Civil War Confederate Brigadier General. Prior to the Civil War, he served as U.S. Agent to the Choctaws in the Oklahoma Indian Territory. In 1855, he successfully negotiated a treaty between the Choctaw and Chickasaw Nations and organized a militia at Fort Washita, Oklahoma. At the outbreak of the Civil War in 1861, he was commissioned a Colonel of the Choctaw and Chickasaw Mounted Rifles. From the fall of 1861 to September 1862, he commanded his Mounted Rifles in engagements against Union forces in Kansas, Arkansas and Missouri. In May 1863, he was promoted Brigadier General and given the command of the Confederate Indian Territory District. Cooper commanded what was known as the "Indian Brigade" in Major General Price's second invasion of Missouri in 1864, which was his last action of the war. After the war, he continued to live in the Oklahoma Indian Territory and was an ardent supporter of Choctaw and Chickasaw land claims against the Federal government.
