"Disqualified" I don't think so. Some of the methods imployed are certainly problematic but then the same can be said of Dupuy or Glantz. In the former case it usually people trying to read more into his work than is there though. Glantz has also been accused of not making enough use of German records.
And you knew it? And still you came up with that hoax and try to pass it as a reference text to us? You just tried to deceive us with "make believe" information. Next time you can send us a link from youtube with an episode of Combat!
Glantz use German records, I have a book of his filled with them, read the bibliography (and what's the matter, you think German records are at fault, didn't you?). And Dupuy is certainly a respected author with even an Institute to study such things. Of course everybody present problems but it's the degree of them: Bonn simply made a outstanding incompetent work.
