Where was the prisoner of war camp in the Civil War?

Answer 1

Assuming you mean the American Civil War:

Andersonville - the most famous. A Confederate prisoner of War Camp for Federal troops. It's head warden Henry Wirz a brigadier general, was the man executed after the War by the Federals, though questions of whether or not the Union was right to execute him continue to this day.

Libby Prison - a Confederate prisoner of War Camp for Federal troops that gained a reputation as being one of the most harsh prisoner of war camps in the South.

Elmira Prison - a Federal prisoner of War Camp for Confederate troops gained a reputation for neglecting its prisoners. Of 12,123 Confederate Prisoners 2,963 died of malnutrition, prolonged exposure to winter conditions and disease cause by poor sanitary conditions and the lack of medical facilities. Nobody was held accountable for the neglect.

Camp Douglas - a Federal prisoner of War Camp for Confederate troops that, similarly to Elmira, gained a reputation for neglecting its prisoners. More than 6,000 Confederate prisoners died for disease, starvation and prolonged exposure to winter conditions. Nobody was held accountable for the neglect of the Confederate troops at Camp Douglas and it's commander was the only Union officer to get a General's rank without seeing active service in the field.

Point Lookout - a Federal prisoner of War Camp for Confederate troops that was vastly overcrowded and overwhelmed. Here Confederate troops suffered mainly because the amount of prisoners held there were too much for the Camp to handle. 50,000 Confederate were held here when it was only designed to hold 10,000 prisoners however only 4,000 prisoners died while at the camp, which is a relatively good percentage compared to other prisoner of War Camps both North and South.

Answer 2

There were over a hundred POW camps both north and south. There was no specific place that held all the prisoners.

Answer 3

Prisoner of war camps were used to: save one sides people by trading for the other prisoners and to keep the other side from having larger amount of troops.
