The Army of Virginia was organized as a major unit of the Union Army and operated briefly and unsuccessfully in 1862 in the American Civil War. It should not be confused with its principal opponent, the Confederate Army of Northern Virginia, commanded by Robert E. Lee.

History

The Army of Virginia was constituted on June 26, 1862, by General Orders Number 103, from four existing departments operating around Virginia: Maj. Gen. John C. Frémont's Mountain Department, Maj. Gen Irvin McDowell's Department of the Rappahannock, Maj. Gen. Nathaniel P. Banks's Department of the Shenandoah, and Brig. Gen. Samuel D. Sturgis 's brigade from the Military District of Washington. Maj. Gen. John Pope commanded the new organization, which was divided into three corps of over 50,000 men. Three corps of Maj. Gen. George B. McClellan's Army of the Potomac later were added for combat operations.

Banks' corps of the Army of Virginia fought with Stonewall Jackson at the Battle of Cedar Mountain, gaining initial advantage, but was defeated by a Confederate counterattack led by A.P. Hill. The entire army was soundly defeated at the Second Battle of Bull Run by Jackson, Longstreet, and Lee, and withdrew to the defensive lines of Washington, D.C.. On September 12, 1862, the units of the Army of Virginia were merged into the Army of the Potomac and the Army of Virginia was never reconstituted.
