On March 13, 1862, the Valley District was incorporated into the
Army of Northern Virginia, under General
Joseph E. Johnston. Jackson and the Stonewall Brigade operated in the Valley as part of the left wing of Johnston's army. During Jackson's
Valley Campaign, Jackson's only defeat of the Civil War occurred at the
First Battle of Kernstown on March 25, 1862. After receiving faulty intelligence, the brigade was ordered to attack a much larger Union force. Out of ammunition and almost surrounded by the superior force, Garnett ordered a withdrawal. Jackson was infuriated by this action, taken without his explicit permission, and Garnett was relieved of command and subject to court martial (Garnett was later killed during
Pickett's Charge in the
Battle of Gettysburg, attempting to restore his military honor). For the remainder of the Valley Campaign, Brig. Gen.
Charles S. Winder commanded the brigade and there were no more defeats in store. The brigade marched over 400 miles in four weeks, was victorious in six significant battles, and helped Jackson achieve a strategic victory in the Eastern Theater. The brigade's mobility in the campaign (particularly a 57-mile march in 51 hours) earned it the
oxymoronic title "Jackson's foot cavalry". At the end of the Valley Campaign, the brigade moved to reinforce General
Robert E. Lee in the
Seven Days Battles on the
Virginia Peninsula. In the
Battle of Gaines' Mill, the brigade assaulted the Federal right and helped Lee achieve a victory. In the
Northern Virginia Campaign, the brigade suffered high casualties at the
Battle of Cedar Mountain and General Winder was killed on August 9, 1862. Jackson personally rallied his old brigade and won the battle. The brigade would suffer more casualties in the
Second Battle of Bull Run. On August 30, 1862, the Stonewall Brigade repulsed the attack of the Union's
Iron Brigade and rallied for a counterattack. Its acting commander, Colonel
William S. Baylor, was killed. Colonel
Andrew J. Grigsby assumed command and led the brigade through the
Maryland Campaign and the
Battle of Antietam. The brigade defended the West Woods, where the fighting was so severe and attrition so high that Grigsby was commanding the division ("Jackson's Division") by the end of the day. Grigsby did not receive permanent command of the brigade, for reasons Jackson did not record. Instead, Brig. Gen.
Elisha F. Paxton, former commander of the
27th Virginia Infantry, moved from Jackson's staff to brigade command, which he performed in the
Battle of Fredericksburg. There, under the division command of
William B. Taliaferro, the brigade was on the right flank of the Confederate defense and counterattacked the encroaching Union division of
George G. Meade, but was overall lightly engaged. In 1862, casualties in the brigade surpassed 1,200. ==1863==
