My wife's s dad was combat medic during WWll. He was in Normandy and the Battle of the Bulge. He was seriously messed up in the head when he cam home and spent several weeks in a Army hospital undergoing Electro shock "therapy"
before returning home to his family. He would not talk about his time in the war to anyone. My son did a search of his military records and we found out about his experiences . I can only imagine the things he saw and did.
