Officially, the Army of Liberation was the handiwork of a former Guatemalan colonel named Carlos Castillo Armas, living in exile after attempting an earlier coup against his nation’s elected government. In reality, the “army” was a largely mercenary force of some four hundred bankrolled by the CIA, while the planning for their “invasion” had been conducted in Washington and at a secret CIA field headquarters at a military airfield in Opa-locka, Florida. Involved in every aspect of that planning had been Frank Wisner.
