Final answer:
A 1,400-strong army of Cuban exiles landed at D. the Bay of Pigs in April 1961, attempting to overthrow Fidel Castro's government in a failed covert operation known as the Bay of Pigs Invasion.
Step-by-step explanation:
In April of 1961, a 1,400-strong army of poorly-equipped Cuban exiles landed at D. the Bay of Pigs. This event is known as the Bay of Pigs Invasion, a failed covert operation that was initially planned by the Eisenhower administration and authorized by President Kennedy. The invasion aimed to overthrow Fidel Castro's government by arming and equipping Cuban refugees who were mainly supporters of the previous regime under Batista. However, the invasion ended in disaster as the United States withdrew promised air support, and the invaders could not garner the anticipated support from the Cuban populace or withstand the Cuban army's counterattack. Consequently, the invasion only strengthened Castro's position in Cuba and pushed him to seek Soviet protection.
