With the diversion in the Shenandoah Valley a complete success, Jackson joined Lee in the Seven Days battles. After the brilliance of the Shenandoah campaign, his service in that week of fighting was disappointing. But he soon redeemed himself. The speedy turning movement executed by his "foot cavalry" against Pope late in Aug., 1862, at the battle of Cedar Mt. set the stage for the crushing victory at the second battle of Bull Run, and in the Antietam campaign he marched promptly to Lee's aid after he had captured the Harpers Ferry garrison.
When Lee reorganized the Army of Northern Virginia after Antietam, he made Jackson commander of the 2d Corps, and Stonewall was promoted to lieutenant general. He ably commanded the Confederate right in the battle of Fredericksburg in December. In the battle of Chancellorsville, Lee and Jackson repeated the tactics of second Bull Run. Jackson's turning movement completely crumbled Hooker's right (May 2, 1863). Pressing on in the darkness, Stonewall Jackson was mortally wounded by the fire of his own men.
His death was a severe blow to the Southern cause. Jackson was a tactician of first rank and, though a strict disciplinarian, had the affection of his men. His devout Calvinism, fighting ability, and arresting personal quirks make him one of the most interesting figures of the war. He was Lee's ablest and most trusted lieutenant.
