The Bay of Pigs Invasion was a failed landing operation on the southwestern coast of Cuba in 1961 by Cuban exiles who opposed Fidel Castro's Cuban Revolution, covertly financed and directed by the U.S. government
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, the main invasion force landed on the beach at Playa GirĂ³n in the Bay of Pigs, where it overwhelmed a local revolutionary militia.
The invading force had been defeated within three days by the Cuban Revolutionary Armed Forces and surrendered on 20 April. Most of the invading counter-revolutionary troops were publicly interrogated and put into Cuban prisons.
The invasion was a U.S. foreign policy failure. The invasion's defeat solidified Castro's role as a national hero and widened the political division between the two formerly-allied countries. It also pushed Cuba closer to the Soviet Union, setting the stage for the Cuban Missile Crisis in 1962.
