Circa 09/01/54: Index of De-briefing Reports: Pages 80-81: ANNEX F: TACTICAL INTELLIGENCE AND GENERAL by Withheld..."According to information which had been supplied by Calligeris (Carlos Castillo Armas), the entire intelligence organization within the target area was being run by SEQUIN, with the aid of SEMANTIC and SECANT (Major Enrique Trinidad Oliva). A closer study of the situation revealed, however, a picture that was somewhat different. SEQUIN's position at that time could be better defined as that of an administrative coordinator, not entirely responsible for intelligence, but also responsible for coordinating efforts along the PP and PM lines in the target area. SEQUIN's main contribution in the intelligence field was his handling of SLEEKER through SETTLER. The SLEEKER/SETTLER complex had been producing fairly well at that time, but it was felt that much of their production could have been obtained through overt sources...The three key Calligeris men in the target, SEMANTIC, SECANT and SEQUIN, all performed a multiplicity of functions. This not only had an adverse effect on security as far as compartmentation was concerned, but also created serious problems during the last few months of the operations, when the size and diversity of the jobs to be performed made it a humanly impossible task for these three men-and finally only SEMANTIC and SECANT - to be responsible for accomplishing the major part of the task which lay ahead..."
