Overview
The 151st Ohio Infantry (One Hundred and Fifty-first Ohio National Guard Infantry, 100 Days’ Service) was an infantry regiment from Ohio that served in the Union Army during the American Civil War. Organized at Camp Chase in Columbus, Ohio, the regiment mustered into federal service on May 13, 1864, for a term of 100 days. It was composed primarily of men from the 33rd Regiment, Ohio National Guard (Allen County), and the 57th Battalion, Ohio National Guard (Hocking County). The regiment was assigned to the defenses of Washington, D.C., during a critical period in the summer of 1864.
Organization & Service
The 151st Ohio Infantry was organized at Camp Chase and mustered into service on May 13, 1864. The following day, the regiment departed for Washington, D.C., traveling via the Ohio Central and Baltimore railroads. Upon arrival in Washington on May 21, the regiment reported to General Christopher C. Augur and was assigned to garrison duty at several forts protecting the capital, including Forts Sumner, Mansfield, and Simmons.
During the Confederate advance on Washington in July 1864, elements of the regiment were actively engaged in the defense of the city. Companies C and G were stationed at Fort Stevens, Company I at Battery Smead, and Company K at Fort Kearny, all of which came under fire during the Battle of Fort Stevens. On August 17, the regiment received orders to concentrate at Fort Simmons. Shortly thereafter, it was ordered to return to Ohio, traveling via Baltimore and Pittsburgh to Camp Chase, where it arrived on August 23. The regiment was mustered out of service on August 27, 1864.
