They were treated badly and I can't believe just one bit of unbiased conversation cannot be had.
I think the basic problem was overcrowding on both sides, which was brought about by the Federal decision to stop prisoner exchanges.
I blame the South's refusal to employ furlough.
Prison populations grew slowly until an exchange cartel was reached in 1862, then they fell sharply as prisoners were exchanged. After the North stopped exchanging prisoners in 1863,...
Because of the south's uncooperation.
...the prison population boomed. New prisons had to be built, and existing ones had more prisoners than they were designed for. The big death rates occurred after the exchanges were stopped.
And they were stopped because the south wouldn't employ furlough.
Overcrowding lead to rapid spreading of disease among the prisoners. The medicines of the time were probably not good enough to handle some of the diseases that ranged through the prisons, e.g., small pox, etc. Insufficient food didn't help either. Overcrowding also stretched the already limited food supply of the South. A report to the Confederate Congress on the Confederate food situation for the population in general noted that most families of soldiers had not had any meat to eat in six months. A large part of the Southern population was involved with the war and no longer available for food production. That was listed in the Southern papers as one of the arguments against using slaves in the army. The food supply would have gone to pot. The fact that there were roughly comparable overall death rates in Northern and Southern prisons suggests to me that there were common factors at work. Disease being the main killer on both sides, I suspect overcrowding with some effect for skimpy and inappropriate food.
Elmira was in the cold so I'm sure part of it's high death rate was due to that. When the south could not feed the POWs, they should've been released. To not do so was murder being that they died at a 39% rate.
Per your arguement, when the Union could not feed & CLOTHE the POWs, they should've been released. It was murder right?
