This regiment was organized at Camp Dennison, from June 19 to 29, 1861, to serve for three years. It left for the Kanawha valley on July 6, arrived at Point Pleasant on the 9th, and on the 17th fought the battle of Scary creek, W. Va., the enemy being strongly posted beyond a ravine. The regiment fought for 3 hours and after exhausting its ammunition fell back in good order to its camp at the mouth of the Pocotaligo, with a loss of 5 killed, 30 wounded and 4 missing. The regiment entered Charleston, W. Va., and a few days later reached Gauley bridge, where it captured a large quantity of arms and ammunition. Marching south through Weston, Sutton and Summerville it arrived at Carnifix ferry on Sept. 10, and engaged in the battle at that place with a loss of 2 killed and 10 wounded. The regiment was ordered to the Army of the Potomac on Aug. 15, 1862; met the enemy at Bull Run bridge on the 27th, where it was severely engaged for 6 hours against a greatly superior force and was compelled to fall back to Fairfax Station with a loss of 9 killed, 68 wounded (six mortally) and 12 missing. On Sept. 7 it advanced into Maryland, and after a sharp skirmish at Monocacy bridge entered Frederick City. It engaged in the battle of South mountain, participating in three bayonet charges and capturing 3 battle-flags, a large number of small arms, and over 200 prisoners, with a loss of 16 killed, 91 wounded, and 8 missing. Three days later it was engaged at Antietam, losing 6 killed and 29 wounded. After wintering in West Virginia, it assisted in the repulse of the enemy's attack on Fayette Court House, the regiment losing 2 killed, 9 wounded and 8 missing. The regiment was next engaged at Cloyd's mountain, where it lost 11 killed, 68 wounded and in addition to these 20 men, left on the field in charge of the wounded, fell into the enemy's hands. It also participated in an engagement at Lynchburg, Va., and then was ordered to Columbus, Ohio, where it was mustered out on July 11, 1864.Footnotes:
