were felt to be a threat to all of Central America. The Costa Ricans defeated Walker at the Battle of Santa Rosa and the Second Battle of Rivas. The beleaguered Walker sought to appeal to support in his native South by restoring slavery in Nicaragua, making English the official language, changing the immigration law to favor Americans, and declaring his ultimate intention was to bring Nicaragua into the United States as a slave state. By this point, Walker had thoroughly alienated public opinion in Nicaragua while he was besieged in Grenada by a coalition of Guatemalan, Salvadorian and Costa Rican troops. The decision by Henningsen to burn down Grenada enraged Nicaraguan people and in March 1857, Walker, with his dreams of an empire in tatters, fled Nicaragua. In the 1980s, one of the Reagan administration's foreign policy was to overthrow the left-wing Sandinista government by arming guerrillas known as the Contras. Between 1982 and 1984, Congress passed the three Boland amendments which limited the extent of American aid to the Contra rebels.

Owing to the legal problems posed by the Boland amendments, the Reagan administration turned to the self-proclaimed mercenaries to arm and train the Contra guerrillas. In 1984, the CIA created the Civilian Military Assistance (CMA) group to aid the Contras. The CMA were led by a white supremacist from Alabama named Tom Posey, who like all of the other members of the CMA were graduates of the mercenary training camps. John Negroponte, the American ambassador to Honduras, arranged for permission to be given for the CMA to operate from Honduran territory. However, the operation collapsed later in 1984 when the Nicaraguans shot down a CMA plane carrying arms to the Contras, killing two
