Prisoners at Andersonville - stock illustration

Andersonville, or Camp Sumter as it was known officially, held more prisoners at any given time than any of the other Confederate military prisons. It was built in early 1864 after Confederate officials decided to move the large number of Federal prisoners in and around Richmond to a place of greater security and more abundant food. During the 14 months it existed, more than 45,000 Union soldiers were confined here. Of these, almost 13,000 died from disease, poor sanitation, malnutrition, overcrowding, or exposure to the elements.
