The 46th Ohio Infantry Regiment was an infantry regiment in the Union Army during the American Civil War. The 46th was armed rather differently from most infantry regiments in the Civil War. In March 1864 many of the regiment's men re-enlisted as the 46th Ohio Veteran Infantry Regiment and received a 30-day furlough. Upon return to its encampment at Scottsboro, Alabama, in April 1864, the regiment exchanged its muzzleloading rifle-muskets for the Spencer repeating rifle. The colonel of the 46th Ohio, Charles C. Walcutt, wrote a manual of arms for the Spencer, and the regiment first employed its Spencers in force at the Battle of Resaca.
The 46th Ohio Infantry Regiment was organized in Worthington, Ohio October 16, 1861, through January 28, 1862, and mustered in for three years service under the command of Colonel Thomas Worthington.
