sometimes consisted of free Blacks. These Black troops made a critical difference in the fighting in the swamps, and kept Marion's guerrillas effective even when many of his white troops were down with malaria or yellow fever. The first black American to fight in the Marines was John Martin, also known as Keto, the slave of a Delaware man, recruited in April 1776 without his owner's permission by Captain of the Marines Miles Pennington of the Continental brig USS Reprisal. Martin served with the Marine platoon on the Reprisal for a year and a half and took part in many ship-to-ship battles including boardings with hand-to-hand combat, but he was lost with the rest of his unit when the brig sank in October 1777. At least 12 other black men served with various American Marine units in 1776–1777; more may have been in service but not identified as blacks in the records. However, in 1798 when the United States Marine Corps (USMC) was officially re-instituted, Secretary of War James McHenry specified in its rules: "No Negro, Mulatto or Indian to be enlisted". Marine Commandant William Ward Burrows instructed his recruiters regarding USMC racial policy, "You can make use of Blacks and Mulattoes while you recruit, but you cannot enlist them." The policy was formulated to set a higher standard of unit cohesion for Marines, with the unit to be made up of only one race, so that the members would remain loyal, maintain shipboard discipline and help put down mutinies. The USMC maintained this policy until 1942. War of 1812 During the War of 1812, about one-quarter of the personnel in the American naval squadrons of the Battle of Lake Erie were black, and portrait renderings of the battle on the wall of the nation's Capitol and the rotunda of Ohio's Capitol show that blacks played a significant role in it. Hannibal Collins, a freed slave and Oliver Hazard Perry's personal servant, is thought to be the oarsman in William Henry Powell's Battle of Lake Erie. Collins earned his freedom as a veteran of the Revolutionary War, having fought in the Battle of Rhode Island. He accompanied Perry for the rest of Perry's naval career, and was with him at Perry's death in Trinidad in 1819. No legal restrictions regarding the enlistment of blacks were placed on the Navy because of its chronic shortage of manpower. The law of 1792,
