Confederate troops, the remnant of the Army of the Northwest commanded by Brig. Gen. Edward “Allegheny” Johnson, constructed this fortification about 1 Apr. 1862 to protect the Shenandoah Valley, the “Breadbasket of the Confederacy.” Federal troops briefly occupied the fort after he withdrew to West View near Staunton later that month. With Maj. Gen. Thomas J. “Stonewall” Jackson’s Army of the Shenandoah, Johnson’s command confronted Union forces under Brig. Gen. Robert H. Milroy and Brig. Gen. John C. Fremont at the Battle of McDowell on 8 May. Johnson’s ankle was shattered during this first victory in Jackson’s famous Valley campaign.
