Over 1,400 paramilitaries, divided into five infantry battalions and one paratrooper battalion, assembled and launched from Guatemala and Nicaragua by boat on 17 April 1961. Two days earlier, eight CIA-supplied B-26 bombers had attacked Cuban airfields and then returned to the U.S. On the night of 17 April, the main invasion force landed on the beach at Playa Girón in the Bay of Pigs, where it overwhelmed a local revolutionary militia. Initially, José Ramón Fernández led the Cuban Revolutionary Army counter-offensive; later, Castro took personal control. As the invasion force lost the strategic initiative, the international community found out about the invasion, and U.S. President John F. Kennedy decided to withhold further air support. The plan, devised during Eisenhower's presidency, had required the involvement of U.S. air and naval forces. Without further air support, the invasion was being conducted with fewer forces than the CIA had deemed necessary. The invading force was defeated within three days by the Cuban Revolutionary Armed Forces (Spanish: Fuerzas Armadas Revolucionarias – FAR) and surrendered on 20 April. Most of the surrendered counter-revolutionary troops were publicly interrogated and put into Cuban prisons.
