Bill T. is a member of the Old Bastards. He is one of the few who is a veteran of WWII. He tells this story with great humor. It is one he would tell when old Army buddies would get together at his home. He would wait until his late wife was in earshot.
There is some truth and maybe a little bit of a stretch.
He tells that he was dropped into France 10 days prior to D-Day. As a member of an advanced party he had a great number of duties. The one he tells that used to rile his wife was this one. One of his primary duties was to help the French women learn how to greet and treat the US soldiers. He did indicate that he showed them how.
Whenever his wife heard him tell it, she would throw something at him. I don't think he has any scars from it. It is funnier when he tells it.
