The Eisenhower administration had created a plan to overthrow Fidel Castro's regime in Cuba. Led by the Central Intelligence Agency (CIA), with help from the U.S. military, the plan was for an invasion of Cuba by a counter-revolutionary insurgency composed of U.S.-trained, anti-Castro Cuban exiles led by CIA paramilitary officers. The intention was to invade Cuba and instigate an uprising among the Cuban people, hoping to remove Castro from power. Kennedy approved the final invasion plan on April 4, 1961.
On 4 April 1961, President Kennedy then approved the Bay of Pigs plan (also known as Operation Zapata), because it had a sufficiently long airfield, it was farther away from large groups of civilians than the Trinidad plan, and it was less "noisy" militarily, which would make denial of direct US involvement more plausible. The invasion landing area was changed to beaches bordering the Bahía de Cochinos (Bay of Pigs) in Las Villas Province.
