When we received intelligence that Cortes had run out with the brigantines, we advanced along our causeway up to the bridge, but this time with greater precaution. Our cavalry was stationed in front of the causeway, while the remaining troops moved along in a close body up to the bridge, the crossbow-men and musketeers keeping up an incessant fire upon the enemy. In this way we renewed the attack each day, and repaired the gaps in the causeway, but three of our men had been killed.
In the meantime the enemy did Sandoval considerable damage from the tops of the houses which stood in the water, and he therefore resolved to attack those which he was best able to get at. Quauhtemoctzin then sent off a large body of troops to the assistance of the town, with commands to cut through the causeway in Sandoval's rear. Cortes observing a vast number of canoes going in the direction of Iztapalapan, instantly steered with the brigantines for the same place, and ordered Oli, with the whole of his division, to shape his course thither along the causeway. They found the Mexicans already hard at work in cutting through the causeway, and concluded from this that Sandoval was destroying the houses which stood in the water. They found him, as they had suspected, already in the heat of an engagement with the enemy, who, however, retired on the approach of the brigantines.
Cortes now ordered Sandoval to quit Iztapalapan with his troops, and to take up his position at Tepeaquilla, in front of the causeway, which leads from this place to Mexico. This Tepeaquilla is at present dedicated to our dear lady of Guadaloupe, where so many miracles have happened, and still daily take place.
_How Cortes assigns particular stations to the twelve brigantines, the thirteenth being considered unfit for service._
Cortes, our officers, and the whole of the troops were now convinced that it was impossible to fight our way to the city along the causeways, unless we were covered on each side by a couple of the brigantines. Our general therefore joined four of these to Alvarado's division, he himself retaining six others near his head-quarters, which he had taken up where Oli was stationed; the remaining two he sent to Sandoval, for the smallest brigantine was not considered of sufficient bulk to make head against the large canoes, and was taken out of the service altogether, and the men distributed among the crews of the other twelve.
