Book I Print 12: Early interdiction of trafficYale University. Department of Manuscripts and Archives1957 SeptemberengspaTaken in September of 1957, these images document a strategy of guerrilla warfare on which the rebels had, until that point, not generally relied. According to St. George, the strategy was to interdict traffic and burn the sugarcane fields in the immediate proximity of the highway. These sugarcane fields were located near Bayamo and the vehicles seized temporarily by the rebels include a bus, a taxicab and a truck. On this occasion, as St. George writes, the rebels "rode around, in and on [the vehicles] in great high spirits. Note this was a full year before the interdiction of all highway traffic within rebel reach became a matter of policy for Fidel; in consequence, none of the vehicles or civilians shown here suffered from their encounter with the barbudos."
