Thanks for the followup. He never mentioned anything to me about anything related to his Army days. I just assumed he just didn't want to talk about them.
I've just been curious about his experiences the last few years while I've been retired and working on family genealogy.Unfortunately, the ones in the family that knew are all now gone.All I have to work on is a few postcards he sent to Grandma and his Army records.Records seem to be scarce after the fire at Jefferson Barracks, St.Louis in the early 1970's.
On one of his postcards he mentioned "I've seen things over here I don't want to ever see again".Of course, that could mean anything.My cousin told me that one day when she was a little girl, she was looking at some old photos and found one of him and another soldier standing in front of a small tent - rifles at ready.She asked him who the other man was and he told her his name & where he was from.She didn't remember all the particulars, but when she asked if he still kept in touch with the other soldier, he said "no, he was killed on a raft crossing a river".
