The caziques of Chalco, who were with Sandoval being aware that there was a much stronger body of Mexicans lying in Acapalista than had yet appeared in the field of battle, and that they merely awaited a favorable opportunity to renew the attack upon their town, urgently requested him to march thither, and drive the enemy out of that town. Sandoval at first refused to comply with their request, considering that he himself, with many of his troops, and most of the horses, were wounded, and that he did not wish to advance farther than Cortes had ordered him; besides which, several cavaliers of Narvaez's troops urged him to return to Tezcuco, and represented to him that Acapalista was a town of great strength, where they might easily meet with a total overthrow. But the captain Luis Marin strongly advised Sandoval to the contrary, and thought he was not justified in returning before the work was half finished, as the enemy would certainly renew the attack upon Chalco, and thereby defeat the object of the expedition altogether. By these arguments Sandoval was convinced of the necessity of marching against this town, which lay only eight miles farther on, and he set out for that place. When he had arrived in the neighbourhood of the town, a large body of Mexicans came advancing towards him, and attacked him so vigorously with their lances, slings, and arrows, that three horses and several of his men were instantly wounded, nor was Sandoval able to get at the enemy, who immediately retreated to the rocks and the fortified heights above, making a terrific noise with their drums, shell trumpets, and hideous yells. Sandoval now despatched a few horse in advance, to see whether the Mexicans, in case he should attack the town itself, could march to its assistance, and halted, with the rest of his troops, in the plain. As the caziques of Chalco and the other Indian allies showed no desire to come to an engagement with the enemy, Sandoval determined to put them to the proof, and cried out to them: "Well, why do you stand looking idly on there? Why don't you advance to the attack? Are we not come here to protect you?" But they replied, they durst not attack this strong place, and considered that the teules had come to do the hardest part of the work for them.
