When the War of Jenkins' Ear (1739-1742) broke out, the Georgia leader marched into Florida at the head of 2000 British and Indian fighting men, captured the outlying forts, and in the bloodiest action of the campaign, destroyed the houses and fort of Mose. But when, after 37 days and the support of 7 ships, he was unable to breach the city walls, take the Castillo, or blockade the harbor, Oglethorpe withdrew (Sanchez Grinian, 1756). (Bushnell SS)
