Not all where cowed down by Hitler!
In March 1945 he was G.O.C. 2nd Army in Sopot, Gydnia and Danzig areas. His fellow-cavalryman Captain Gerhard Boldt has left a brilliant description of a meeting between Hitler and von Sauken in the Chancellory in March 1945. 'Slim, elegant, his left hand resting casually on his cavalry sabre, von Sauken saluted and gave a slight bow. This was three outrages at once. He had not given the Nazi salute with raised arm and the words "Heil Hitler", as had been regulation since 20 July 1944; he had not surrendered his weapon on entering the operations room; and he had kept his monocle in his eye when saluting Hitler....' Guderian and Bormann, who were present, seemed turned to stone, but Hitler merely asked Guderian to brief von Sauken on conditions in East Prussia and the Danzig area, where he was to take over 2nd Army Group. Hitler then told the General that in the Danzig area he would have to accept the authority of Gauleiter Forster. Von Sauken stiffened and, still with eyeglass in place struck the marble table with the flat of his hand and said: "I have no intention, Herr Hitler, of placing myself under the orders of a Gauleiter!" Boldt adds: 'One could have heard a pin drop on the carpet. It seems to me that Hitler shrank physically from the General's words. His face looked even more waxen, his body more bowed than ever....'
Guderian and Bormann then tried to persuade von Sauken to be reasonable, but he would only reply, "I have no intention whatsoever of doing so...." Hitler, who seemed at last to have met his match in the matter of gazes, finally said in a weak voice: "All right, Sauken, keep the command to yourself." After a few more minutes of discussion von Sauken left 'with the merest hint of a bow'. Hitler did not shake his hand.
Guderian had a high opinion of von Sauken, whose abilities he thought 'outstanding'. He records, in his book 'Panzer Leader', that in Eastern Germany in 1945 'Generals Nehring and von Sauken performed taskes of military viruosity during those days that only the pen of a new Xenophon could adequately describe.'
