My father participated in the liberation of the Nordhausen concentration camp. He has a photo album of the camp. Needless to say the photos are gruesome.
My dad was also involved with the liberation forces, advance team. He did not like to speak of those experiences. He would usually tell us the "funnier" parts of war and our troops. Our mom told us one, tho. He saw the "gas shower rooms", and found a container filled with teeth extracted from prisoners, all containing gold fillings.
In early 70s, my brother and I were watching "Soylent Green" on the TV. So out of character for my dad, tears were flooding his eyes, as he near begged us to turn off the movie. We didn't know why, we didn't ask why. We turned the tv off, and told him how much we loved him.
The things we remember.
