The Pierce County Jail was a temporary prisoner of war camp located in Blackshear, Georgia, during the American Civil War.During Union Maj. Gen. William T. Sherman's 1864 "March to the Sea," Confederate officials hastily made plans to evacuate a number of existing POW camps and relocate their occupants farther from the Federal army. As Blackshear is deep in southeast Georgia in a pine forest, it was thought to be a safe place for this relocation.
