The Army of the Trans-Mississippi was the major Confederate field army for the Department of the Trans-Mississippi during the American Civil War.[1] It was the last major Confederate command to be surrendered (by General Edmund Kirby Smith on May 26, 1865), the site of the last battle of the war (Palmito Ranch, May 12–13, 1865, a Confederate victory), and the operational theater for many quasi-independent forces, including Quantrill's Raiders, the Missouri Bushwhackers, and Brig. Gen. Stand Watie's Indian regiment (the last remaining Confederate land combatant force, surrendered June 23, 1865).

Overview[edit | edit source]

The Department of the Trans-Mississippi primarily consisted of the four Confederate states west of the Mississippi (Texas, Louisiana, Arkansas, and Missouri), as well as the two Confederate Territories roughly corresponding to the present day states of Oklahoma, New Mexico, and Arizona. Major campaigns fought in this Department included Sibley's New Mexico campaign, Banks's Red River campaign, and Price's Missouri campaign, amongst others.
