The carronade was designed as a short-range naval weapon with a low muzzle velocity. Its invention is variously ascribed to Lieutenant General Robert Melville in 1759, or to Charles Gascoigne, manager of the Carron Company from 1769 to 1779. In its early years the weapon was sometimes called a "mellvinade" or alternatively, a "gasconade". Carronades initially became popular on British merchant ships during the American Revolutionary War. A lightweight gun that needed only a small gun crew and was devastating at short range was a weapon well suited to defending merchant ships against French and American Privateers.
