The Battle of Aquia Creek was an exchange of cannon fire between Union Navy gunboats and Confederate shore batteries in Stafford County, Virginia which took place from May 29, 1861 to June 1, 1861 during the early days of the American Civil War. The Confederates set up several shore batteries to block Union military and commercial vessels from moving in the Chesapeake Bay and along the lower Potomac River as well as for defensive purposes. The battery at Aquia also was intended to protect the railroad terminal at that location. The Union forces sought to destroy or remove these batteries as part of the effort to blockade Confederate States coastal and Chesapeake Bay ports. The battle was tactically inconclusive. Each side inflicted little damage and no serious casualties on the other. The Union vessels were unable to dislodge the Confederates from their positions or to inflict serious casualties on their garrisons or serious damage to their batteries. The Confederates manning the batteries were unable to inflict serious casualties on the Union sailors or cause serious damage to the Union vessels. Soon after the battle, on Sunday, July 7, 1861, the Confederates first used naval mines, unsuccessfully, off the Aquia Landing batteries. The Confederates ultimately abandoned the batteries on March 9, 1862 as they moved forces to meet the threat created by the Union Army's Peninsula Campaign.
