spot where the pirogues lay in ambush. The greater exertions the canoes made to escape, the more eager were our brigantines in pursuit, and when these were close in upon the spot where the pirogues lay concealed, the latter suddenly darted forth from the reeds, and attacked the brigantines on all sides. In an instant all the officers, soldiers, and sailors were wounded, nor could the brigantines seek refuge in flight, as they had become entangled among the stakes. In this unfortunate affair we lost one of the brigantines and two of our officers, one of whom, named Portillo, a man of great courage, and who had served in Italy, was killed on the spot; the other was Pedro Barba, a very clever officer, who died of his wounds three days after. Both these brigantines belonged to Cortes' division, and he was sorely grieved at the loss we had thus sustained; but we very shortly after paid the enemy out in their own coin, as will presently be seen.
In the meantime Cortes and Sandoval, with their divisions, had many severe encounters with the enemy, but particularly Cortes, as he insisted that all the houses which were taken should be immediately pulled down, and the gaps in the causeway filled up. So that every inch of ground was rendered secure and level, of which possession was taken.
Alvarado had received similar instructions from our general, and was not to pass over any bridge or canal before the part which intersected the causeway was completely filled up; nor to advance beyond any house until it was levelled to the ground.
These commands were strictly adhered to, and with the woodwork and stones of the houses which we pulled down we filled up the openings in the causeways. In all these operations, and indeed during the whole of the siege, our Tlascallan friends lent us the most efficient services. When the Mexicans found we were thus by degrees pulling down their houses and filling up the canals, they determined to alter their plan of operation, and commenced by cutting a wide and deep opening in that part of the
