    Two Cubans charged with terrorizing other exiles in Miami to finance their continuing war against Castro go on trial in federal court here MOnday.
    Dr. Orlando Bosch, 40, the former pediatrician who heads the Revolutionary Recovery Insurrectional Movement (MIRR), and his MIRR lieutenant, Marcelino Garcia Jimenez, 58, are charged with three counts of extortion and one of conspiracy.
    Three letters in Spanish were received in late 1964 by Miami architect Alberto Badia, Miami Beach bank employee Roberto Mendoza and Clewiston Rancher Julio Iglesias, who fled to his ranch after a bomb was exploded outside his Fort Lauderdale home.
    The unsigned letters were typewritten in Spanish.  The government will try to prove that Bosch and Garcia followed up the threats with personal visits.
    In one of the letters the writer demanded Iglesias pay $10,000 into a $100,000 fund "for one series of operations on a grand scale that we hope will overthrow (Castro) drive him to the point of suicide including a possible assassination of Castro." (sic)
    "We are not playing games." the writer said.
    The letter to Iglesias described how a bomb, one pound of the high explosive Pentolite, was placed "one meter" from the garage door of his home at 2535 Laguna Dr., Fort Lauderdale "to do as little damage as possible...as a warning."
    Iglesias moved after that explosion to his ranch and the letter-writer said he had been followed there, to Miami and to the colleges his daughters attend in the North.
    The letter said "If you denounce us to the FBI or give them a copy of this letter you do it at the cost of their lives and you will still have to pay the money."
    The letter said "We are not cowardly gangsters."
    In another letter sent to Badia, demanding $5,000, the writer said he was "coordinator of the military section of a secret organization."  He said the members were risking their lives..."not for ourselves, but for Cuba."
    There was a threat "to stop the warning bombings here."  Referring to "the bombing of J. Iglesias instead of one pound bomb we could have put down as many pounds to liquidate as many people as we would want to liquidate."
    "It doesn't matter what foolish precautions you take, like Iglesias," the letter said.  "When brave men take an oath nothing is difficult for them."
    The letter said Badia and the others "and your families" would be "decisively dead" if they didn't deliver the money.
    The letters said Badia "on two occasions had been a few yards form our machine guns with our cars in back of you and beside you in line."
    The men were to give all the money to Mendoza in $100 bills.  Mendoza was to take it to the bank where he worked, according to the letter he received and change it to $5, $10, and $20 bills.
    In all, $20,000 was demanded.
    Except for warning bombings no one was injured.  Badia's home in Coral Gables was sprayed with bullets by two men in a speeding car in 1964 in another extortion plot prior to this one.  THose men were captured by Coral Gables police.
    Both prisoners have histories of physical ailments which could complicate the trial, expected to last three days.  Garcia has heart trouble and was released without bond in custody of his son, Dr. Eduardo Garcia, 440 SW 3rd St.  Bosch suffers from a bleeding ulcer which delayed this trial last June.  He lives at 2121 SW 11 St.
    Melvyn Greenspahn is the attorney for both men.  Assistant U.S. Attorneys James Matthews and Morton Orbach will prosecute the case before U.S. Judge Charles B. Fulton.
    The men face 20 years in prison if they are convicted.
    Bosch was acquitted in Orlando June 4 on charges of plotting to export bombs for another Cuban raid.  He was convicted Oct. 5 in East Naples on a state charge of transporting explosives over the Tamiami Trial.  He has not been sentenced yet on that conviction.
    After Bosch was arrested in Hartford, Conn., Nov. 25, 1965 on the Miami extortion indictment the counter-revolutionary leader charged he was being persecuted by the FBI which, he said, had bugged the MIRR offices in Miami.  He went on a hunger strike then and later in the Orlando jail.
    Bosch and his wife, also a doctor, have five children.
