The massive cannon seen in both pictures defended Fort Fisher at Wilmington, North Carolina, until, on January 15, 1865, the fort fell to a day-long bombardment and attack by Union Army and Navy forces led by Adm. David Porter. The victory meant that Wilmington, the last deep-water port for blockade runners, was now closed to the Confederacy. Not long after, the victorious army brought the gun to the United States Military Academy at West Point, where it was photographed in 1865 in the yard of the old Ordnance Compound. In the picture at the left the two fellows lounging against it—enlisted men from the Ordnance Detachment—seem not at all awed by the power and size of this beast—one of the most formidable guns in the service of the South, the historian William C. Davis has called it, capable of firing its 150-pound projectile over four miles, its barrel reinforced with iron sleeves to protect against the ferocious oressure created bv the powder charge.
