My father-in-law, who is 91, arrived in France two weeks after D-Day.
He walked and rode across Europe with the US Army, making it to the concentration camps in Germany (my wife once asked him how often he took a bath or brushed his teeth and he just rolled his eyes).
He remembers sleeping in a castle at one point.
For some reason, I'm the only family member he talks to about the events of that time. Some are funny and some are incredibly sad.
My own father was younger and he lived in Ireland, which was neutral. During WW II, my Dad remember the American GIs sneaking over the border (from Northern Ireland) into The Free State because the pubs were supposed to be better.
After the war, my Dad actually signed up for a trial period with the RAF (as a mechanic), but by the time the trial period was over, he and Mom had decided to emigrate to Canada.
Here's a recent shot of my WW II-vet father-in-law (and my mother-in-law). Married 60+ years.
When he returned from the war, he went back to Bucknell to finish his degree. But he flunked a Statistics class so he had to retake it. When he toke Statistics the second time, he sat next to a good-looking girl who he ended up marrying.
