Book II Print 34: Activities along approach to Fidel Castro's headquartersYale University. Department of Manuscripts and ArchivesundatedengspaThis sheet was photographed along the approach route to Fidel Castro's headquarters near La Plata. Lt. Vilo Acuna testing his homemade rebel rifle grenade launcher (frames 3-10; See also Print 18.). Frames 12-18: Rebel requisitioned road grader with its proud guerrilla crew. Among approach routes to central guerrilla areas - the approach routes through foothills - growing rebel troop units were beginning to maintain roads, transfer points, supply dumps for gasoline and lubricants, and other semi-permanent installations designed to insure a predictable flow of military traffic through back roads of rebel zone. Frames 25-26 show Capt. Mario Hidalgo with his family. On right, youth in uniform is Mario's son, Hanibal Hidalgo, then photographer's travel aide. Note dog-tag hanging from Hanibal's neck: it was captured from government soldiers and laboriously re-engraved by hand, giving Hanibal much-wanted military appearance. Frames 32-37: Outside Fidel's headquarters hut at La Plata, the headquarters' dental officer, Dr. Enrique Borges, has his foot-operated drill and consulta.
