When the news of the unfortunate termination of the battle reached Mexico, additional troops were immediately ordered to Tlacupa to oppose Cortes, and received instructions first to attack the Spaniards, and then to fall back upon Mexico, in order to entice the Spaniards to pursue them along the causeway. This stratagem succeeded admirably, for Cortes was deceived by their apparent flight, and pursued the enemy as far as a bridge, thinking the victory was already his. When the Mexicans considered they had caught the Spaniards sufficiently deep in the foil, they turned suddenly round, and fell upon them with such terrific numbers, by land, from their canoes, and from the house-tops, that Cortes almost gave himself up for lost. In his hurried flight over the bridge he was attacked by so vast a body, that all opposition was fruitless. One of our ensigns, determined not to relinquish his hold of the colours, was dangerously wounded in the struggle, and at last tumbled headlong with them into the water, but was fortunate enough to escape drowning, and, by dint of great bravery, succeeded to rescue himself and his flag, just when the Mexicans laid hold of him, and were about to drag him out of the water into a canoe.
In this unfortunate engagement we had five men killed and many wounded, and it was with the greatest difficulty our men could fight their way through the dense body of the enemy, and regain the main land.
After this battle Cortes stayed five more days in Tlacupa, during which time he had another engagement with the Mexicans and their allies; after which he began his march back to Tezcuco by the same road he had come. The Mexicans, who construed this movement into a flight, and imagined that Cortes had lost all courage, thought this was the moment to gain great honour to themselves, by giving the Spaniards a signal defeat. For this purpose they lay in wait for them in a spot where they could get easily at our horse; but met with so rough a reception from our troops, that a considerable number of them were slain. Cortes lost one man and two horses; but had so far cooled the enemy's lust for battle, that they no longer harassed him on his march, and in a few days he reached the township of Aculman, about eight miles and a half from Tezcuco, to which it was subject. When we were informed of his arrival there, Sandoval, with all of us, accompanied by nearly the whole of the caziques and troops of Tezcuco, went out to meet him. The joy at seeing each other again was very great, for we had been without any tidings of Cortes or his troops for fifteen days.
