No point in crying over history. One corrects, and moves on.

I remember just after the war (WW2), I was at a camp where many GI's were coming to be re-assigned or demobilized.
One Black soldier came (don't know his unit but probably auxilliary). He was assigned to an empty barracks where he was the sole occupant. He was given his meals in a small building near the kitchen facilities. He didn't participate in any of our duties (make-work stuff, we were just passing through).
The word was that he was outside our vision.
I was re-assigned rather quickly so I never learned any more about his situation or disposition.
