May 30 1966 teletype from the CIA to the White House Situation Room: Guillermo Alvarez was one of the six commandos on the operation to kill Fidel led by Tony Cuesta and Herminio Diaz Garcia. His full name may have been Guillermo Alvarez Boucle, born in September 1933 in Cienfuegos, Cuba. Also see 1994.04.25.13:40:32:880005 Reel 5, Folder H - ANTONIO CUESTA DEL VALLE, p. 37, for the CIA Intelligence Information cable that copies most of this document. Also see 104-10169-10087, p. 4, which quotes Herminio Diaz Garcia (201-203040) in January 1966 stating that he and his group are ready to leave for Cuba to assassinate Fidel Castro. Also 124-10291-10330, p. 9, follow-up interview with Diaz that month where he said he was close with Efeginio Ameijeiras, Chief of the Cuban Revolutionary Police, who he hoped would agree to be the new leader of Cuba if Castro was killed.

Due to historiographic irony, Dr. Latell's gesture stirs the anniversary of May 29, 1966, which marks the fiasco of Commands L in his infiltration operation by Monte Barreto (Miramar). Soon the snipers fell Herminio Díaz and Armando Romero, who came to attack Castro as he passed through Fifth Avenue. The others managed to re-board, but about ten miles off the coast, near Jaimanitas, their 23-foot boat was intercepted by Komsomol torpedo boats and Guillermo Álvarez and Roberto Anta died in the naval skirmish. Tony Cuesta and Eugenio Zaldívar were arrested (and) badly wounded.. Tony Cuesta was blinded and mutilated. The retired general Fabián Escalante, ex-chief and current historian of State Security, narrates that he talked several times with Cuesta during his long time of rehabilitation and he always spoke very softly, with "a tremendous mystery, as if we were conspiring." In one of those conversations, the murder of JFK came out and Cuesta would have paled before revealing that on November 22, 1963, Cuban exiles Herminio Díaz and Eladio del Valle were in Dallas, Texas. When asking Escalante "if they participated in the murder", Cuesta "stands up and says that he cannot say more, that he can only say that, because he knows that it is an issue that interests us." An inmate who worked in the prison hospital and attended Cuesta, Reinaldo Martínez, called in 2007 George Robert Blakey, former Chief Counselor (1977-79) of the Select Committee of the House of Representatives on Murders (HSCA) English), to tell him that he had heard the same story, but "I had no evidence to know if Cuesta told the truth." Martínez added that he had known Herminio Díaz since he was a child and that, shortly after arriving in Miami around 1980, a common friend and anti-Castro veteran, Remigio “Cucú” Arce, had taken between drinks: “Hey, the one who killed President Kennedy was our friend Herminio.”

Continued from previous post: "Herminio Díaz's partner in Dallas —according to Cuesta— appeared on February 22, 1967 inside his red Cadillac in Miami with a shot to the heart, an ax blow to the head and signs of torture. Three days earlier, Eladio del Valle had identified a certain Manuel García González, also a Cuban exile, along with Lee Harvey Oswald in a photo shown to him by an investigator from Jim Garrison... And since there is no easy explanation for why Herminio Díaz landed in Cuba almost in front of the alert militiamen, Escalante infers that this action was one of two: 'a crazy thing or with a secret intention.'"
