the Indian Territory, western Arkansas, southwestern Missouri and southern Kansas. With troops from this district Blunt fought and won the Battle of Honey Springs in 1863, but suffered a defeat at Baxter Springs later that year. Blunt was relieved of command in January 1864. At the same time the District of the Frontier divided up. The Indian Territory and Fort Smith, Arkansas, were designated the District of the Frontier in the Department of Kansas and placed under the command of Colonel William R. Judson. The areas in Arkansas were designated the District of the Frontier in the Department of Arkansas and placed under the command of General John Milton Thayer. Thayer's troops were attached to the VII Corps during the Camden Expedition as the "Frontier Division". On February 23, 1864, Blunt replaced Judson in command of the District of the Frontier, Department of Kansas. Blunt commanded until April 17 when his district was discontinued. Fort Smith was transferred to Thayer's district and the rest of the Indian Territory was divided among other districts. Thayer's District of the Frontier continued until February 1, 1865, when it too was discontinued. Commanders General James G.
