Just read some Chapters in Bomber Offensive from 1947(by Sir Arthur Harris), and find his that his arguments for the Airwar is quite god.
Actually did the Bombings of Hamburg d. 27.-28. juli really scare the Germans. Albert Spear reported to Hitler that six more Bombing raids like the one in Hamburg on further German cities, would drastically shorten the war.
But as we know today did the Allied not perform many of those mega bombing
raids, who had the same effect as the one against Hamburg.
