The Arkansas infantry regiments assigned to General E. Kirby Smith's Department of the Trans-Mississippi were surrendered on May 26, 1865. When the Trans-Mississippi Department surrendered, all of the Arkansas infantry regiments were encamped in and around Marshall, Texas, as war-ravaged Arkansas was no longer able to provide adequate sustenance to the army. The regiments were ordered to report to Shreveport, Louisiana, to be paroled. None of them did so. Some soldiers went to Shreveport on their own to be paroled, but the regiments simply disbanded without formally surrendering. Most of the Arkansas Cavalry units were surrendered by Brigadier General M. Jeff Thompson, Commander of the Military Sub-District of Northeast Arkansas and Southeast Missouri. General Thompson agreed to surrender his command at Chalk Bluff on May 11, 1865, and agreed to have his men assemble at Wittsburg and Jacksonport to lay down their arms and receive their paroles. The cavalry units formally surrendered and were paroled at Wittsburg on May 25, 1865 or at Jacksonport on June 5, 1865. Many smaller commands surrendered at various Union posts, including Fort Smith, Pine Bluff and Little Rock in May and June 1865.
