In 1742, Englishman Benjamin Robins wrote New Principles of Gunnery where he added science to the field of ballistics. He developed carronades which were short, lightweight muzzleloading smoothbore cannons that could be used on the decks of ships. During the American Revolutionary War, the British had a number of different cannons as well as mortars. Many of the American weapons were captured British cannon.
