Final answer:
The Bay of Pigs Invasion was an unsuccessful attempt by Cuban exiles trained by the CIA to overthrow Fidel Castro's government in Cuba, leading to their capture and later negotiations for release.
Step-by-step explanation:
The Bay of Pigs Invasion was a failed military action that occurred in April 1961. Named after the Bay of Pigs, where the invaders landed in Cuba, the mission aimed to overthrow the government of Fidel Castro. The invaders were a group of Cuban exiles trained by the CIA. Despite initial success against a local militia, they were unable to withstand the Cuban Army. The anticipated U.S. air support never came, resulting in the invaders' surrender. This event intensified the Cold War tensions and pushed Castro closer to the Soviet Union for protection.
Regarding the question, the invaders involved in the Bay of Pigs Invasion were captured and later negotiated for release. The operation exemplified the U.S. attempts to stop the spread of Communism during the Cold War and the challenges faced in counteracting the influence of the Soviet Union.
