The lunette stood less than a mile away from Arlington House, the Union-occupied estate of Confederate General Robert E. Lee. It remained in use throughout the war.
Constructed on local farmland in August 1861, the lunette was named for Lt. Presley O. Craig, 2nd U.S. Artillery Regiment, who was killed at the First Battle of Bull Run on July 21, 1861. Oriented to the southwest, it had a perimeter of 324 yards, emplacements for 11 guns, and 2 magazines. The fort's armament included four 24-pound guns, one 24-pound field howitzer, five 30-pound Parrott rifles, a 10-inch mortar, and a 24-pound Coehorn mortar.[2]
In June 1865, Fort Craig was ordered dismantled and the site returned to its previous owners.[3] No trace of the lunette remains today in what has become a residential area. A historic marker, near the intersection of South Courthouse Road and 4th Street South in Arlington, shows the location where the lunette once stood. The marker depicts the fort's position on a map of the city's defenses and reads: Here stood Fort Craig, a lunette in the Arlington Line constructed in August 1861. It had a perimeter of 324 yards and emplacements for 11 guns.[4]
