Rommel was a prick. Not too many GIs would have liked him. They try to make him out to be the German Patton. Not even close. He was a disciplinarian and a stickler for order.
The Germans I met who were in his armies were pretty “meh” about serving under him. Not so with Patton. Yeah, they had to wear ties. But he was bold and he won.
I wonder though, given how Rommel felt about Hitler, if he might have sabotaged the Normandy defense to make it easier for the Allies.
You would have expected with Rommel’s reputation, the German defense on D-Day would have been more effective.
