Churchill's failure to support Harris post-Dresden was unforgivable. Harris was a single-minded fighting man with one objective: destroy Germany, Churchill was a career politician. But what a politician Harris could have been!
Although dealt with ad infinitum in previous_PPrune, the usual myths still reappear. With no wish to enter into debates to cover old ground:
I) Primary purpose of the raids on Dresden, Hiroshima and Nagasaki was to demonstrate Western air power to the Soviets. Military significance was immaterial.
2) Re: the war on the Eastern Front, the Red Army needed no assistance from the West to stop the Wehrmacht at Moscow, minimal assistance provided by the West prior to victory at Stalingrad. If Britain fell in 1940 then the Red Army still rolls into Berlin, perhaps 1947, and then onto Calais. Why? A clue: in 1942, T34 tank production was c12,000, total German tank production c6,000.
Perhaps the greatest achievement of Bomber Command during 1939 - 1945 was to ensure that the Red Army advanced no further after May 1945?
