124-10221-10050: FBI REPORT: 30TH OF NOVEMBER REVOLUTIONARY MOVEMENT
04/29/63: FBI report from Robert James Dwyer of the Miami Office: ..."It is noted that previously on December 6, 1962, Cecilio Argelio Martinez del Toro advised that he was born November 22, 1927, had previously worked as a bookkeeper and resided with his wife and two children at 4737 Northwest 15th Court. He stated that he is the person responsible for the 'Wasp', a 31 foot prowler cabin cruiser, then presently located at Germain's Dock, Marathon, Florida. Martinez stated that Felipe Vidal, a Cuban exile, and Roy Emory Hargraves, an American Soldier of Fortune, active in Cuban revolutionary matters, have worked together but are not associated with the 30th of November Revolutionary Movement. Martinez said the 'Wasp' was used on a 30th of November mission to Cuba and Vidal participated as a navigator and brought along his friend Hargraves. Martinez explained that the group did not want Hargraves to come along, but in order to retain Vidal's services, they were forced to accept him. He said he knew the United States Government did not want American adventurers participating in raids against Cuba, but that Hargraves would not be taken along again and was not a member of the organization. Martinez said the "Wasp" is equipped with two VG gasoline engines which develop over 600 horsepower and the boat is fast and seaworthy."
