Cryptonym: SECANT

Return to Main Crypts Page

SECANT was the cryptonym for Major Enrique Trinidad Oliva. A CIA document in December, 1953, stated that SECANT was a retired Guatemalan Army Major residing in Guatemala City.
The report also added that SECANT maintained "numerous contacts and informants among his former associates in the armed forces. SECANT also acts as SEQUIN's adviser on all matters pertaining to military intelligence."

A cable on 23 January, 1954, mentioned that the U.S. State Department on 22nd January stated that SECANT was under arrest and SEQUIN's house had been searched by police. A "well informed source in opposition" apparently remarked that the arrest of SECANT was a "severe blow to the anti-government movement, as he was a key figure and could implicate others if forced talk." Another cable on 23 January, 1954, stated that the press had reported the arrest of Major Enrique Oliva, who was described as "(inactive)" of the Guatemalan Army. The cable also stated that Oliva was one of the most important leaders of the Calligeris group, and if he talked it could lead to the arrest of others.

A cable on February 13, 1954, mentioned that "Oliva confidentially told Mario Rivas Montes he was given water treatment while in custody authorities." A dispatch on 23 February, 1954, stated that SECANT was still in Guatemala and "reportedly he received the water treatment."

Moreover, Matthew Ontrich (Nestor Sanchez) complied an interrogation report on SECANT and SEMANTIC in April of 1954 which stated that the latter "made a very good impression on Ontrich, Cadick (William Robertson) and Lugton with their detailed knowledge of the internal Guatemalan situation and their optimism on being able to carry out the job."

A dispatch on 16 May, 1954, mentioned that Clower (Joseph G. Sancho) was the case officer of ESCOBILLA, SEMANTIC and SECANT. Also, cables in June, 1954, stated that SECANT had taken refuge in the El Salvador Embassy in Guatemala City. A cable from William Robertson on 20 June stated that SECANT and/or SEMANTIC would probably accompany Carlos Castillo Armas during his invasion of Guatemala.

04/25/54: Debriefing by Ontrich of SEMANTIC and SECANT: "The debriefing of SEMANTIC and SECANT was very revealing and satisfactory especially after both cleared the LCFLUTTER (Note: Polygraph - "lie detector" - testing). The first basic issue which had to be clarified was the degree of compromise caused by the January torture and interrogation of SECANT. The interrogation by Ontrich (Nestor Sanchez) and a check on the LCFLUTTER revealed no compromise of any assets. The main topic the Guatemalan Police hampered on throughout the interrogation was of a plot against the government by SECANT and ESODIC-1. No mention was even made in the interrogation about Calligeris (Carlos Castillo Armas). Since there was absolutely no truth in this story SECANT was on solid ground throughout the torture and interrogation. After this point was clarified and Calligeris, SECANT and SEMANTIC cleared the LCFLUTTER a detailed debriefing commenced on the internal assets of the Calligeris organization. SECANT and SEMANTIC provided facts, figures and names of leaders, potential leaders and followers in the 9 important areas... Although these people have not received any formal training in clandestine tradecraft it is remarkable what they know and how fast they pick up new ideas. The military angle of the operation was discussed in detail with SECANT and Calligeris. The internal Guatemala PM assets look fairly good...SEMANTIC and SECANT made a very good impression on Ontrich, Cadick (William Robertson) and Lugton with their detailed knowledge of the internal Guatemalan situation and their optimism on being able to carry out the job." - - - SECANT's interrogation by Ontrich is contained in this document, pages 4-8: https://www.cia.gov/readingroom/docs/DOC_0000916781.pdf
