Militant anti-Castro groups, funded by exiles, by the Central Intelligence Agency (CIA) and by Rafael Trujillo's Dominican government, carried out armed attacks and set up guerrilla bases in the Escambray Mountains. This led to a failed rebellion, which lasted longer and involved more soldiers than the Cuban Revolution. Near 1,000 families were forcibly uprooted from the Escambray countryside, leaving the rebels without their habitat to support them; the uprooted men were sent to prisons and forced labor camps throughout Cuba.
