Fort Runyon

A half-mile to the southwest stood Fort Runyon, a large bastioned earthwork constructed in May 1861 to protect the Long Bridge over the Potomac. Its perimeter, 1484 yards, was about the same as that of the Pentagon. After the construction of the Arlington Line two miles to the west, Fort Runyon fell into disuse. Nearby Fort Jackson, at the Virginia end of the Long Bridge, was no more than a checkpoint to control traffic on the bridge and protect it from sabotage.
