My great uncle, a vet, said his unit went into these camps and the army sent in black soldiers to clean them up. It really messed him up. I suspect it was one of the things that eventually led to his suicide.
I can’t even imagine. My question would probably be “why couldn’t we have gotten here sooner”? But the Soviet camps could be just as bad, as well as the forced mass starvations, African genocides, and what’s going on in countries like North Korea right now. The world prefers to keep them out of sight and mind.
