A military invasion of Cuba by a CIA sponsored group took place in April 1961. Known as the Bay of Pigs Invasion after a bay in southern Cuba, it was thwarted by the Cuban armed forces in three days. The failure of Bay of Pigs Invasion strengthened the position of Cuban PM Fidel Castro and was an embarrassment for the US government led by John F. Kennedy. It also strengthened Cuba’s ties with the Soviet Union and made Castro fear that a US invasion of Cuba was on the cards. US imposed embargo and continued covert operations against Castro’s government. All this contributed to the Cuban Missile Crisis.

The Soviet code name for the operation was Operation Anadyr.
