The bombing campaign conducted against Germany and German-occupied Europe in the Second World War was, and remains, one of the most controversial operations of the entire war. Much of Bomber Command's effort was what was defined as 'area' bombing, in which whole cities or districts were targeted. This strategy was so successful it almost brought Germany to the point of collapse until Churchill, worried about the devastation it was causing and the number of Arthur Harris' despatches explain in great detail the success of his methods which, if given full reign, may have brought the war to a speedier conclusion but would have meant even more German casualties.
