July 5. In August, the regiment returned to Kentucky (Louisville) as the army pursued Confederates under Braxton Bragg, fighting at the Battle of Perryville. The well-travelled regiment then marched to Nashville, Tennessee, in October and November. With the restructuring of the western army in November and the replacement of General Buell with William Rosecrans, the 1st OVI was assigned to the 3rd Brigade, 2nd Division, Right Wing XIV Army Corps, Army of the Cumberland. It stayed in Nashville until December 26, when the regiment departed for a short campaign that culminated in the Battle of Stones River. For much of 1863, the 1st Ohio Infantry was stationed in Tennessee and assigned to the 3rd Brigade, 2nd Division, XX Corps, Army of the Cumberland, until October when the IV Corps was formed from the remnants of the heavily depleted XX Corps and XXI Corps. Under the command of Maj. Joab A. Stafford, the regiment saw action at the Battle of Chickamauga, a stinging defeat for Rosecrans' army. It marched to Knoxville as part of the army relieving the Confederate siege of Union forces at that city. Yet another reorganization of the army resulted in the 1st Ohio Infantry being assigned to the 2nd Brigade, 3rd Division, 4th Army Corps, Army of the Cumberland, until September 1864. It fought under Grant at Missionary Ridge, where it was the first regiment to plant its colors on the hilltop, and with Sherman in the Atlanta campaign. The regiment spent much of the rest of the fall on scouting duty in Tennessee. The 1st Ohio Volunteer Infantry mustered out of the Union army from September 24 to October 14, 1864, when the 3-year term of enlistment expired. A number of recruits re-enlisted and transferred to the 18th Ohio Volunteer Infantry on October 31, 1864, and remained on duty through the end of the Civil War. The regiment lost during its service 5 officers and 116 enlisted men killed and mortally wounded in combat and 130 enlisted men by disease (a total of 251 fatalities). It was engaged in 24 battles and skirmishes, lost 527 men in action, and marched 2,500 miles. Following the war, the veterans erected a monument on the Shiloh National Military Park. The regiment is also commemorated on the Soldiers' and Sailors' Monument in Public Square in downtown Cleveland. The tattered battle flags of both the three-months and three-years regiments (as well
