Belle Plain Landing refers to a military camp established during the U.S. Civil War in Virginia. The camp was under the jurisdiction of the 15th New York Engineers, an infantry regiment that served in the Union Army. Located along the Potomac River, this encampment played a significant role in supporting the army's logistical needs and strategic operations. The Belle Plain Landing camp was one of many temporary military installations set up during the Civil War to accommodate troop movements and supply storage. Today, remnants of the camp may still be found at the Belle Plain State Park, providing a historical reminder of this significant period in American history.
