Broszat criticized Irving for accepting the "fantastic" claims of the SS "Obergruppenführer" Karl Wolff that he did not know about the Holocaust (Irving's argument was that if Wolff did not know about it, how could Hitler?), despite the fact that Wolff was convicted of war crimes in 1963 on the basis of documentary evidence implicating him in the Holocaust. Broszat also accused Irving of seeking to generate a highly misleading impression of a conference between Hitler and the Hungarian Regent, Admiral Miklós Horthy, in April 1943 by re-arranging the words to make Hitler appear less brutally antisemitic than the original notes showed.
