Guarding the Cape Fear opposite and somewhat farther up-river from Battery Buchanan, Fort Anderson mounted mostly obsolete 32lb cannon. The garrison also possessed a 12lb Whitworth Rifle that proved more effective against Federal gunboats, but was short of ammunition. The massive earthwork, which extended landward along a series of flooded ponds, though not far enough to prevent a successful flanking maneuver by Federal forces under General Jacob Cox.
