Careful research has gone into the casting, inscriptions and carriages of the recently cast fieldpieces, howitzers and mortars. Fort Ligonier features several cast bronze weapons including an eight-inch bronze howitzer and carriage, a light brass six pounder, and a fieldpiece which fired round shot, grape or canister, which is mounted on carriages with large wheels, in addition to gun sleighs and block carriages.
Six-Pound Field Piece
A 6-pounder throws a 6-pound ball. Used on the battlefield for easy mobility, this gun fires solid iron round shot, and for close range, anti-personnel grape shot and case shot. The elevating screw raises and lowers the bronze barrel. The piece has a range of 2,000 yards.
Five and a Half-Inch Howitzer
A howitzer combines the features of a mortar with a field piece. A carriage with large wheels and short trail, it discharges a 5 1/2 inch exploding shell and can also fire anti-personnel case and grape shot. The cast bronze barrel bears the cipher of Field Marshal John Ligonier, Lieutenant General of Ordnance at the time.
Twelve-Pound Field Piece
A light 12-pounder throws a 12-pound ball. Used on the battlefield, this gun fires solid iron round shot, grape shot and canister. The elevating screw raises and lowers the bronze barrel. The piece has a range of 2,000+ yards.
