<P> As armed conflict broke out in Cuba between rebels led by Fidel Castro and the Batista government, the U.S. was urged to end arms sales to Batista by Cuban president - in - waiting Manuel Urrutia Lleó . Washington made the critical move in March 1958 to prevent sales of rifles to Batista's forces, thus changing the course of the revolution irreversibly towards the rebels . The move was vehemently opposed by U.S. ambassador Earl E.T. Smith, and led U.S. State Department adviser William Wieland to lament that "I know Batista is considered by many as a son of a bitch...but American interests come first...at least he was our son of a bitch ." </P> <P> Until Castro, the U.S. was so overwhelmingly influential in Cuba that the American ambassador was the second most important man, sometimes even more important than the Cuban president . </P> <P> U.S. President Dwight D. Eisenhower officially recognized the new Cuban government after the 1959 Cuban Revolution which had overthrown the Batista government, but relations between the two governments deteriorated rapidly . Within days Earl E.T. Smith, U.S. Ambassador to Cuba, was replaced by Philip Bonsal . The U.S. government became increasingly concerned by Cuba's agrarian reforms and the nationalization of industries owned by U.S. citizens . Between 15 and 26 April 1959, Fidel Castro and a delegation of representatives visited the U.S. as guests of the Press Club . This visit was perceived by many as a charm offensive on the part of Castro and his recently initiated government, and his visit included laying a wreath at the Lincoln memorial . After a meeting between Castro and Vice-President Richard Nixon, where Castro outlined his reform plans for Cuba, the U.S. began to impose gradual trade restrictions on the island . On 4 September 1959, Ambassador Bonsal met with Cuban Premier Fidel Castro to express "serious concern at the treatment being given to American private interests in Cuba both agriculture and utilities ." </P> <P> The Escambray rebellion was a six - year rebellion (1959--1965) in the Escambray Mountains by a group of insurgents who opposed the Cuban government led by Fidel Castro . The rebelling group of insurgents was a mix of former Batista soldiers, local farmers, and former allied guerrillas who had fought alongside Castro against Batista during the Cuban Revolution . As state intervention and take - over of privately owned businesses continued, trade restrictions on Cuba increased . The U.S. stopped buying Cuban sugar and refused to supply its former trading partner with much needed oil, with a devastating effect on the island's economy, leading to Cuba turning to their newfound trading partner the Soviet Union for petroleum . In March 1960, tensions increased when the freighter La Coubre exploded in Havana Harbor, killing over 75 people . Fidel Castro blamed the United States and compared the incident to the sinking of the Maine, though admitting he could provide no evidence for his accusation . That same month, President Eisenhower quietly authorized the Central Intelligence Agency (CIA) to organize, train, and equip Cuban refugees as a guerrilla force to overthrow Castro . </P>
