The engineer dispatched by the CIA to liaise with Castillo Armas informed the CIA that Castillo Armas had the financial backing of Somoza and Trujillo. Truman thereupon authorized Operation PBFortune. When contacted by the CIA agent dispatched by Smith, Castillo Armas proposed a battle-plan to gain CIA support. This plan involved three forces invading Guatemala from Mexico, Honduras, and ElSalvador. These invasions were supposed to be supported by internal rebellions. King formulated a plan to provide Castillo Armas with $225,000 as well as weaponry and transportation. Somoza was involved in the scheme; the CIA also contacted Trujillo, and Marcos Pérez Jiménez, the US-supported right-wing dictator of Venezuela, who were both supportive, and agreed to contribute some funding. However, the coup attempt was terminated by Dean Acheson, the US Secretary of State, before it could be completed. Accounts of the final termination of the coup attempt vary: some argue that it was due to the US State Department discovering the coup, while others say that it was due to Somoza spreading information about the CIA's role in it, leading to the coup's cover being blown.
