Book II Print 30: Rebel communications center and field hospital; Fidel Castro at La Plata headquarters.Yale University. Department of Manuscripts and ArchivesundatedengspaFidel Castro inside rebel communications center, under command of very efficient officer, Cdte. Waldo Fernandez (frames 9-12, et seq.). This radio tower had several call signs - RR1, i.e. "Radio Rebelde Uno," also RR7; by the fall of 1958 (date of this photo), it had become the guerrilla forces' principal communications and propaganda lifeline. Frames 19-24 show the field hospital adjoining La Plata headquarters, then under command of Dr. Rene Vallejo and Dr. Bernade Ordaz, the Hospital Mario Muniz. Note that according to strict rebel sanitary policy, local hill people and rebel troopers wait for treatment in this queue without discrimination. Rebels always extended medical services to civilians under their control: this became important source of local support. Other frames show Fidel at La Plata.
