Organization & Service

The 126th Ohio Infantry (Three Years’ Service) was organized at Camp Steubenville, Ohio, from September 4 to October 11, 1862. Shortly after organization, the regiment was sent to Parkersburg, West Virginia, and remained in western Virginia through the winter and spring of 1862–1863. In June 1863, the regiment was engaged in a skirmish at Martinsburg, where Company I was captured in its entirety.

In October 1863, the regiment participated in the engagement at Bristoe Station and was involved in subsequent skirmishing up to Centerville. The winter of 1863–1864 was spent at Brandy Station. In April 1864, the regiment moved to Rixeyville and prepared for the Overland Campaign under General Grant. The 126th Ohio took part in all major actions from the crossing of the Rapidan River to the crossing of the James River, including heavy fighting at Spotsylvania and Cold Harbor. The regiment was part of Ricketts’ Division, VI Corps, and was actively engaged in assaults and holding captured works.

After crossing the James River, the regiment participated in the initial Petersburg operations and then moved to Baltimore in July 1864. It was transported to Monocacy Junction, Maryland, where it played a significant role in the Battle of Monocacy. The regiment subsequently pursued Confederate forces under General Early, engaging at Snicker’s Gap, Charlestown, and Smithfield. It fought at the Battle of Opequon (Third Winchester), suffering substantial losses, and was also engaged at Fisher’s Hill and Cedar Creek.

In December 1864, the 126th Ohio rejoined the Army of the Potomac and spent the winter in the trenches before Petersburg. On March 25, 1865, the regiment participated in a charge on enemy picket lines, and on April 2, it was in the front line during the final assault on Petersburg. The regiment was mustered out of service on June 25, 1865.
