It was on one night in the early summer, having bid farewell to Otomie and taking my son with me, for he was now of an age when, according to the Indian customs, lads are brought face to face with the dangers of battle, that I despatched the appointed companies to their stations on the brow of the precipice, and sallied into the darksome mouth of the pass with the few hundred men who were left to me. I knew by my spies that the Spaniards who were encamped on the further side would attempt its passage an hour before the daylight, trusting to finding me asleep. And sure enough, on the following morning, so early that the first rays of the sun had not yet stained the lofty snows of the volcan Xaca that towered behind us, a distant murmuring which echoed through the silence of the night told me that the enemy had begun his march. I moved down the pass to meet him easily enough; there was no stone in it that was not known to me and my men. But with the Spaniards it was otherwise, for many of them were mounted, and moreover they dragged with them two carronades. Time upon time these heavy guns remained fast in the boulder-strewn roadway, for in the darkness the slaves who drew them could find no places for the wheels to run on, till in the end the captains of the army, unwilling to risk a fight at so great a disadvantage, ordered them to halt until the day broke. At length the dawn came, and the light fell dimly down the depths of the vast gulf, revealing the long ranks of the Spaniards clad in their bright armour, and the yet more brilliant thousands of their native allies, gorgeous in their painted helms and their glittering coats of feathers. They saw us also, and mocking at our poor array, their column twisted forward like some huge snake in the crack of a rock, till they came to within a hundred paces of us. Then the Spaniards raised their battle cry of Saint Peter, and lance at rest, they charged us with their horse. We met them with a rain of arrows that checked them a little, but not for long. Soon they were among us, driving us back at the point of their lances, and slaying many, for our Indian weapons could work little harm to men and horses clad in armour. Therefore we must fly, and indeed, flight was my plan, for by it I hoped to lead the foe to that part of the defile where the road was narrow and the cliffs sheer, and they might be crushed by the stones which should hail on them from above. All went well; we fled, the Spaniards followed flushed with victory, till they were fairly in the trap. Now a single boulder came rushing from on high, and falling on a horse, killed him, then rebounding, carried dismay and wounds to those behind. Another followed, and yet another, and I grew glad at heart, for it seemed to me that the danger was over, and that for the second time my strategy had succeeded.
