The Bay of Pigs Invasion

The CIA was ready to give the Go signal to Tony Verona's contact, who would apparently be able to drop the botulinum poison in Castro's food. But this Go signal never came. At the very moment Verona was supposed to give the signal, he was being sequestered by another group of CIA agents unaware of Verona's crucial role in the hit. Richard Bissell says basically that he had hoped that Fidel Castro would have been dead by the time of the Bay of Pigs operation.
