Inscription. 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.

Erected 1965 by Arlington County, Virginia. (Marker Number 5.)

Washington Forts. Built starting in May 1861, it was also among the first built. The Fort guarded the Virginia side of the Long Bridge (which crossed to the south of the modern railroad bridge). It also served to cover the Washington-Alexandria and Columbia Turnpikes.

As other forts were built and covered the approaches to sufficient depth, guns from Fort Runyon were relocated to more important sites. By the fall of 1862 it was being used more as a supply depot and corral. Armament was listed as one 8-inch seacoast howitzer and one 32-pdr gun at that time.

Units stationed at Fort Runyon over time included the 1st Massachusetts Heavy Artillery, 2nd, 3rd, and 21st New Jersey Infantry, 13th New Hampshire Infantry, and 7th New York Militia.

“This is from a sketch made by the author at the close of April, 1865, and shows the embankments of Fort Jackson on the right, and the remains of the pickets, with the railway, in the foreground. On the left is a public house of entertainment, and just beyond it is seen a portion of the Long Bridge. The Capitol is seen in the distance.” – B. J. Lossing.
