Camp Chase was a military staging, training and prison camp in Columbus, Ohio, during the American Civil War. All that remains of the camp today is a Confederate cemetery containing 2,260 graves. It was a Civil War camp established in May 1861, on land leased by the U.S. Government. It served as a replacement for the much smaller Camp Jackson. Four miles west of Columbus, the main entrance was on the National Road. Boundaries of the camp were present-day Broad Street (north), Hague Avenue (east), Sullivant Avenue (south), and near Westgate Avenue (west). Named for former Ohio Governor and Lincoln's Secretary of the Treasury Salmon P. Chase, it was a training camp for Ohio volunteer army soldiers, a parole camp, a muster-out post, and a prisoner-of-war camp. The nearby Camp Thomas served as a similar base for the Regular Army.
