# Department of Kansas

The Department of Kansas was a Union Army command department in the Trans-Mississippi Theater during the American Civil War. This department existed in three different forms during the war.

## 1861

The first "Department of Kansas" was created on November 9, 1861 from the Western Department. It included Kansas, Nebraska Territory, Colorado Territory, Dakota Territory and the Indian Territory (present day Oklahoma). On March 11, 1862 the department was absorbed into the Department of the Mississippi. Brigadier General David Hunter was the sole commander during this period. During this interlude a District of Kansas existed under the command of Brigadier General James W. Denver from March 19-April 10, 1862.

## 1862

Two months later the Department of Kansas was reformed out of the Dept. of Mississippi on May 2, 1862. This form of the department included all previous territories except Fort Garland, Colorado. Brigadier General James G. Blunt was appointed commander. On August 16, Blunt created the Army of Kansas which was virtually synonymous with the department. Nebraska and Dakota Territories were detached and transferred to the Department of the Northwest and shortly after on October 11 the Department of Kansas was absorbed into the Department of the Missouri.

## 1864

On January 1, 1864 the third formation of the Department of Kansas was created. It included Kansas, Nebraska Territory, Colorado Territory (except Fort Garland), Indian Territory, and Fort Smith, Arkansas. Major General Samuel R. Curtis was appointed command. Fort Smith and the Indian Territory were transferred to the Department of Arkansas in April. On October 13 Curtis organized the Army of the Border, composed of troops from his department to confront Price's Missouri Raid. For the first time of the war troops from the Department of Kansas were involved in a major campaign, turning back Price's Confederates at the Battle of Westport. The Army of the Border was disbanded on November 9. It was also during this time that Colonel John M. Chivington, commander of the District of Colorado Territory, committed the Sand Creek massacre against the Cheyenne and Arapaho people on November 29, 1864. Shortly after Department of Kansas was merged into the Dept. of Missouri once again.
