Anti-Communist League of the Caribbean

The Anti-Communist League of the Caribbean also known as the Anti-Communist Legion of the Caribbean was an anti-Castro rightist group based in the Dominican Republic funded by the dictators Rafael Trujillo of the Dominican Republic, Anastasio Somoza of Nicaragua and former Cuban Secret Police Chief Orlando Piedra. The purpose of the group was to overthrow the government of Fidel Castro in Cuba. The group eventually became part of the World Anti-Communist League in 1967.

The group was made up of Spaniards, Cubans, Croatians, Germans, Greeks and right-wing mercenaries trained in the Dominican Republic. The group staged a failed attempt to overthrow Castro in 1958.

The headquarters of the Anti-Communist League was at one time located at Guy Banister's New Orleans office. The same location appeared on Fair Play for Cuba Committee leaflets distributed by Lee Harvey Oswald and such references to the league are often made in texts concerning conspiracy theories relating to Kennedy assassination.

Former FBI employee William Turner states in Rearview Mirror (2001) that Guy Banister headed the ACLC after he came to New Orleans in 1955 and that Banister's deputy Hugh F. Ward was also a member of the ACLC as well as Maurice Brooks Gatlin, Sr an attorney who served as a legal counsel to the group. Turner states that the ACLC acted as an intermediary between the CIA and rightist insurgency groups in the Caribbean, including Cuba after Castro gained power. Turner also quotes the view of Jerry Milton Brooks, a former Minuteman and employee of Guy Banister, who states that the Anti-Communist League with the help of the CIA was responsible for the overthrow of the leftist Arbenz government in Guatemala.
