The regiment served primarily in the Eastern and Western Theaters, participating in major campaigns and battles with the Army of the Potomac and later the Army of the Cumberland. It was known for its involvement in significant engagements such as Chancellorsville, Gettysburg, and the Atlanta Campaign.

Organization & Service
The 55th Ohio Infantry (Three Years’ Service) was organized at Norwalk, Ohio, from September to December 1861. The regiment mustered in under Colonel John C. Lee. In January 1862, it moved to Grafton, West Virginia, and shortly thereafter to New Creek. The regiment was attached to various brigades and divisions, initially serving in the Department of West Virginia and later in the Army of the Potomac and the Army of the Cumberland.
At the battle of McDowell in May 1862, the 55th Ohio served as reserve and supported an artillery battery, though the battery was not brought into action due to terrain. The regiment was present but not engaged at Cross Keys. During the Second Battle of Bull Run, it was under heavy artillery fire but did not engage the enemy’s main line. The winter of 1862–1863 was spent at Brooks’ Station, Virginia, with duties including inspections, drills, and picket service.
In May 1863, the regiment fought at Chancellorsville, suffering significant losses. It marched with the Army of the Potomac into Pennsylvania and was present at Gettysburg, where it lost about 50 men. After Gettysburg, the 55th Ohio was transferred to Tennessee and participated in the Battle of Missionary Ridge, helping to drive Confederate forces beyond the East Tennessee Railroad.
In January 1864, 319 men reenlisted as veterans and were furloughed home, but returned in time for the Atlanta Campaign. The regiment participated in all major actions of the 20th Corps during this campaign, including the battles of Resaca, Cassville, Kennesaw Mountain, and the siege of Atlanta. The 55th Ohio left Lookout Valley with approximately 400 men and lost over 200 during the campaign. It continued with Sherman’s March to the Sea and the Carolinas Campaign, fighting at Averasboro and Bentonville. The regiment was mustered out on July 11, 1865.
