Bay of Pigs Invasion
The failed 1961 CIA invasion of Cuba by exiles, meant to topple Castro, that humiliated Kennedy and drove Cuba into Soviet arms.

In April 1961 a force of roughly 1,400 Cuban exiles, armed and trained by the CIA, waded ashore at a swampy inlet on Cuba's southern coast that the maps called the Bahia de Cochinos, the Bay of Pigs. The plan was to seize a beachhead, trigger a national uprising, and topple Fidel Castro within days. Instead the invaders were pinned on the sand and captured within seventy-two hours. The operation became one of the most studied fiascos in the history of American covert action: it humiliated a brand-new president, hardened Castro's revolution, and helped set the stage for the Cuban Missile Crisis the following year.
An operation nobody fully owned
The invasion was conceived under President Eisenhower, whose administration approved a CIA program to build and train an exile army in Guatemala. John F. Kennedy inherited the plan barely three months into his term. He approved it, but he hedged. Determined to preserve deniability, he insisted the American hand stay hidden, and after the first air raids on April 15 exposed the ruse (photographs showed US-supplied bombers clumsily painted in Cuban markings), he canceled the follow-up strikes meant to finish off Castro's air force. Those surviving planes would decide the battle. Each side also misread the other: the CIA assumed Kennedy would send in US forces rather than accept defeat, while Kennedy assumed the exiles could slip into the mountains as guerrillas if the landing failed. Neither assumption held.
Three days on the beach
The brigade came ashore on April 17 at Playa Giron and Playa Larga. Castro's surviving jets strafed the invaders and sank the freighters carrying their ammunition and radios. Castro himself rushed to the front, throwing some 20,000 troops, artillery, and tanks against the lightly supplied exiles. The promised uprising never came. By April 19 the brigade was out of ammunition and surrounded. More than a hundred exiles were killed, and nearly 1,200 surrendered. They spent twenty months in Cuban prisons until Washington quietly ransomed them in December 1962 for roughly 53 million dollars in baby food and medicine.
The reckoning
Kennedy took public responsibility, telling reporters that victory has a thousand fathers while defeat is an orphan. In private he was furious at the intelligence agency that had promised him a clean win. The consequences ran the opposite way from everything Washington intended. Castro used the invasion to rally Cubans, declared his revolution socialist, and moved openly into the Soviet embrace. Just as damaging, the debacle convinced Nikita Khrushchev that the young American president was inexperienced and could be pushed, an impression that emboldened the Soviet leader to test Kennedy over Berlin and, in 1962, to gamble on secretly planting nuclear missiles ninety miles from Florida. The invasion meant to end Castro's revolution instead let him nationalize it, and the president meant to look strong spent the next eighteen months proving he was not the pushover the Bay of Pigs had made him appear.
