Fort Edward Johnson was a series of Confederate States of America (CSA) military breastworks constructed in April 1862 by the four-thousand member brigade known as the "Army of the Northwest". The Army of the Northwest was a remnant of the Confederate Army of the Northwest which had been disbanded in February 1862. The Army of the Northwest was commanded by Colonel Edward "Alleghany" Johnson and had been ordered to secure a major roadway through the Appalachian Mountains known as the Staunton and Parkersburg Turnpike. Johnson ordered the construction of fortifications and breastworks at a high point along the turnpike on top of Shenandoah Mountain, which is in the U.S. state of Virginia, 26 miles (42 km) west of Staunton.
