Chalco and Tlalmanalco were two places of material importance to us at this time, as they lay in the direct road between Tlascala and our head-quarters at Tezcuco, but both of them were garrisoned by Mexican troops; and though Cortes was at this time solicited by several important districts to enable them to throw off the yoke of Mexico, he considered it as of the first necessity to dislodge the Mexicans from these two towns, on purpose to open a secure communication with our allies, and to cover the transport of our ship timber from Tlascala. He sent therefore a strong detachment of fifteen horse and two hundred infantry under Sandoval and De Lugo, with orders to drive the Mexicans from that part of the country, and to open a clear communication with Villa Rica. During the march, Sandoval placed ten of his men as a rear guard, to protect a considerable number of our allies who were returning home to Tlascala loaded with plunder. The Mexicans fell upon this weak rear-guard by surprise during the march, killing two of our men and wounding all the rest; and though Sandoval made all the haste he could to their rescue, the Mexicans escaped on board their canoes with very little loss. He now placed the Tlascalans in security, by escorting them beyond the Mexican garrisons, and sent forward the letter of our general to the commandant of Villa Rica, by which he was enjoined to send what reinforcements he could possibly spare to Tlascala, there to wait until they were quite certain that the road from thence to Tezcuco was clear. Sandoval, after seeing the Tlascalans safe upon their journey, returned towards Chalco, sending word secretly to the inhabitants, who were very impatient under the Mexican yoke, to be in readiness to join him. He was attacked on his march through a plain covered with maize and _maguey_, by a strong body of Mexican troops, who wounded several of his men; but they were soon repulsed and pursued to a considerable distance by the cavalry. Sandoval now prosecuted his march to Chalco, where he found the cacique of that place had recently died of the small-pox, having recommended his two sons on his deathbed to the protection of Cortes, as he was convinced we were the bearded men who, according to their ancient prophecy, were to come from the eastern countries to rule over this land, and had therefore commanded his sons to receive the investiture of their state from the hands of Cortes. Sandoval set out therefore for Tezcuco next day, talking along with him the two young lords of Chalco, and many of the nobles of that place, carrying a present of golden ornaments to our general worth about 200,000 crowns. Cortes accordingly received the young princes of Chalco with great distinction, and divided their fathers territories between them; giving the city of Chalco and the largest share of the district to the elder brother, and Tlalmanalco, Aytocinco, and Chimalhuacan to the younger.
