We marched next day towards the city of Cuernabaca or Quauhnahuac. The Mexicans who occupied that place came out to fight us, but were soon defeated and pursued to Teputztlan or Tepatlan, which we took by storm, and made a considerable booty of Indian women and other spoils. Cortes summoned the chiefs of this place to come in and submit; and on their refusal, and on-purpose to impress the inhabitants of other places with terror, he ordered about the half of this town to be set on fire. At this time, the chiefs of a town called Yauhtepec came to Cortes and made their submission. Next day, we returned to Cuernabaca, which is a large town in a very strong situation, being defended by a deep ravine with a small rivulet, which precludes all access except by two bridges, which the inhabitants had broken down on our approach. Cortes was informed of a ford about half a league above the town which was practicable for the cavalry, to which he marched, by which the main strength of the enemy was drawn off to oppose him. We of the infantry searched for means to pass the ravine, and at length discovered a very dangerous pass by means of some trees which hung over from both sides, by the help of which about thirty of us and a considerable number of our Tlascalan allies got across. Three fell into the ravine, one of whom broke his leg. It was a most terrifying passage, and at one time I was quite blind with giddiness. Having got over and formed, we fell unexpectedly on the flank and rear of the enemy, and being now joined by a party of the cavalry, we soon drove the enemy from the field into the neighbouring woods and rocks. We found considerable property in the town, and we were here all lodged in the buildings of a large garden belonging to the cacique of the district. A deputation of twenty of the chiefs of the Tlahuican nation now waited on Cortes, offering to submit their whole country to his authority, and threw all the blame of their hostilities on the Mexicans.
The object of our next march was against Xochimilco, a large city on the fresh water lake of Chalco, in which most of the houses are built. As it was late before we left Quauhnahuac, and the weather was exceedingly sultry, our troops suffered excessively for want of water, which was not to be procured on our route. Many of our allies fainted, and one of them, and also one of our soldiers died of thirst. Seeing the distress of the army, Cortes ordered a halt in a pine forest, and sent forwards a party in search of relief. As I saw my friend De Oli about
