berlin for the first time, in response to the bombing of London by the Luftwaffe. On the 7th September the Luftwaffe began massed attacks on London in retaliation.
