Combat,
While Guderian, the father of the Panzer divisions, was nominally in control of tank production after he fell out of favor with Hitler over operation Barbarossa, as in all other areas of German design and production, Hitler had the final say.
You sure seem enamered of old Adolf's military capacities, something only the author you cite, Alan Clark, otherwise appreciates.
Louis-
Hitler was undoubtedly an evil man. As a result, I think it is extremely difficult to concede that he had certain talents. It creates the dangerous possibility that it might be used to mitigate his otherwise colossal crimes. History has to be objective though if it is to have any meaning.
Intro from "Hitler and his Generals - Military Conferences 1942-1945"
"one must grant that many of Hitler's military decisions until very near the end, were in the technical sense throughly reasonable -- more reasonable, in any case, than the usual version of events would lead one to believe. In the published transcripts that follow there are a number of examples of Hitler's decisions that are usually thought of as insane, overly confident, or based on blind emotion at best, but which were actually rooted in considerations that at least at the time seemed plausible, even when in hindsight they cannot be judged as completely objective. And as already mentioned, there were also decisions that were fundamentally correct -- even in hindsight -- and which were successful or averted disaster."
"Whatever one credits or does not credit Hitler with as a military leader, and whatever pieces of the mosaic are missing from this collection that would complete his portrait, one point should not be overlooked under any circumstances: the German Armed Forces were not defeated in WW II because Hitler led them poorly and continually handicapped his generals, nor because the clever instincts of the Fuhrer were diluted or sabotaged by this generals, who were at the very least narrow-minded if not downright evil. ...militarily the war could not have been won after 1941, and it wasn't won before 1941, despite dazzling battlefield victories."
Hitler's War - David Irving (on Stalingrad defeat): "The blame for the disaster was diverted onto Hitler. In later years memoirs were fudged by field marshals, fake diaries were concocted, guilty sentences were expunged from the OKW's war diary, and contemporary judgements on Hitler's leadership were slotted in."
