Organized at Camp Wood, Cleveland, Ohio, between August 26 and October 29, 1861, the regiment was mustered in for a three-year term. It participated in numerous major campaigns and battles in the Western Theater, earning distinction for its conduct and heavy losses in several engagements.
Upon the expiration of its original term, non-veteran members were mustered out, while veterans and recruits continued to serve until the regiment was finally mustered out on November 27, 1865. The 41st Ohio Infantry is noted for its high casualty rates in key battles and for commendations received from commanding generals for its performance under fire.
Organization & Service
The 41st Ohio Infantry (Three Years’ Service) was organized at Camp Wood, Cleveland, Ohio, from August 26 to October 29, 1861. The regiment was mustered into Federal service for three years and assigned to the Army of the Ohio, later serving in the Army of the Cumberland. Throughout its service, the regiment was attached to various brigades and divisions, participating in major campaigns across Tennessee, Georgia, and Alabama.
The regiment saw its first major action at the Battle of Shiloh in April 1862, where it suffered significant casualties. It continued to serve in the Western Theater, fighting at Stone’s River, Liberty Gap, Chickamauga, Brown’s Ferry, Chattanooga, Orchard Knob, and Missionary Ridge. The 41st participated in the Atlanta Campaign, including actions at Rocky Face Ridge, Resaca, Dallas, Kennesaw Mountain, and the Siege of Atlanta. It later fought at Franklin and Nashville. After the original three-year term expired, non-veterans were mustered out, but the regiment, composed of veterans and recruits, remained in service until November 27, 1865, when it was mustered out by order of the War Department.
