Thanks for posting all these stories and jokes! My grandfather landed at Utah beach on D-Day plus 94 as part of the 94th Infantry Division. Sadly, he died after the war before my dad was old enough to understand or remember any of his stories, though other family members have given some second hand tellings.
My Uncle survived the Dunkirk evacuation, he never talked about it openly and I was too young to know him properly. He later joined the commandos and again didn't talk much about his experiences. The one story I hear about was something that happened after the war, he was in a cinema queue with my aunt and there were a couple of thugs being tough and noisy who decided they didn't want to wait in line and headed for the front of the queue. One of them was waving a knife in peoples faces challenging anyone to object, then he got to my uncle. My uncle's recollection of what happened was that the knife thug came near him, my uncle blinked and found the thug on the ground screaming, and the rest of the queue were cheering, turns out he broke the guys arm when he waved the knife in my uncles face. I guess his old training just kicked in, the police showed up and took the thug away, his pal had done a runner. R.I.P. Bill MacGregor, I wish I knew you better.
