This approximately 10-foot-long 32-pounder gun was cast at the Columbia Foundry in Georgetown, D.C., for the United States Navy in 1821. It was originally part of the armament of the USS Columbia until the ship was decommissioned in 1848, after which the cannon was stored at the Norfolk Navy Yard. Confederate troops captured it there in 1861, and in the fall of that year it was moved to Fort Livingston, a masonry fortification that guarded the entrance to Barataria Bay on Grand Terre Island, Louisiana. The carriage on which the gun presently rests resembles a Navy truck carriage without the wheels. When transferred to Fort Livingston, the 32-pounder was mounted on a seacoast, front pintle, barrette carriage. The weight of the cannon is marked as 59.1.0, which translates to 6,636 pounds. It fired a 32-pound cannonball up to 1,901 yards, or two-thirds of a mile, with a six-pound charge of black powder.
