What hat role did us military action play during the communist revolution in cuba?

In August of 1959 the dictator of the Dominican Republic, Rafael Trujillo, with support from the United States, ordered the first invasion of Cuba, through the Anti-Communist Caribbean Legion, which ended in failure. The United States, through the CIA, promoted the organization of anti-Castro guerrilla groups in the Sierra del Escambray, which were nevertheless liquidated by battalions of workers and peasants organized in militias. The last band of "elevations" was annihilated in 1965.
