I had relatives that were at the Battle of the Bulge, but one fellow I worked with was a captain in the Army during the Bulge battle. I never served in the military, and he would often talk about his experiences during the war. As long as I sat there and listened to his stories, I was fine. But if I said anything resembling an opinion, etc, he would get belligerent and say, 'unless you have seen a bullet fired in anger in your direction, shut up.'
After the Germans started killing captured Allies, he told me that he ordered his men to NOT take any SS as prisoners. He indicated they were all shot. He himself was injured and had a metal plate in his head. He had quite a few stories that were interesting.
