That sucks, big time. Where did he serve, if I may ask?
I actually don't know. My grandfather was so ashamed of his father that he burnt everything including the uniforms, records, medals, etc. I'd have to ask him, I'm sure he would know. However, he doesn't really associate himself with my family anymore. Which sucks, but... what are you going to do? Some people just don't care for anyone but themselves. All I can think of is that my great grandfather was killed during the German counter-aggression into France after liberation. There were some Fallschirmjaeger drop missions during that time, especially near Carentan.
My great grandfather was actually a very decorated war hero after WWI. He rose to the rank of Colonel after "The Great War."
