U.S.A.

The Army of Virginia

Created to coordinate Union forces facing Jackson in the Shenandoah Valley and in the northern part of Virginia that had been threatening Washington, the army combined three existing departments and troops from a fourth* into three corps with a total strength of over 50,000 men.

The Army should not be confused with the Department of Virginia, a separate organization commanding part of Virginia around the mouth of Chesapeake Bay.
