Based on the responses in the following thread links, I went ahead and transcribed some paragraphs from Beevor’s latest work:
In his latest book on the Battle of the Bulge Ardennes 1944, Antony Beevor writes:
Tensions between the Waffen-SS and the German army were growing because of Hitler’s insistence on saving SS formations in a retreat while ordinary (Heer) divisions were left to fight on as a rearguard
…
“There were many comments”’ acknowledged General Warlimont, “to the effect that the SS no longer considered itself a member of the Wehrmacht but had its own organization.” Sepp Dietrich wanted his Sixth Panzer Army to be designated an SS panzer army, but this was denied because he had non-SS formations in his command. Dietrich even refused to have General der Artillerie Kruse as his chief artillery officer because he was not a member of the SS. Manteuffel, like many others, had little respect for Dietrich’s generalship. He thought that the Sixth Panzer Army “was not commanded as one formation, and that its component parts did not fight with the same sense of duty as the Army divisions”. Dietrich was regarded as a bad joke by senior army officers.Oberstleutnant von der Heyte was even more scathing, after meeting (Dietrich) to discuss his parachute drop in front of the Sixth Panzer Army. He said that Dietrich liked to pose as “a people’s general”, but he was “a conceited, reckless military leader with the knowledge and abilities of a good sergeant. He has not moral scruples.” Heyte, although a German nationalist, detested the Nazis. (pg. 88)
