One thing that is often levied agaionst the bombing campaigns is the
fact that German production increased as the war came to an end (at
least until the last few days when industry was being overrun).
But, the reality is not so clear. WE need to realize that Germany
did not go to a full wartime production footing until 1943-44, and as
such, there wsa a great deal of "fat" in the industry that could be
cut-- in other words, while bombing did not stop the increase of
production, that was also due to the fact that the germans were only
beginning to introduce the wartime production measures that had been
par for the course in the U.S. and England from 1939 (england) and
1941 (US) on.
The German industrial expansion was dramatically slowed by the
bombing campaign, as many, many books I have on German air projects
contian notes like " The project was abandoned after the
prototype/engines/airframe/fill in the blank was destroyed by U.s.
bombing.
