In this way the battle continued for upwards of an hour, the enemy each time returning to the attack with such excessive fury that, at length, we could stand our ground no longer: nor was this all, for we now saw another large fleet of canoes approaching with a fresh body of men, who were ordered to fall upon our rear. We therefore determined to retreat back along the causeway, for which purpose we ordered the Tlascallans to move off first, that we might effect our retreat in perfect good order. Here the Tlascallans had greatly embarrassed us in our movements, who, it is well known, never can fight standing in the water. The instant the Mexicans perceived we were turning back, and saw the Tlascallans moving off the causeway, they set up most distracting yells, and attacked us man to man with great fierceness. It is indeed out of my power to describe it. The whole of the causeway was instantly covered with lances, arrows, and stones, besides that vast quantities fell into the water. When we had again reached the mainland, we returned fervent thanks to the Almighty for having rescued us from this severe battle. Eight of our men were killed and fifty wounded: added to all this, we were obliged to put up with the hootings and jeers of the enemy, who kept calling upon the Tlascallans to come with double their numbers next time, and they would very soon settle their impudence. Our first deeds of arms, therefore, merely consisted in destroying the aqueduct of Chapultepec, and in reconnoitring the lake along the causeway, in which we did not exactly reap much honour. For the rest, we passed the following night very quietly in our quarters, posted our sentinels, and dressed our wounds. One of our horses was so severely wounded that it died soon after. The following morning Oli determined upon taking up the position assigned to his division at Cojohuacan, about six miles further on; and however Alvarado and the other cavaliers might beg of him not to separate the two divisions, yet he would not alter his determination. Christobal de Oli was a man of uncommon bravery, whose pride was wounded at the unsuccessful attempt we had made upon the causeway, and he accused Alvarado of inconsiderateness for having ordered the attack. Nothing, therefore, could induce him to stay, and he marched off with his men to Cojohuacan. The separation of the two divisions was very impolitic at this juncture; for if the Mexicans had been aware of the smallness of our numbers, and had attacked either of the divisions during the five following days, before the brigantines had arrived, we should with difficulty have escaped destruction. Both divisions, therefore, remained as quiet as the enemy would allow them, though not a day passed by that the Mexicans did not land troops to annoy us in our camp, and, if possible, to entice us into places where we should be unable to act, and they could attack us to greater advantage.
