Rommel committed suicide in October 44, two months before the Bulge. He had been seriously wounded in July 44 and was essentially not in active command after that. Rommel was given a cyanide capsule as an alternative to a kanagroo court trial in front of a People’s Court.
Good point. He may have not contributed to the offensive. Apparently, he had a skull fracture. But in a pinch, he might have been brought into the action.
