Douglas Hancock Cooper
Douglas Hancock Cooper, a native of Mississippi, was born November 1, 1815, probably in Amite County, where his father, a physician and Baptist preacher, was discharging his ecclesiastical duties at the time. After attending the University of Virginia from 1832 to 1834, the son returned to Mississippi and engaged in planting in Wilkinson County. During the Mexican War he served as captain of the 1st Mississippi Rifles, and in 1853 was appointed by President Franklin Pierce U. S. agent to the Choctaw Nation in Indian Territory. In 1861 he was deputed by the Confederate government to secure the allegiance of the Indians, and was commissioned colonel of the 1st Choctaw and Chickasaw Mounted Rifles. He commanded the Indians at Elkhorn and at Newtonia, Missouri, and was subsequently promoted brigadier general to rank from May 2, 1863. His last important military service was rendered as commander of the Indian brigade in General Sterling Price's second invasion of Missouri. After the war General Cooper prosecuted the claims of the Choctaws and Chickasaws against the Federal government, claims arising out of nonperformance by the government in connection with the removal of the tribes from their original lands. He died at Old Fort Washita in the Chickasaw Nation (in what is now Bryan County, Oklahoma) April 29, 1879, and is buried in the Fort cemetery in an unmarked grave.
