Little by little we started to feel very far away from everything. We could start imagining the guerrilleros walking around us, hidden behind the bushes, suffering but leading with determination, their revolution. Contemplating the vastness of the surroundings, the mountains quasi inhospitable and the very rare inhabited or cultivated areas; we wondered how such a small group of men could hope to conquer and dominate a so immense and hostile territory… In addition to this geographic difficulty, we know that the guerrilla had also to face a human problem. Contrary to Cuba, the guerrilleros did not have the support of the peasants who were afraid of them and whom they had to endeavour to convince (in vain). Instead of supplying them with goods and support, informing them or joining their forces, the inhabitants of the countryside avoid them or worse went up to denouncing them… It is for the guerrilleros an important handicap. Due to the lack of food and the ground inhospitality, the guerrilleros quickly turned exhausted, thirsty and starving, and went so down that even had to drink their own urine or eat their horses. Also deprived of any the communication with outside, we wonder how the revolution of Che Guevara could finally have triumphed…
