Information of all this was previously conveyed to the inhabitants of Chalco by some trustworthy men of Tezcuco, that they might fall upon the Mexicans at the same moment with our troops. Nothing could have been more agreeable to the wishes of the inhabitants of Chalco, and they accordingly held themselves in readiness to rise up against the enemy at the proper time.
Sandoval composed his rearguard of five horse, an equal number of crossbow-men, and the greater part of the Tlascallans, who had all their booty with them. As the Mexicans had everywhere sent out scouts and spies to watch our movements, our present march to Chalco was no secret to them. They had therefore collected a strong body of their troops, and fell upon our rearguard, which was chiefly composed of Tlascallans. It may easily be supposed that our five horse and few crossbow-men could not stand long against these overpowering numbers; two were very soon killed, and the rest wounded. Sandoval had indeed hastened to their assistance with the first alarm, had succeeded in driving back the Mexicans, and killing seven of their men; yet they managed to gain their canoes, and retreat to a place of safety, which was the more easy for them to do, as the whole of the population of this district was subject to the Mexicans.
Sandoval was uncommonly vexed when he found the five horses and their riders covered with wounds, two crossbow-men killed, and the rest all wounded. He severely reproached them for not having defended themselves better, and for the little protection they had proved to our Tlascallan friends. He could easily see, he added, that they had but recently arrived from Spain, and knew very little about fighting.
His first care now was to provide for the safety of the Tlascallans and their baggage, and to despatch the letters Cortes had given him to Vera Cruz. In these letters our general had given the commandant of that town an account of all our conquests, and of his determination to besiege Mexico, and blockade it on all sides; the letter closed by desiring him to observe the utmost vigilance, and with orders to send all those of his men who were sufficiently strong for service to Tlascalla, where they were to remain until the road should be cleared of the enemy.
After Sandoval had despatched his messengers with these letters, and conducted our Tlascallan friends to where they were out of the enemy's reach, he marched back to Chalco, which was not very far distant. On this march he was particularly on his guard, since he was well aware that Mexican troops were lurking about in all directions, and lay concealed in every house. He had indeed not advanced far along a level tract of country, covered with maguey and maise plantations, before he was vigorously attacked. The enemy, on this occasion, carried, besides their usual weapons, long pikes, which were especially intended against the charge of our horse upon their line. Sandoval, however, twice broke through their dense ranks, and, with the Spanish troops and small body of allies we had still left, he drove the enemy completely out of the field. Five Spaniards, six horses, and many of our allies, were wounded. This time the enemy received a severe retribution for the fresh attack they made upon our troops; and, among the eight prisoners which were made, three were Mexicans of distinction.
When the inhabitants of Chalco, which lay at a small distance from the field of battle, found Sandoval was approaching their town, they came out to welcome him, and expressed their great joy at the victory he had gained.
The next day Sandoval informed the inhabitants that he was obliged to leave again for Tezcuco. They told him they were desirous of accompanying him there, to pay their respects to Malinche, and to present to him the two sons of their late cazique, who had died a few days previously of the smallpox. On his death-bed, they said, he expressed a wish to the chiefs of the country that his sons might be introduced to Cortes to be installed by him as caziques of Chalco. The dying man had likewise recommended them to subject themselves to the great monarch of the teules, as it had been prophesied by their forefathers that, at some period or other, there would arrive from the rising of the sun a people with beards, for whom the dominion of these countries was predestined, and there was not the least doubt that that prophecy was fulfilled in our persons.
Sandoval returned to Tezcuco, taking along with him the two princes, several distinguished personages of Chalco and the eight Mexican prisoners. Cortes was highly delighted on seeing him again, and after Sandoval had related all that had taken place, he retired to his own quarters to receive the caziques of Chalco. He paid them every respect, and, according to their request, acknowledged them as vassals of our emperor, and then installed the two sons of the late cazique into their government. After the caziques had fulfilled their commission, they handed over their presents, which may have been worth about 200 pesos.
With the assistance of Doña Marina and Aguilar, Cortes had perfectly comprehended what these caziques had said. He showed them every possible kindness, and gave the government of Chalco to the elder prince, with several towns which were subject to it, and to the younger the township of Tlalmanalco, Chimalhuacan, Ayotzinco, and of other small towns, so that the elder came in for a little more than half of his father's dominions.
After Cortes had instilled many useful things into the hearts of these men and the young caziques, he dismissed them; and they offered, in return, to render us every service that lay in their power, assuring him, at the same time, that they had been peaceably inclined from the beginning, and that they had been prevented sooner taking the oath of allegiance to our emperor from fear of the Mexican garrison. They likewise informed Cortes that, previous to our retreat from Mexico, they had concealed from the Mexicans two Spaniards who had been sent by him to demand of them tribute in maise, and had conveyed them safely during night-time to our friends of Huexotzinco, thereby saving their lives. This we knew to be perfectly true, for we had been duly informed of it by one of those two Spaniards who had escaped to Tlascalla.
