Overview

The Kanawha Division was a Union Army formation whose organizational history began with a brigade of Ohio volunteer regiments commanded by Brigadier General Jacob D. Cox in 1861. Cox named the brigade for the Kanawha Valley in western Virginia, where Union forces were operating during the opening phase of the American Civil War. Although the formation changed size, designation, command structure, and higher headquarters several times, the Kanawha name remained associated with a succession of Union troops active in the mountain regions of Virginia and in major campaigns in the Shenandoah Valley. The formation first operated as the Kanawha Brigade and became part of the District of the Kanawha, also commanded by Cox. Elements fought at Kanawha Gap in September 1861, and the brigade participated in the 1862 fighting around Princeton Court House. By the middle of 1862, the organization had expanded to division strength, and the designation Kanawha Division was being used officially in the Mountain Department. In the period leading to the Second Battle of Bull Run, Cox and the division were transferred to the Army of Virginia. Only one brigade, commanded by Colonel Eliakim P. Scammon, took part in the preliminary fighting near Bull Run Bridge on August 27, 1862. After the Union defeat, the division was assigned to the Washington defenses. The division returned to field operations during the Maryland Campaign and was attached to the IX Corps. It fought at South Mountain under Cox and then participated in the Battle of Antietam. Command arrangements were unusually fluid because the death of IX Corps commander Jesse L. Reno at South Mountain led Cox to assume corps command, while Scammon took over the division. The division's brigades were subsequently led by Hugh Ewing and George Crook. At Antietam, Crook's brigade supported the fighting near Burnside Bridge, while Ewing's brigade crossed Antietam Creek at Snavely's Ford. After Antietam, the formation returned to western Virginia. It was increasingly involved in irregular operations and counter-guerrilla activity rather than large conventional battles. During this phase it lost the formal Kanawha Division designation and was identified as the 3rd Division in the Department of West Virginia. Carr B. White organized Blazer's Scouts from troops associated with the division to conduct mobile operations against Confederate partisan forces. George Crook commanded the formation for a period, followed by Scammon, before Crook returned to command in February 1864. In 1864 the formation was officially the 2nd Division in the Department of West Virginia. It contained three brigades led by Rutherford B. Hayes, Carr B. White, and Horatio G. Sickel, with Ohio, West Virginia, and Pennsylvania regiments. Crook led the division at Cloyd's Mountain and during David Hunter's campaign toward Lynchburg. In July, Crook organized a larger field force known as the Army of the Kanawha and temporarily commanded two Kanawha divisions. That force was renamed the Army of West Virginia in August and joined Philip Sheridan's operations in the Shenandoah Valley under the VIII Corps. The division fought at the battles of Opequon, Fisher's Hill, and Cedar Creek. At Opequon, the division was initially held in reserve before being committed at a decisive point; Hayes's brigade made a flank attack, while division commander Isaac H. Duval was wounded and Hayes assumed command during the battle. Crook retained Hayes as division commander afterward, and Hayes helped coordinate the successful Union attack at Fisher's Hill. At Cedar Creek, the division bore the brunt of the Confederate surprise attack, and Hayes was wounded. The engagement was the formation's last major battle. Hayes remained in command until December 1864. The Kanawha Division was therefore less a continuously stable administrative unit than a lineage of related Union formations whose commanders and designations changed as the war progressed.

History

The Kanawha Division originated on July 1, 1861, when Brigadier General Jacob D. Cox assumed command of a brigade composed of Ohio volunteer regiments. Cox named the organization the Kanawha Brigade because it was assigned to the Kanawha Valley in western Virginia. A portion of the 34th Ohio Infantry fought at Kanawha Gap in September 1861. The brigade became part of the District of the Kanawha, which Cox also commanded, and took part in the 1862 operation at Princeton Court House. By 1862, the formation had expanded to division size. The Kanawha Division designation was in official use by June while the unit served in the Mountain Department. Cox and the division were transferred to the Army of Virginia in preparation for the Second Battle of Bull Run. Only Scammon's brigade was engaged, in preliminary fighting near Bull Run Bridge on August 27. After the campaign, the division was moved to the Washington defenses. During the Maryland Campaign, the Kanawha Division was attached to the IX Corps. Cox led it at South Mountain, but the death of IX Corps commander Jesse L. Reno created a succession problem. Cox assumed corps command, while Colonel Eliakim P. Scammon took command of the division. At Antietam, the division operated with brigades led by Hugh Ewing and George Crook. Crook's troops crossed in support of the fighting near Burnside Bridge, and Ewing's brigade crossed Antietam Creek at Snavely's Ford. Following Antietam, the division returned to western Virginia. George Crook commanded it during part of the winter of 1862–1863, after which he was transferred and Scammon resumed command. The unit was then formally identified as the 3rd Division in the Department of West Virginia rather than the Kanawha Division. Its operations became more focused on guerrilla warfare and counter-partisan activity, including actions against forces associated with John S. Mosby. Colonel Carr B. White organized Blazer's Scouts from troops connected with the division. Rutherford B. Hayes, one of the brigade commanders, criticized the cautious pace under Scammon and favored Crook's more aggressive leadership. Crook returned to command in February 1864. The formation was then the 2nd Division in the Department of West Virginia and contained three brigades commanded by Rutherford B. Hayes, Carr B. White, and Horatio G. Sickel. Its regiments included troops from Ohio and West Virginia, as well as two Pennsylvania regiments. Crook led the division at Cloyd's Mountain before it joined David Hunter's army in the movement toward Lynchburg. On July 2, 1864, Crook organized a larger force called the Army of the Kanawha and personally commanded its first and second Kanawha divisions for a short period. By late July, Joseph Thoburn and Isaac H. Duval had taken command of those divisions. The force was renamed the Army of West Virginia on August 8 and joined Philip H. Sheridan's army near Winchester as part of the VIII Corps. At Opequon, Duval's division was initially held in reserve but was committed when the battle reached a critical stage. Hayes's brigade made a flank attack, and Duval was wounded. Hayes then assumed command of the division. Crook retained Hayes despite interest from several brigadier generals. At Fisher's Hill, Hayes and Crook helped coordinate a successful flank operation. At Cedar Creek, the Confederate surprise attack initially overwhelmed Crook's command, Hayes was wounded, and the division suffered heavily. Cedar Creek was its last major battle, and Hayes remained in command until December 1864. The formation's changing names and structures reflect Civil War reorganizations rather than a single uninterrupted divisional establishment.
