23rd Ohio Infantry Regiment

23rd Ohio Infantry Regiment was a prominent volunteer infantry formation of the Union Army during the American Civil War. Organized in the early summer of 1861 at Camp Chase in Columbus, Ohio, the regiment served with distinction in the Eastern Theater and later in the Shenandoah Valley. It is historically renowned for its roster of future political and military leaders, including a U.S. President and a Supreme Court Justice, who began their careers within its ranks.

Formation and early service

The 23rd Ohio was mustered into federal service on June 11, 1861, for a three-year term under the command of Colonel William S. Rosecrans. Its initial organization occurred at the state military camp, Camp Chase, with companies drawn from numerous counties across central and southern Ohio. The regiment's first significant assignment was to the mountainous region of western Virginia, present-day West Virginia, where it participated in early campaigns to secure the area for the Union. Under the overall command of Major General George B. McClellan in the Department of the Ohio, the unit engaged in operations against Confederate forces and guerrilla bands, helping to establish Federal control in the Kanawha Valley.

Civil War engagements

The 23rd Ohio saw extensive combat throughout the war. In 1862, it fought at the Battle of South Mountain and the pivotal Battle of Antietam as part of the IX Corps, suffering significant casualties in the latter engagement at Burnside's Bridge. The regiment was subsequently transferred to the Department of West Virginia and endured hard campaigning in the Shenandoah Valley. It participated in the Battle of Cloyd's Mountain in 1864 and played a crucial role in Major General Philip Sheridan's Valley Campaigns of 1864, including the decisive victories at the Battle of Opequon (Third Winchester) and the Battle of Cedar Creek. Its service concluded with participation in the final campaigns around Petersburg and the subsequent pursuit of General Robert E. Lee's Army of Northern Virginia to Appomattox Court House.

Commanders and notable members

The regiment's leadership was exceptionally distinguished. Its first colonel, William S. Rosecrans, later became a prominent Union major general commanding the Army of the Cumberland. He was succeeded by Colonel Eliakim P. Scammon. Future President of the United States Rutherford B. Hayes served as a major and later lieutenant colonel, commanding the regiment after being wounded at the Battle of South Mountain. Future Associate Justice of the Supreme Court of the United States, William McKinley, enlisted as a private and was commissioned a second lieutenant for bravery at the Battle of Antietam. Other notable officers included Lieutenant Colonel James M. Comly, who later became a journalist and diplomat, and Major John G. Mitchell.

Casualties and legacy

During its four years of service, the 23rd Ohio sustained heavy losses, reflecting its front-line role in numerous major battles. The regiment's total casualty count exceeded 300 men killed or mortally wounded, with many more lost to disease, a common scourge in Civil War camps. Its legacy is cemented not only by its combat record but also by its remarkable role as a proving ground for national leadership. The unit is famously known as the only Civil War regiment to produce two future U.S. Presidents, Rutherford B. Hayes and William McKinley, a unique distinction in American military history. Its battle honors are commemorated on the Antietam National Battlefield and other historic sites.

Postwar activities

The 23rd Ohio Infantry was mustered out of service on July 26, 1865, at Camp Chase, the same location where it was organized. Veterans of the regiment played active roles in postwar society, politics, and the influential veterans' organization, the Grand Army of the Republic. The association of Hayes and McKinley provided a powerful political network for Ohio Republicans in the late 19th century. The regiment's history and memory were preserved through unit reunions, published memoirs, and the personal papers of its famous members, which are held in archives such as the Rutherford B. Hayes Presidential Center in Fremont, Ohio.
