During the Civil War over 150 prison camps were established throughout the North and South. Between 350,000 and 400,000 men from both sides were held as prisoners-of-war of whom roughly 56,000 died. Historians have suggested that incompetence was the main cause. For both the Union and Confederacy, the care and feeding of prisoners were last on the list of priorities. The Union could have done a better job but did not, while the Confederacy had trouble even providing for their own soldiers. About twenty prison camps earned bad reputations. For Union soldiers the worst was Andersonville in Georgia while for Confederate soldiers it was Elmira.
