91st Ohio Infantry

The 91st Ohio Volunteer Infantry Regiment was an infantry regiment that served in the Union Army during the American Civil War. It primarily served in West Virginia and in the Shenandoah Valley region of Virginia.

Service
The 91st Ohio was raised at Camp Ironton in south-central Ohio on August 26, 1862. After being organized and mustered into Federal service in September, the regiment was transported to western Virginia and assigned to the Department of the Kanawha and later to the VIII Corps under Brig. Gen. Eliakim Scammon. It participated in a series of raids and operations against Confederate positions in the region.

In the spring of 1864, the 91st OVI fought in the Battle of Cloyd's Mountain in Pulaski County, Virginia, during Maj. Gen. George Crook's expedition to disrupt the Virginia & Tennessee Railroad, an important Confederate supply line. Later, it fought in the Battle of Piedmont and then participated in the Valley Campaigns of 1864, including the battles of Berryville, Opequon or Third Winchester, Fisher's Hill, and Cedar Creek.

For the rest of the war, the regiment split its time between garrisons in Cumberland, Maryland, and Winchester, Virginia. The 91st Ohio was mustered out at Cumblerland on June 24, 1865, and subsequently transported by train back to Ohio.

During its time of service, the 91st lost 3 Officers and 60 enlisted men killed and mortally wounded during battle, and 3 Officers and 87 enlisted men perished from disease, for a total loss of 153 soldiers.
