The siege, and Battle of Knoxville, Tennessee

Andersonville, which rings a distant bell, is probably the prison I had in mind.

I have some recollection that Wirz, like others executed after wars by victors, might not have deserved his fate, but I can’t recall why.

I have heard that as well, scapegoats are all too common in Human warfare. Wirz being the commandant, particularly if he were foreign would make the choice easy. Brutal stuff, but I’m looking through eyes of today, and not those of that time and level of consciousness.
