Historical Notes:
The 21st Ohio Infantry was organized in response to President Abraham Lincoln's call for volunteers after the outbreak of the Civil War. It was mustered into service on June 6, 1861, at Camp Taylor, near Cleveland, Ohio. The regiment consisted of men primarily from northeastern Ohio.
Initially, the 21st Ohio Infantry served in the Western Theater of the war. It saw action in Kentucky and participated in operations to secure strategic positions in the region.
Campaigning into Tennessee in early 1862 as part of the Army of the Ohio, the regiment was one of a number of Union regiments instrumental in capturing the capital of Nashville in February. From there, the regiment moved toward Murfreesboro, Tennessee, and then to Confederate-held Huntsville, Alabama, in early April.
Concurrent with the move toward Huntsville in April 1862, nine men of the regiment volunteered to participate in a secret mission known as Andrews' Raid. The men, along with two civilians and thirteen soldiers from two other Ohio regiments, dressed in civilian clothes and slipped behind enemy lines. They hijacked the Confederate locomotive The General. The mission was a failure, and all of the raiders were captured. Eight men, including Private John M. Scott of Co. F, 21st Ohio Infantry, were hanged. Another eight, including privates Wilson W. Brown, William J. Knight, John R. Porter, Mark Wood, and John A. Wilson, escaped from captivity. The remaining raiders, among them Private William Bensinger, Private Robert Buffum, and Sergeant Elihu H. Mason of the regiment, were released in a prisoner exchange the next year. In recognition of their actions, Congress awarded most of the raiders, including all nine from the 21st Ohio Infantry the newly created Medal of Honor. Bensinger, Buffum, and Mason were three of the first six men ever to receive the medal.
The Regiment lost during service 6 Officers and 166 Enlisted men killed and mortally wounded and 2 Officers and 218 Enlisted men by disease. Total 392.
