What was the purpose of the Bay Of Pigs?

In 1961 the United States sent trained Cuban exiles to Cuba to try and overthrow Fidel Castro's government ... The invasion is considered part of the Cold War because the United States was trying to prevent communism from taking hold in the Americas.

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, the operation took place at the height of the Cold War and its failure led to major shifts in international relations between Cuba, the United States, and the Soviet Union.
