Cryptonym and pseudonym decoding sheet: On page 14 of 23, ESVEHICLE-1 is identified as General Ydigoras.
"On 26 July 1957 Arbenz was assassinated and the political situation in Guatemala evolved into a three-way dog fight among the forces of the left, the right, and the center...Ydigoras Fuentes -- the rightist candidate who also had the support of the Army...(after) a behind the scenes conference between Ydigoras and the MDN (Cruz Salazar's party), a deal was arranged where the assembly would elect Ydigoras and the MDN would get the three seats in the Cabinet (and other perks)."
"Cable, dated January 9, 1961, to JMBELL from Guatemala. This cable reads in part as follows: ESOLEO-1 was advised below-listed names provided by Guat secret service with statement they all Cubans except as noted who are on way or in Guat with (the) mission assassination (of) ESVEHICLE-1 and ESOLEO-1. (There follows a list of eight names.) This cable apparently reflects information received by the CIA that certain people in Guatemala were targets of Cuban assassination plots. I would speculate that the two acronyms, ESVEHICLE-1 and ESOLEO-1, refer to Cuban exile leaders who at that time were in training in Guatemala for the Bay of Pigs mission."
1/21/61 cable: Manuel Orellana Portillo is described in marginalia as a right-wing congressman and the president of the Anti-Communist Federation. Orellana, in the name of ESVEHICLE-1, invited AMDIP-1/Tony Varona to meet ESVEHICLE-1. ESVEHICLE-1 made it clear that Orellana did not represent him and he would not meet with anyone that Orellana had invited to meet with him. Marginalia describes ESVEHICLE-1 as "General Ydigoras".
4/17/61 Cable from JMBELL to Guatemala City: The CRC heads were cooped up in Opa-locka and "anxious (to) reach a zone of activity at earliest moment. Request you ask ESVEHICLE-1 (Guatemala President Miguel Ydigoras) permission (to) take them to JMADD or JMTRAV."
4/22/61: "The President: Asked about Guatemala and Nicaragua. Ydigoras is expected to have trouble. State (Dept.) thought he would, nevertheless, survive."
