Alexander Peter Stewart, "Old Straight" to his men, was born in Rogersville, Tennessee, October 2, 1821. He was graduated from West Point in 1842 and resigned in 1845 to become an educator. From that time until the outbreak of the Civil War he occupied the chair of mathematics and natural and experimental philosophy at Cumberland University, at Lebanon, Tennessee, and at Nashville University. Although a strong antisecessionist Whig in politics, he soon volunteered for the South. The first months of his Confederate service were spent in organizing camps of instruction. After commanding the heavy artillery and water batteries at Belmont, Missouri, he was appointed brigadier general, November 8, 1861, and assigned to a brigade in General Leonidas Polk's command. He fought gallantly in all the battles of the Tennessee Army. He was promoted major general to rank from June 2, 1863, and lieutenant general on June 23, 1864, when he succeeded to the command of Polk's corps. This he led to the end, being finally paroled with General Johnston's army at Greensboro in May 1865. First resuming his professorship at Cumberland University, he later engaged in business in St. Louis from 1870 to 1874. In the latter year he was elected chancellor of the University of Mississippi, a post which he held until his resignation in 1886. General Stewart later was appointed a commissioner of the Chickamauga and Chattanooga National Military Park, serving until his death in Biloxi, Mississippi, August 30, 1908. He is buried in St. Louis.
