Book II Print 3: Advanced perimeter rebel post near SantiagoYale University. Department of Manuscripts and ArchivesundatedengspaThe first frames here (6-12) depict, much as Print 2 does, an advanced perimeter rebel post near Santiago, this one commanded by Cdte. Rene de los Santos (Frame 7, center, long raincoat) operating a radio transmission facility (RR12, that is Radio Rebelde Doce) and a relay point for couriers, supply runners, forward observation agents (i.e. spies). Frame 9 depicts such a function: a confidential personality en route to rebel headquarters (an operative or perhaps a minor local community leader committed to cooperation with the guerrillas) is passed through in a jeep blanketed with a large plastic shower curtain to keep the passenger invisible. Even the frames showing the stuck truck are illustrative: the favorite sport of rebel advance units was the acquisition and operation of motor transport, an enterprise they often attacked with more enthusiasm than expertise. Other frames show the photographer on the shore near the RR12 shortwave shack.
