Army of the Shenandoah (Confederate)
The Army of the Shenandoah began as scattered militia companies sent to Harpers Ferry, Virginia. Robert E. Lee appointed Thomas J. Jackson to organize these groups in early 1861. Jackson formed five infantry regiments and an artillery battery from the available volunteers. This collection became the foundation for what would later be known as the Stonewall Brigade. Joseph E. Johnston took command on May 15 after replacing Jackson at the post. He expanded the force to include four brigades of infantry and a cavalry regiment led by J. E. B. Stuart.
Union forces under Robert Patterson moved south toward Harpers Ferry in mid-June 1861. Johnston feared the town was indefensible due to its terrain. He ordered bridges destroyed and equipment removed before retreating to Winchester. Patterson stayed along the Potomac River instead of chasing him. The two armies watched each other for weeks without major conflict. They fought once at Falling Waters on July 2. Patterson advanced toward Winchester but stopped after moving only partway. His officers advised caution while some regiments refused to stay longer. These factors convinced Patterson to cancel his advance entirely.
Johnston received orders on July 18 to move his army to reinforce P. G. T. Beauregard at Manassas Junction. Movement began that evening with each brigade marching to Piedmont. There they boarded trains bound for Manassas Junction. Only one train existed on the Manassas Gap Railroad so units arrived sequentially. Artillery and cavalry marched overland instead of using rail transport. Final units reached their destination on the afternoon of July 21. This logistical effort required precise coordination between multiple commands and limited resources available during wartime conditions.
McDowell launched an attack on the Confederate left wing on the morning of July 21. Fighting escalated across Matthews Hill and Henry House Hill as more brigades joined the fray. All four of Johnston's brigades plus four from Beauregard's eight engaged in this area. Jackson earned his nickname "Stonewall" while defending Henry House Hill. Thomas J. Jackson himself was wounded during the battle alongside other key commanders. Francis Bartow died leading his Georgia troops while Barnard E. Bee also fell in combat. Edmund Kirby Smith sustained injuries but remained active throughout the engagement.
Johnston and Beauregard merged their commands into the Department of Northern Virginia after the battle. Their combined force adopted the name Army of the Potomac. Johnston retained overall command with Beauregard serving second until transferred westward. This consolidation marked the end of the Army of the Shenandoah as a distinct entity. The newly formed department would face future challenges under unified leadership. Historical records show how these early organizational changes shaped subsequent campaigns in Virginia.
