Mexican fleet now sallied out upon them, and our brigantine rowed away towards the place where the six others were concealed, closely followed up by the enemy. When arrived near enough, the brigantine fired two shots as a signal, on which the other vessels pushed out against the enemy, running down many of their vessels, dispersing all the rest, and making a great number of prisoners. This sickened them at ambushments, and from henceforwards they did not attempt to cross the lake in their canoes so openly. Our three divisions of the land army continued to pursue their plan for gradually advancing along the causeways. Always as we gained ground, we pulled down the houses on each side, filling up the ditches or canals which intersected the causeways, and strengthening our posts; in which, and in all the operations of the war, we were excellently seconded by our brave Tlascalan allies. On our attack, the Mexicans broke down one of the bridges in the rear of their own barricades and parapets, leaving one narrow passage at a place where the water was very deep as a decoy, and even dug trenches and pitfalls where the water was more shallow, placing pallisades in the deep water to prevent the approach of our vessels, and constructing parapets on both sides of the breach. They had also a number of canoes in readiness to sally out upon us on a concerted signal. When all these preparations were in readiness, they made a combined attack upon us in three several directions. One body advanced towards our rear from the side of Tacuba, a second directly on our front along the causeway from the city, and the third by the ruins of the houses which we had destroyed. We repulsed the enemy on all sides; and one party of us, having forced them from the works at the broken bridge, crossed the water up to our necks at the place they had left open for us, and rashly pushed on to an open place where there were some large temples and towers. We were here assailed on all sides by fresh troops from the houses and terraces, and those whom we pursued faced about and fought us in front. We now found it necessary to retreat, which we did with the utmost order till we came to the pass at the broken bridge, which was occupied by the enemy in canoes; and as the others pressed upon our rear, we were forced to throw ourselves into the lake and to get over any way we could. Those who could not swim got entangled among the concealed ditches and pits in the shallow water, where the enemy closed in upon us, wounding the whole party, and even taking five of our soldiers alive. The vessels which came to our relief were unable to approach, on account of the pallisades, and they lost two of their soldiers on this occasion. It was wonderful we were not all destroyed at this dangerous pass. At one time I was laid hold of by a number of the enemy; but God gave me strength to disengage my arm, and with the assistance of my good sword, I extricated myself from their grasp.
