My dad served for 6 years, primarily in Germany. He would not talk about his experiences too much.
Our family physician and good friend of my parents. He also would not discuss his experiences.
My mother was from East Germany and her family helped with he resistance in Suhl. She got out with the allied troops a few days before the Russians came in (allies handed over the territory to them)
Dad passed away in '98. Mom remarried around '03. He was from the same region of Germany as my mom. He served in the German army and lost a leg below the knee at the Russian front. He discussed the war at length with me. What was most interesting was his (and my mom's) take on how Hitler gained control. Looking back, I wish that I had videoed the discussions....extremely informative and much more nuanced than what we read in history books. They both were adamant that the average German knew nothing about the concentration camps. He died 3-4 months ago at 97.
