The Ñancahuazú Guerrilla or Ejército de Liberación Nacional de Bolivia (ELN) was a group of mainly Bolivian and Cuban guerrillas led by the guerrilla leader Che Guevara which was active in the  Cordillera Province, Bolivia from 1966 to 1967. The guerrilla was intended to work as a foco, a point of armed resistance to be used as a first step to overthrow the Bolivian government and create a socialist state. The guerrillas successfully defeated several Bolivian patrols before they were wiped out and Guevara captured and executed. Only five guerrillas managed to survive and flee to Chile.
