Cannon were first mounted on Brimstone Hill in 1689 during the Nine Years' War, by Jean-Baptiste du Casse, when the French used them to capture the English Fort Charles. The English, under Sir Christopher Codrington, used the same tactic to recapture the fort a year later. From then on, the English used the hill as a fortress, mounting 24-pound cannon, taking advantage of its 972 foot height.[1]
