Thus taken by surprise, and driven, before they were ready, into an unequal conflict with enemies who had, by some miracle, as they supposed, anticipated their movements, and struck the first blow, the Cholulans rushed in from all parts of their city, hoping to retrieve, by their numbers and prowess, the disadvantage of the lost onset. Cortez had prepared for this. He had ordered his artillery to be stationed at the main entrances to the square, where they poured in a raking fire upon the assailants, rushing in from all the avenues. The surprise being so sudden, and the leaders having been shot down at the first charge, confusion and consternation prevailed among the discomfited Cholulans, who alternately fled, like affrighted sheep, from the scene of slaughter, and then rushed back, like exasperated wolves, to the work of death. In anticipation of this conflict, the Spanish general had concerted a signal with his Tlascalan allies, without the gates, who now came rushing in, like hungry tigers, revelling in the opportunity to inflict a terrible vengeance upon their ancient enemies. Falling upon their rear, as they crowded in from the remoter quarters of the city towards the field of carnage, they drove them in upon the weapons of the Spaniards, from which there was now no escape. Turning upon this new enemy, they fought with desperate bravery, to win a retreat. But they were cut down on this side and that, till the streets were scarcely passable for the heaps of the dead and dying that cumbered them. Those who took refuge in their houses and temples, found no safety in such retreats, for they were instantly fired by the Tlascalans, and their defenders perished miserably in the flames.
