Overview
The 160th Ohio Infantry (One Hundred Days’ Service) was an infantry regiment from Ohio that served in the Union Army during the American Civil War. Organized at Zanesville, Ohio, between May 12 and May 14, 1864, the regiment was composed primarily of Ohio National Guard battalions from Perry, Muskingum, Brown, and Fairfield counties. The unit was mustered in for a term of 100 days and served in the Eastern Theater, primarily in the Shenandoah Valley and surrounding areas.
The 160th Ohio Infantry was part of the Union’s effort to provide short-term troops for rear-area and garrison duties, thereby freeing veteran regiments for front-line service during the critical summer campaigns of 1864.
Organization & Service
The 160th Ohio Infantry (One Hundred Days’ Service) was organized at Zanesville, Ohio, from May 12 to May 14, 1864. The regiment was formed from the 53rd Battalion (Perry County), 91st Battalion (Muskingum County), part of the 40th Battalion (Brown County), and part of the 73rd Battalion (Fairfield County) of the Ohio National Guard. Upon organization, the regiment was immediately sent to Harper’s Ferry, West Virginia, where its initial duty involved guarding a supply train to Martinsburg.
After returning from Martinsburg, the regiment was assigned to the 1st Brigade, 1st Division of General Hunter’s army. On May 25, 1864, it moved with the division to Woodstock, Virginia. The regiment marched with Hunter’s forces toward the front but was soon detached to escort another supply train back to Martinsburg. Near Middletown, the regiment was engaged in a skirmish with Mosby’s guerrillas. For the remainder of its service, the 160th Ohio Infantry was frequently on the move throughout the Shenandoah Valley, participating in several skirmishes and performing guard and escort duties. The regiment departed for Ohio on August 25, arrived in Zanesville on August 29, and was mustered out of service on September 7, 1864, upon the expiration of its term.
