As soon as our brigantines espied the two canoes they went in pursuit of them, the latter keeping close into the reeds, and continually nearing the 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 causeway lying between us and the city; they deepened the lake on each side of this opening, and threw up entrenchments near it; strong stakes were then driven into the water to keep off our brigantines, or that they might run foul of them on coming to our assistance. Besides this, great numbers of canoes full of men were constantly lurking in places where we could not see them, with orders not to rush out upon us before we had advanced up to the entrenchments on the causeway.
One Sunday morning large bodies of the enemy came advancing towards us from three different points, and fell so fiercely upon us that it was with much difficulty we could maintain our ground. I had forgotten to mention that Alvarado had posted half of the cavalry on the causeway, for they no longer ran so great a risk of being killed, as most of the houses lay in ruins, and there was more space for them to manœuvre in, without their being exposed to the attacks of the enemy from the house-tops or from the lake. The enemy, as I have just said, advanced bravely from three different points, one body from the quarter where the deep gap had been made in the causeway, the other from the direction where the houses lay in ruins, the third from the side of Tlacupa, so that we were almost surrounded. Our cavalry, with the Tlascallans, had the good fortune to cut their way through the dense crowds which fell upon our rear, while our foot bravely opposed the two other bodies, which, after a few moments' desperate fighting began to give ground; but this was a mere stratagem of the Mexicans to allow us to take possession of the first entrenchment, and after a short stand they even retreated beyond the second. We thought we had already gained the victory, and waded through the shallow part of the water in vigorous pursuit of the enemy up to some large buildings and towers; while they, to deceive us the more effectually, constantly faced about to fling their arrows at us; and, when we in the least expected it, they suddenly turned round upon us and in an instant we were surrounded and attacked with excessive fury from all sides. It was impossible to resist their overwhelming numbers, and we began to retreat towards the causeway in the best order we could, with our ranks firmly closed. The first opening in the causeway which we had just taken from the enemy was already occupied by numerous canoes, so that we were compelled to make for the opening which the enemy had recently cut, where the water was very deep, and additional large holes had been dug. Here we had no other resource left than to make our way, either by swimming or wading through; but most of us got into the deep holes, when the canoes were instantly at hand to take advantage of our perilous situation.
On this occasion five of our men were made prisoners, and immediately taken into the presence of Quauhtemoctzin; and most of us were severely wounded. The brigantines certainly made every attempt to assist us, but were unable to come near enough, owing to the heavy stakes that had been driven into the water, between which they stuck fast, and were instantly assailed by showers of missiles from the house-tops and the numberless canoes, by which two of the rowers were killed, and the greater part of the troops on board wounded.
It was indeed a real wonder that all of us did not perish in these deep gaps. I myself was in extreme danger, for several Mexicans had already laid hands on me, but I succeeded in freeing one of my arms, and the Almighty gave me power to cut my way through the enemy, though I was severely wounded in the arm, and just as I had reached a place of safety I fell down breathless and exhausted. This sudden prostration of strength was no doubt owing to the extraordinary exertions I had made to disengage myself from the enemy's grasp, and to the quantity of blood I had lost. I gave myself up for lost when the Mexicans laid hold of me, and commended my soul to God and the holy Virgin.
Alvarado, with the cavalry, had hard work to keep off the numerous bodies who attacked our rear from the side towards Tlacupa, and had not advanced up to this fearful passage; there was only one cavalry soldier, recently arrived from Spain, who ventured too far, and perished with his horse. Alvarado was already coming up to our assistance, with a small body of horse, but fortunately not before we had made good our retreat beyond the deep gap; for, had he arrived a few minutes earlier, we should, no doubt, have faced about, fought our way back again into the town, and the Mexicans would certainly have cut us off to a man.
This battle took place on a Sunday, and the Mexicans were so elated with the victory they had gained over us, that they fell upon our camp with renewed courage, and in so large a body that they would certainly have taken it by storm but for our cannon and the desperate courage we displayed for the preservation of our lives. During this night, the whole of us remained under arms ready for action, and the horses stood ready saddled and bridled. Cortes was excessively grieved at the defeat we had sustained, and despatched a letter to Alvarado by one of the brigantines in which he told him not, under any circumstances, in future to pass beyond a gap or opening in the causeway before it had been quite filled up; and to keep the horses saddled all day and night, and to observe the utmost vigilance.
Our recent defeat having taught us prudence, we set about filling up the larger opening with the utmost expedition, and completed the work in four days; though it was a labour of great difficulty, and we were the whole time exposed to the attacks of the enemy, who killed six of our men and wounded several others. During the night, each company watched by turns to prevent the Mexicans from destroying our day's work.
As the Mexicans were encamped over against us, we could observe how they regulated their night watches: they were relieved four times during the night, and the men posted at such distances around a large fire, which was kept up till morning, that they could not be seen excepting at the moments when they poked the fire or when the next watch came to relieve. On some nights the fire became extinguished by the rain, but it was instantly relit; though everything was done in the utmost silence and not a word was exchanged, for they only communicated with each other by whistling. Many a time when we heard the guard approaching to relieve the watch, our crossbow-men and musketeers would shoot in among them at random, but without doing them the slightest injury, as they were posted in places which, even during broad daylight, were beyond the reach of our fire, particularly behind a deep ditch, which they had recently dug, and strengthened by a palisade and breastwork. The Mexicans never omitted to return the compliment, and let fly many an arrow at us in the same way.
The conflict on the causeway was daily renewed, and we always made our attacks in the best order possible, so that we soon became masters of the fosse just mentioned, behind which the enemy encamped at nights, but we had each time to encounter vast bodies of men, and the whole of us were more or
