The 2 inch caliber gun (C19) was loaded with, in addition to a powder cartridge and wads, a 1.81inch diameter cast iron ball and three wrought iron bolts bundled together to form a roughly cylindrical projectile about 8 inches in length. The 18th century term for ammunition formed of bundled bolts was "langrage." Falconer's Marine Dictionary (1780:171) states:
"This contrivance is particularly designed to wound or carry away masts, or tear the sails and rigging of the adversary, so as to disable him from flight or pursuit. It is never used in royal ships, but very often by privateers and merchantmen".
