My dad went over just after the Bulge and always spoke highly of the black soldiers, who he referred to as “colored guys”. He’d never been around many before and had no prejudice, it was just a descriptive term like saying “fat guy” or “a guy from New Jersey”.
Being a wiseass, I’d ask “what color was he?”
A book I suggest about the 761st is "Brothers in Arms: The Epic Story of the 761st Tank Battalion, WWII's Forgotten Heroes " by an unlikely author - Kareem Abdul Jabbar.
His father's best friend was in this unit and that is what intrigued him to research and write their story.
