Trans-Mississippi Department


The Trans-Mississippi Department was a former geographical subdivision of the Confederate States Army comprising the states of Missouri, Arkansas, Louisiana, Texas, the Arizona Territory and the Indian Territory. It was the last military department to surrender to United States forces in 1865.

History

The Trans-Mississippi Department was established on May 26, 1862, at Little Rock, Arkansas. It absorbed the previously established Trans-Mississippi District which had been organized on January 10, 1862, to include the Indian Territory, Missouri, Arkansas, Missouri, and that part of Louisiana north of the Red river. The Trans-Mississippi Department had its headquarters at Shreveport, Louisiana, and Marshall, Texas. It was responsible for the Confederate theater of operations west of the Mississippi. Its forces were sometimes referred to as "Army of the Southwest" and, as a result of being largely cut off from the Confederate government in Richmond late in the War, became popularly known as "Kirby-Smithdom."
