The only battlefield of significance in Ohio is Buffington Island. Today it is threatened by development. This was the site of the largest fight of the July 1863 dash across Ohio by Confederate cavalry under John Hunt Morgan. The incursion was immortalized as "Morgan's Raid". A lesser engagement was the Battle of Salineville, which resulted in the capture of General Morgan. He and a number of his officers were incarcerated in the Ohio Penitentiary before escaping. Extreme south-central Ohio had previously been briefly invaded in early September 1862 by cavalry under Albert G. Jenkins.
