Uh, a not insignificant number
were "put to death," summarily shot while trying to escape, or even for so much as stepping over a demarcated line, and in one instance, several were shot for sitting down when told not to!
Additionally, thousands of southern prisioners died unnecessarily in the brutal and horrid conditions of the camps.
Please read further into the history of your own country before you expound on it.
As for the fate of northern prisioners in southern camps, they fared even worse. One of my forebears died in Andersonville. Conditions there rivaled the Nazi death camps, though more from lack of resources than from an intentional policy. Still, thousands slowly and painfully starved to death.
As a kid, I saw pictures of survivors of Andersonville who were living skeletons. I'm sure most of them didn't survive for long. The image of those pics have stuck with me down through the years.
And, finally, the commandant of Andersonville wasn't
just court-marshaled. He was
executed, hung and left writhing and choking while thousands watched.
Apparently you didn't know this, either. :'(
Some Andersonville "survivors,' here ya' go:
