A few days after his last meeting with the CIA, Castillo Armas had led an assault against Matamoros along with a handful of supporters. The attack failed, and Castillo Armas was wounded and arrested. A year later, he bribed his way out of prison, and escaped back to Honduras. Castillo Armas's stories of his revolt and escape from prison proved popular among the right-wing exiles in Honduras. Among these people, Castillo Armas claimed to still have support among the army, and began planning another revolt. His reputation was inflated by stories that he had escaped from prison through a tunnel.
