other times the "Right Wing" of the army. In the fall, during the invasion of Kentucky by Bragg and Maj. Gen. Edmund Kirby Smith, Polk was in temporary command of the Army of Mississippi while Bragg visited Frankfort to preside over the inauguration of a Confederate governor for the state. Polk disregarded an order from Bragg to attack the flank of the pursuing Union Army near Frankfort. At the Battle of Perryville, Polk's right wing constituted the main attacking force against Maj. Gen. Don Carlos Buell's Army of the Ohio, but Polk was reluctant to attack the small portion of Buell's army that faced him until Bragg arrived at the battlefield. One enduring legend of the Civil War is that when Polk observed his subordinate, Maj. Gen. Benjamin F. Cheatham, advancing his division, and Cheatham allegedly shouted, "Give 'em hell, boys!", Polk seconded the cheer while retaining the sensibility of a clergyman: "Give it to 'em, boys; give 'em what General Cheatham says!" Army of Tennessee After Perryville, Polk began a year-long campaign to get Bragg relieved of command, hoping to use his close relationship with President Davis to accomplish his goal. Despite the failure of his Kentucky campaign, Bragg was retained in command, but this did nothing to reduce the enmity between Polk and Bragg. Polk was promoted to lieutenant general on October 11, 1862, with date of rank of October 10. He became the second most senior Confederate of that rank during the war, behind James Longstreet. In November, the Army of Mississippi was renamed the Army of Tennessee and Polk commanded its First Corps until September 1863. Polk fought under Bragg at the Battle of Stones River in late 1862 and once again Bragg's subordinates politicked to remove their army commander after an unsuccessful battle (the battle was tactically inconclusive, but Bragg was unable to stop the advance of the Union Army of the Cumberland under Maj. Gen. William S. Rosecrans and Bragg withdrew his army to Tullahoma, Tennessee). Bragg was also unsuccessful in resisting Rosecrans's advance in the Tullahoma Campaign, which began to threaten the important city of Chattanooga. In the face of Rosecrans's expert maneuvering of his army, Polk counseled Bragg to retreat rather than stand and fight in their Tullahoma fortifications. Rosecrans eventually maneuvered Bragg out of Chattanooga and the Army of Tennessee withdrew into the mountains of northwestern Georgia with the Army of
