Bay of Pigs
The CIA trained Cuban exiles to bring down Fidel Castro's government. Fidel Castro was one of the people that led to the cuban revolution. They failed miserably. This is considered part of the Cold War because the US was preventing communism. The US planned an attack on Trinidad, but instead attacked at the Bay of Pigs on April 17, 1961. The soldiers landed in the swamps, and the planes crashed. The boats were sunk easily. It is said they failed because of the confusion over time zones.
