I recently heard an anecdote about my deceased grandfather. He was a WWII U.S. Army veteran. The story goes that he was an MP posted to direct traffic when suddenly the jeep that dropped him off came back and yelled for him to get in because a German tank column was coming up the road behind them.
This sounds like the "Battle of the Bulge" to me, but I'm not sure where he was stationed. And I never got the chance to talk to him about it. I know he started the war stationed in the U.S. and ended up in Berlin after. I have some of his medals and citations, but not much else. I was hoping there might be a book or online source where I could look for his name to find out more info.
r/AskHistorians has a guide on finding family members' military records here. Be warned; in the case of the United States, a large portion of Army and Air Force Official Military Personnel Files for the period 1912-1960 were destroyed in a fire at the National Personnel Records Center in St. Louis in 1973. If anything can be found at all, it may be damaged or incomplete.
