Invasion Planning

CIA begins recruiting Cuban exiles for covert operation

1960

Under the Eisenhower administration, the CIA launched Operation Patsay to recruit and train Cuban exiles opposed to Castro. Recruits were drawn largely from Miami's exile community and screened for political reliability and military potential.

Exile brigade trains at bases in Guatemala

Nov 1960 - Apr 1961

CIA-trained Cuban exiles, organized into Brigade 2506, trained secretly at Retalhuleu and other bases in Guatemala under American instructors. The brigade received instruction in infantry tactics, amphibious landings, artillery, and airborne operations.

Operation Bumpy Road devised as invasion plan

Nov 1960

The overall invasion program, code-named Operation Bumpy Road, was developed by the CIA. It envisioned an amphibious landing establishing a beachhead in southern Cuba, followed by an airborne drop and a popular uprising against Castro that never materialized.

Kennedy authorizes the invasion plan

Apr 14, 1961

After months of internal debate, President Kennedy gave final approval for the invasion but scaled back direct American military involvement, canceling planned follow-up air strikes. This decision proved consequential when the landing force encountered fierce resistance.

The Invasion

Preliminary air strikes target Cuban airfields

Apr 15, 1961

Eight B-26 bombers painted to resemble Cuban Air Force aircraft attacked three Cuban airfields, destroying several planes. The strikes were intended to cripple Castro's airpower before the landing, though they failed to eliminate all combat aircraft.

Diplomatic protest at UN over air strikes

Apr 15, 1961

Adlai Stevenson, the US ambassador to the United Nations, publicly denied American involvement in the air strikes, presenting photographs of the camouflaged B-26s as evidence of defectors' missions. He was later humiliated when the deception was exposed.

Second air strike canceled amid diplomatic concerns

Apr 16, 1961

A crucial dawn air strike scheduled for April 16 was canceled by President Kennedy, who feared exposing American involvement and undermining the cover story. The cancellation left the invading brigade vulnerable to surviving Cuban aircraft and tanks.

Castro denounces attacks at funeral as 'American aggression'

Apr 16, 1961

At a public funeral for Cubans killed in the air raids, Fidel Castro declared that the revolution was socialist and denounced the bombings as American aggression. His speech galvanized Cuban defenses and confirmed the operation could not be disguised as an internal revolt.

Brigade 2506 lands at the Bay of Pigs

Apr 17, 1961

Shortly after midnight, approximately 1,400 members of Brigade 2506 came ashore at Playa Girón and Playa Larga on Cuba's southern coast. The landing site, chosen partly for its remoteness, featured treacherous reefs and dense swamps that hampered the assault from the start.

Sinking of supply ships Houston and Río Escondido

Apr 17, 1961

Cuban Air Force aircraft sank the ships Houston and Río Escondido, destroying much of the brigade's ammunition, communications equipment, and supplies. The losses crippled the invasion force's ability to sustain operations on the beachhead.

Paratroop drops secure roads near the beachhead

Apr 17, 1961

Brigade paratroopers dropped behind the beaches to block roads leading to the landing zones. They initially succeeded in delaying Cuban militia advances at San Blas and Palpite, buying time for the main force before being overwhelmed by superior numbers.

Battle of Playa Larga

Apr 17, 1961 - Apr 18, 1961

At Playa Larga, Brigade 2506 fighters held off waves of Cuban militia and regular troops for nearly a day. Facing relentless bombardment and dwindling ammunition, the defenders withdrew southward toward Playa Girón, inflicting heavy casualties along the way.

US Navy presence withheld from direct intervention

Apr 17, 1961 - Apr 20, 1961

Although American naval vessels stood offshore, President Kennedy refused to authorize direct combat intervention to save the brigade. Frustration among commanders and pilots mounted as requests for air cover were denied, sealing the invasion's fate.

Final stand at Playa Girón

Apr 18, 1961 - Apr 19, 1961

The remnants of Brigade 2506 made their last stand at Playa Girón against Cuban tanks, artillery, and infantry. Cut off from resupply and reinforcement, the exhausted brigade ran out of ammunition by midday on April 19, ending effective resistance.

Four American pilots killed supporting the brigade

Apr 19, 1961

On the final day, four American civilian pilots flying supply and cover missions for the CIA were shot down over Cuba and killed. Their deaths underscored the depth of covert American involvement despite official denials.

Invasion collapses; brigade defeated within three days

Apr 19, 1961

By April 19, the invasion had collapsed completely. Of roughly 1,400 men who landed, more than 100 were killed and over 1,200 captured. Castro's forces suffered far fewer casualties, and the operation ended in humiliating failure for the United States.

Aftermath and Legacy

Over 1,200 brigade prisoners taken captive

Apr 19, 1961

Approximately 1,202 captured members of Brigade 2506 were imprisoned in Cuba, where many endured harsh conditions and interrogations. Their families formed committees to press for release, turning the prisoners into a prolonged political issue in the United States.

Castro announces victory over invading forces

Apr 20, 1961

Fidel Castro personally took command of Cuban forces during the battle and proclaimed victory, declaring that the revolution had defeated 'Yankee imperialism.' The triumph cemented his authority and rallied domestic support around his government.

Kennedy publicly accepts responsibility for failure

Apr 21, 1961

President Kennedy addressed the American Society of Newspaper Editors and acknowledged sole responsibility for the failed operation, stating that victory had a hundred fathers and defeat is an orphan. Despite the fiasco, his approval ratings rose in subsequent polls.

Cuba declares itself a socialist state

May 1, 1961

Riding the wave of nationalist unity after repelling the invasion, Castro formally declared Cuba a socialist state. The announcement eliminated any pretense of ideological neutrality and accelerated Cuba's integration into the Soviet sphere.

Soviet Union deepens military ties with Cuba

Aug 1961

Spurred by the invasion threat, Soviet leader Nikita Khrushchev expanded military aid to Cuba, stationing advisors and defensive weapons on the island. This growing commitment set the stage for the deployment of nuclear missiles the following year.

Operation Mongoose launched to undermine Castro

Nov 30, 1961

Following the Bay of Pigs failure, President Kennedy authorized Operation Mongoose, a covert campaign of sabotage, propaganda, and assassination plots aimed at destabilizing Castro's government. The program intensified rather than ended American efforts against Cuba.

Cuban Missile Crisis erupts over Soviet missiles

Oct 16, 1962 - Oct 28, 1962

The discovery of Soviet nuclear missiles in Cuba brought the world to the brink of nuclear war. Kennedy imposed a naval quarantine and negotiated with Khrushchev until the Soviets agreed to withdraw the missiles, partially resolving the crisis the Bay of Pigs helped precipitate.

Prisoners ransomed for food and medical supplies

Dec 29, 1962

After lengthy negotiations brokered through lawyers including James Donovan, Castro released most of the imprisoned brigade members in exchange for $53 million worth of food, medicine, and tractors. The freed men returned to Miami, where Kennedy greeted them at the Orange Bowl.

Bay of Pigs becomes enduring symbol of covert policy failure

1963

Historians have long cited the Bay of Pigs as a cautionary example of flawed groupthink, poor intelligence, and overreliance on covert action. The disaster shaped later decisions during the Cuban Missile Crisis, when Kennedy deliberately sought broader counsel through the ExComm process.
