Today the nominated area of about 1.4 acres is a Confederate cemetery with a memorial arch.","why_significant":"Camp Chase began as a Union training camp in 1861 and became a military prison. It held 26,000 of the 36,000 Confederate prisoners of war in Ohio military prisons, and 2,260 soldiers died there by the time it closed in July 1865. The site is significant for its military and political associations with the Civil War.","narrative":"Camp Chase occupied flat farmland leased to the federal government at the start of the Civil War, on what is now Sullivant Avenue in Columbus. Dedicated on June 20, 1861, and named for Salmon P. Chase, it first trained Union recruits before becoming a military prison. Confederate prisoners were held in a series of stockades and barracks, and by 1864 new barracks raised capacity to 8,000 men. The camp held 26,000 of the 36,000 Confederate prisoners in Ohio's military prisons. Overcrowding, reduced rations, disease and the cold winter of 1865 led to 2,260 deaths before the camp closed on July 5, 1865. No original buildings remain. A cemetery established in 1863 now covers less than two acres, with a stone wall built in 1921, marble headstones for 2,199 Confederate soldiers, a granite memorial arch unveiled in 1902 topped by a bronze soldier, and a stone speaker's platform.","period_of_significance":"1861-1865","architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"None of the original camp structures survive; all were dismantled at the end of the Civil War.
