Ejército de Bolivia
By Day 113, some of the guerrillas have deserted, and, upon capture, have led the Bolivian Army to the revolutionaries' base camp, which contained vast stockpiles of food, much-needed supplies, and intelligence identifying much of the group as Cubans. Much to Che's disappointment Tamara "Tania" Bunke, Guevara's revolutionary contact has botched elaborate preparations and given away their identity. On Day 141, the guerrillas capture Bolivian soldiers that refuse to join the revolution and are free to return to their villages. CIA and US Army Special Forces advisers arrive to supervise anti-insurgent activity and to train the Bolivian Army. On Day 169, Guevara's visiting friend, the French intellectual Régis Debray, is captured at Muyupampa by the Bolivian Army along with two of Che's last contacts with the outside world. A Bolivian airstrike then occurs against Che's guerrillas on Day 219, driving them deeper into hiding. By this time, Che has split his forces; his best fighters travel with him in one column, while another column contains other personnel, including Tania, and carries much of the remaining supplies.
