Fort Haggerty
Here beside the Georgetown-Alexandria road stood Fort Haggerty, a small outwork of Fort Corcoran, constructed in May 1861. With a perimeter of 128 yards and emplacements for 4 guns, it was designed to bring under fire the slope south of Fort Corcoran, which could not be seen from there.
