Sherman, who was repulsed at Chickisaw Bluffs on December 29. Although Grant was humiliated by devastating raids of both Van Dorn and Forrest, he was not fired, owing to Grant's previous victories at Fort Henry, Fort Donelson, Shiloh, Iuka, and Corinth. President Lincoln revoked Grant's controversial General Order No. 11. Although Grant was thwarted in his first attempt to capture Vicksburg, saved by Van Dorn, Grant's second attempt was successful, capturing Vicksburg on July 4, 1863. Grant never forgot the sting of the Confederate cavalry, inflicted by Van Dorn and Forrest, and he later incorporated the Union Cavalry as a separate fighting unit, under Union General Phil Sheridan, during the Overland Campaign, in 1865. Appointed cavalry commander On January 13, 1863, Van Dorn was appointed to command all cavalry in the Department of Mississippi & East Louisiana, and then was ordered by Gen. Joseph E. Johnston to join the Army of Tennessee, operating in Middle Tennessee. Van Dorn and his force left Tupelo, Mississippi, went through Florence, and reached the army on February 20 at Columbia, Tennessee. Van Dorn set up his headquarters at Spring Hill at White Hall and assumed command of all of the surrounding cavalry from there. He was ordered by the army commander, Gen. Braxton Bragg, to protect and scout the left of the army, screening against Union cavalry. Battle of Thompson's Station Van Dorn was also successful at Battle of Thompson's Station, on March 5, 1863. There a Union brigade, under Col. John Coburn, left Franklin to reconnoiter to the south. About four miles short of Spring Hill Coburn attacked a Confederate force composed of two regiments and was repulsed. Van Dorn then sent Brig. Gen. William Hicks Jackson's dismounted soldiers to make a direct frontal assault, while Brig. Gen. Bedford Forrest's troopers went around Coburn's left and into the Federal rear. After three charges were beaten back, Jackson finally carried the Union position as Forrest captured Coburn's wagon train, blocking the road to Columbia and the only Union escape route. Nearly out of ammunition as well as surrounded, Coburn surrendered. First Battle of Franklin On March 16, 1863, Van Dorn was given command of the cavalry corps of the Army of Tennessee and fought his last fight April 10 at the First Battle of Franklin, skirmishing with the cavalry of Gordon Granger and losing 137 men to Granger's 100 or so.
