We began our March from Tlascala on the 26th of December 1520, with the whole of our Spanish force, and accompanied by ten thousand of our Tlascalan allies40, and halted that night within the territories of the state of Tezcuco, the inhabitants of which place supplied us with provisions. We marched about three leagues on the 27th, when we halted at the foot of a ridge of mountains, finding the weather extremely cold. Early next day we began to ascend the mountains, the bad roads having been made more difficult by the enemy, by means of ditches and felled trees, which were removed by the exertions of our allies. We proceeded with the utmost order and precaution, having an advanced guard of musketeers and crossbow-men, and our allies cleared the way to enable our cavalry to advance. After passing the summit of the mountain, we enjoyed the glorious prospect of the vale of Mexico below, with the lakes, the capital rising out of the waters, and all its numerous towns and cultivated fields; and gave thanks to GOD, who had enabled us again to behold this astonishing scene of riches and population, after passing through so many dangers. We could distinctly perceive numerous signals made by smoke in all the towns towards Mexico; and a little farther on, we were resisted by a body of the enemy, who endeavoured to defend a bad pass at a deep water-run, where the wooden bridge had been broken down; but we soon drove them away, and passed over, as the enemy contented themselves with shooting their arrows from a considerable distance. Our allies pillaged the country as we went along, which was contrary to the inclination of our general, but he was unable to restrain them. From some prisoners whom we had taken at the broken bridge, we were informed that a large body of the enemy was posted on our line of march, intending to give us battle; but it appeared afterwards that they had separated in consequence of dissentions among the chiefs, and we soon learnt that a civil war actually existed between the Mexicans and the state of Tezcuco. The small-pox also raged at this time in the country, which had a great effect in our favour, by preventing the enemy from being able to assemble their forces.

Next morning we proceeded on our march for Tezcuco, which was about two leagues from the place where we had halted for the night; but we had not proceeded far, when one of our patroles brought intelligence that several Indians were coming towards us bearing signals of peace, and indeed we found the whole country through which we marched this day in perfect tranquillity. On the arrival of the Indians, we found them to consist of seven chiefs from Tezcuco, sent as ambassadors by Coanacotzin, the prince of Tezcuco or Acolhuacan. A golden banner was carried before them on a long lance, which was lowered on approaching Cortes, to whom the ambassadors bowed themselves in token of respect. They then addressed our general in the name of their prince, inviting us to his city, and requesting to be received under our protection. They denied having taken any part in the attacks which we had experienced, earnestly entreating that no injury might be done to their city by our allies, and presented their golden banner to Cortes, in token of peace and submission. Three of these ambassadors were known to most of us, as they were relations of Montezuma, and had been captains of his guards, when we were formerly at Mexico. The ambassadors were assured by Cortes that he would use his utmost efforts to protect the country, although they must well know that above forty Spaniards and two hundred of our allies had been put to death in passing through their territories when we retreated from Mexico. Cortes added, that certainly no reparation could now be made for the loss of our men, but he expected they would restore the gold and other property which had been taken on that occasion. They asserted that the whole blame of that transaction was owing to Cuitlahuatzin, the successor of Montezuma, who had received the spoil and sacrificed the prisoners. Cortes found that very little satisfaction could be got from them for the past, yet wishing if possible to make them now our friends, he earnestly entreated the Tlascalan chiefs to prohibit their warriors from pillaging the country, and his wishes were strictly complied with, except in regard to provisions. After this conference was ended, we proceeded to a village named Guatinchan or Huexotla, at a small distance from Tezcuco, where we halted for the night.

Next morning, being the 31st December 1520, we marched into Tezcuco, where neither women or children were to be seen, and even the men had a suspicious appearance, indicating that some mischief was intended against us. We took up our quarters in some buildings which consisted of large halls and inclosed courts, and orders were issued that none of the soldiers were to go out of their quarters, and that all were to be on the alert to guard against surprize. On the soldiers being dismissed to their respective quarters, the Captains Alvarado and De Oli, with some soldiers, among whom I was, went up to the top of a lofty temple, from which we had a commanding view, to observe what was going on in the neighbourhood. We could see all the people everywhere in motion, carrying off their children and effects to the woods and the reedy borders of the lake, and to great numbers of canoes. Cortes wished to have secured Coanacotzin, who had sent us the friendly embassy, which now appeared to have been merely a pretext to gain time; but it was found that he and many of the principal persons of Tezcuco had fled to Mexico. We posted strong guards, therefore, in every direction, and kept ourselves in constant readiness for action. Cortes soon learnt that factions existed in Tezcuco, and that many of the chiefs were adverse to their present prince, and remained in their houses, while those of the opposite faction had withdrawn. Cortes sent for those chiefs next morning, from whom he learnt, that they considered their present prince, Coanacotzin, as an usurper, he having murdered his elder brother, Cuicutzcatzin, who had been placed on the throne by Montezuma and Cortes, and that Coanacotzin owed his elevation to the favour of Guatimotzin, the present sovereign of Mexico. They pointed out a youth named Ixtlilxochitl as the rightful heir of Acolhuacan, who was brought immediately to Cortes, and installed without delay in the government. Cortes prevailed upon him to become a Christian, and had him baptised with great solemnity, standing godfather on the occasion, and giving him his own name, Don Hernando Cortes Ixtlilxochitl; and to retain him in the Spanish interest and in our holy faith, he appointed three Spaniards to attend upon him, Escobar, who was made captain or governor of Tezcuco, Anthonio de Villa Real, and Pedro Sanches Farfan. In the next place, Cortes required the new prince of Tezcuco to supply him with a number of labourers to open up the canals leading to the lake, on purpose to admit our vessels which were to be put together at Tezcuco. He also informed him of our intentions to besiege Mexico, for which operation the young prince engaged to give all the assistance in his power. The work on the canals was conducted with all expedition, as we never had less than seven or eight thousand Indians employed41. As Guatimotzin, the reigning monarch of Mexico, frequently sent out large bodies of troops in canoes on the lake, apparently with the hope of attacking us unprepared, Cortes used every military precaution to guard against any sudden attack, by assigning proper posts to our several captains, with orders to be always on the alert. The people in Huexotla, a town and district only a few miles from Tezcuco, who had been guilty of murdering some of our countrymen on a former occasion, petitioned Cortes for pardon, and were taken into favour on promise of future fidelity.
