Inscription.
Positioned here at the end of a towering plateau, this fortification was the first earthen battery built on the mountain by the Federals in the fall of 1862. Facing south, its guns "commanded perfectly the summits of Loudoun Heights as well as Bolivar Heights."

A four-sided earthwork forms the dominant feature of this battery. Protecting its exterior slope is a dry moat - the widest, longest, and most uniform moat on the mountain. 30-pounder Parrotts were standard armament here.
