The Bay of Pigs Invasion (Invasión de Bahía de Cochinos, sometimes called Invasión de Playa Girón or Batalla de Playa Girón after the Playa Girón) was a failed military landing operation on the southwestern coast of Cuba in 1961 by Cuban Democratic Revolutionary Front (DRF), consisting of Cuban exiles who opposed Fidel Castro's Cuban Revolution, covertly financed and directed by the U.S. government. The operation took place at the height of the Cold War, and its failure influenced relations between Cuba, the United States, and the Soviet Union.
In 1952, the American-allied dictator General Fulgencio Batista led a coup against President Carlos Prío and forced Prío into exile in Miami, Florida. Prío's exile inspired Castro's 26th of July Movement against Batista. The movement successfully completed the Cuban Revolution in December 1958. Castro nationalized American businesses, including banks, oil refineries, and sugar and coffee plantations. The Central Intelligence Agency (CIA) began planning the overthrow of Castro, which U.S. President Dwight D. Eisenhower approved in March 1960, and the U.S. began its embargo of the island. This led Castro to reach out to its Cold War rival, the Soviet Union, after which the US severed diplomatic relations. Cuban exiles who had moved to the U.S. following Castro's takeover had formed the counter-revolutionary military unit, Brigade 2506, which was the armed wing of the DRF. The CIA funded the brigade, which also included approximately 60 members of the Alabama Air National Guard, and trained the unit in Guatemala.
Over 1,400 paramilitaries, divided into five infantry battalions and one paratrooper battalion, assembled and launched from Guatemala and Nicaragua by boat on 17 April 1961. Two days earlier, eight CIA-supplied B-26 bombers had attacked Cuban airfields and then returned to the U.S. On the night of 17 April, the main invasion force landed on the beach at Playa Girón in the Bay of Pigs, where it overwhelmed a local revolutionary militia.
