Bombing of Cologne in World War II

The German city of Cologne was bombed in 262 separate air raids by the Allies during World War II, all by the Royal Air Force (RAF). A total of 34,711 long tons of bombs were dropped on the city by the RAF. 20,000 civilians died during the war in Cologne due to aerial bombardments.

While air raid alarms had gone off in the winter/spring of 1940 as British bombers passed overhead, the first bombing took place on 12 May 1940. The 30/31 May 1942 attack on Cologne was the first 1,000 bomber raid.
