southward migration of Seminoles and African Americans escaping the American advance. Members of the Colonial Marine battalion who were deployed on the Atlantic coast withdrew from American territory. They continued in British service as garrison-in-residence at Bermuda until 1816, when the unit was disbanded and the ex-Marines resettled on Trinidad. First Corps Rear Admiral Sir Alexander Cochrane raised the first Corps of Colonial Marines in 1808 while commander-in-chief of British naval forces on the Leeward Islands station during the Napoleonic Wars. The British had captured the island of Marie Galante earlier that year, but the French governor of Guadeloupe attacked the island on hearing that illness had weakened its British garrison. Marie Galante slaves assisted the British when promised that they would not be returned to their proprietors; by this means, the island was preserved under British control until the arrival of three companies of the 1st West India Regiment. Cochrane named the ex-slaves the Corps of Colonial Marines, which was enlarged with fugitive slaves from Guadeloupe. The Corps was paid from Marie Galante revenues, clothed from Royal Navy stores and commanded by Royal Marine officers. After the repossession of Guadeloupe Cochrane maintained the Corps, and on 12 October 1810 redistributed the men: 70 among the ships of the squadron, 20 to 30 to the battery at the Saintes (a group of small islands south of Guadeloupe) and 50 remaining in the Marie Galante garrison. They saw no further action as a distinct body, but were listed in ships' musters among supernumeraries for wages and victuals under the description "Colonial Marine" until mid-1815. Second Corps Cochrane, by now a Vice Admiral, assumed his position as Commander-in-Chief of British forces on the North Atlantic station in April 1814 and ordered the recruitment of a body of Colonial Marines as he had done six years earlier on Marie Galante. Rear Admiral George Cockburn, Cochrane's second-in-command on the Atlantic coast, implemented Cochrane's order recruiting the second Corps of Colonial Marines. It served as part of the British forces on the Atlantic and Gulf coasts of the United States during the War of 1812. On 2 April 1814, Cochrane issued a proclamation to all persons wishing to emigrate. Any persons would be received by the British, either at a military outpost or aboard British ships; those seeking sanctuary could enter His Majesty's forces, or go "as free settlers to the British possessions in North
