Amidst the din of battle, the voice of Cortés was heard, cheering on his soldiers. “If we fail now,” he cried, “the Cross of Christ can never be planted in the land. Forward, comrades! When was it ever known that a Castilian turned his back on a foe?”29 Animated by the words and heroic bearing of their general, the soldiers, with desperate efforts, at length succeeded in forcing a passage through the dark columns of the enemy, and emerged from the defile on the open plains beyond.
Here they quickly recovered their confidence with their superiority. The horse soon opened a space for the manœuvres of the artillery. The close files of their antagonists presented a sure mark; and the thunders of the ordnance vomiting forth torrents of fire and sulphurous smoke, the wide desolation caused in their ranks, and the strangely mangled carcasses of the slain, filled the barbarians with consternation and horror. They had no weapons to cope with these terrible engines, and their clumsy missiles, discharged from uncertain hands, seemed to fall ineffectual on the charmed heads of the Christians. What added to their embarrassment was the desire to carry off the dead and wounded from the field, a general practice among the people of Anahuac, but one which necessarily exposed them, while thus employed, to still greater loss.
Eight of their principal chiefs had now fallen, and Xicotencatl, finding himself wholly unable to make head against the Spaniards in the open field, ordered a retreat. Far from the confusion of a panic-struck mob, so common among barbarians, the Tlascalan force moved off the ground with all the order of a well-disciplined army. Cortés, as on the preceding day, was too well satisfied with his present advantage to desire to follow it up. It was within an hour of sunset, and he was anxious before nightfall to secure a good position, where he might refresh his wounded troops and bivouac for the night.30
