Just saw this note (now two years old). XXX1: if your friend is still with us and has any interesting stories to tell, please interview him. Get as many stories as you can ... anything about Patton is fascinating -- from North Africa to Sicily to Germany. Please see Heroic Tale of a Tail Gunner for a story I just wrote to preserve this vital part of our history. Don't let this opportunity pass if he is still alive -- we won't have many WWII vets left soon.
P.S. As a midshipman being trained in amphibious assault in 1967, I served on the U.S.S. Monrovia, which was Patton's Command Ship for the Sicily invasion -- perhaps your uncle's friend debarked from that ship?
