I have before mentioned of what little use the cavalry was to us in our operations on the causeway; for whenever they did drive the Mexicans before them up to the bridges, the latter leaped into the water, and retreated behind the entrenchments which they had thrown up on the causeway itself, where other bodies of the enemy stood ready to receive them armed with extremely long lances, with which, and various kinds of projectiles, they severely wounded our horses; so that the owners of the horses were very unwilling to risk them in such unequal conflict; for at that time the ordinary price of a horse was from 800 to 1000 pesos.
When night came on, and released us from the attacks of the enemy, we returned to our encampment, and attended to our wounds, which we dressed with bandages steeped in oil. There was likewise a soldier among our troops, named Juan Catalan, who charmed the wounds, and the Lord Jesus blessed this man's exertions in a manner that he invariably succeeded in his cures. Indeed, if all our wounded, each day we renewed the attack, had remained behind in our camp, none of the companies could ever have sallied out with more than twenty men at a time. When our friends of Tlascalla observed how this man charmed the wounds, and how every one who was wounded applied to him for assistance, they likewise brought him all their wounded, and these were so very numerous, that his only occupation throughout the day consisted in charming wounds.
Our officers and ensigns were most exposed to the enemy's weapons, and were oftener wounded in consequence; for which reason a fresh set of men were each day appointed to carry our tattered colours. With all these hardships we had to suffer, it will at least be thought that we had plenty of food. But of this we were likewise deprived, and we should have thought ourselves fortunate if we had only had some refreshing food for our wounded; we had not even a cake of maise! Miserable indeed was our distress! The only means we had of keeping soul and body together was by eating herbs and cherries, and at last we had nothing to subsist on but wild figs; Cortes and Sandoval's divisions fared no better than ours, and the Mexicans likewise continued the attack upon them from morning to night. Every blessed day that came they were obliged to advance fighting their way up to the bridges along the causeway; for the Mexicans, and the troops which lay in the other towns of the lake, merely awaited the morning dawn, when the signals were given from the summit of the great temple of Huitzilopochtli to rush out upon us both by land and water.
The operations of the besieged were carried on with perfect order, and it was previously settled where the different bodies of their troops were to direct the attack.
As we began to experience that our daily advancing along the causeway each time cost us a loss of men, besides that we gained little advantage by it, for the Mexicans returned in the night, and again took possession of the points we had forced, we determined to alter our plan of operations, and took up a position on a more spacious part of the causeway, where several towers rose up together, and where we should be able to quarter ourselves for the night. Though we were miserably off here, and had nothing to protect us from the rain, nor to cover us from the piercing rays of the sun, we were not to be deterred from our purpose. The Indian females who baked our bread were obliged to remain behind in Tlacupa, protected by our cavalry, and the Tlascallans, who at the same time covered our rear, that the enemy might not fall upon us from the mainland. After these precautions had been adopted, we began to carry out our principal object, which was to make ourselves master of the houses in the suburbs, and of the intervening canals. These last were then immediately filled up, and the houses pulled down; for, as I have before mentioned, it was difficult to destroy them by fire, as they were detached, and stood in the water. It was from the tops of the houses that we received most injury from the enemy; so that, by destroying these, we gained a considerable advantage. Whenever we had taken one of the enemy's entrenchments, a bridge, or forced any other strong position, we were obliged to occupy the spot night and day with our troops, which we regulated in the following manner: – Each company watched by turns; the first from the evening time until midnight; the second from midnight until a couple of hours before daylight; and the third from that time till morning, when they were relieved by forty other men. The watch was each time relieved by a like number, though none of these watches left the spot; but when the following arrived, the former lay themselves on the bare ground, and took a little repose; so that when daylight came there were always one hundred and twenty men collected together ready for action. On other nights, when we expected some sudden attack, the whole of the men marched up at once, and remained under arms until the enemy approached. We had every reason to be upon our guard, for we learnt from several Mexican officers, whom we had taken prisoners in the different engagements, that Quauhtemoctzin and his generals had come to the determination of falling some day or night suddenly upon our encampment on the causeway; and concluded that, after they had destroyed us, they might easily make themselves masters of the two other causeways occupied by Sandoval and Cortes. To accomplish this finishing stroke, the nine towns lying in the lake, besides Tlacupa, Escapuzalco, and Tenayucan, were to cooperate with them. While we should thus be attacked on every side, they meant to carry off the Indian females with our baggage, which we had left behind in Tlacupa.
As soon as we received this information, we sent notice of it to the Tlascallans and our cavalry, who were stationed at Tlacupa, and ordered them to be particularly upon their guard, and to keep a sharp look out all day and night. Nor was it long before the enemy put their scheme into operation; for one midnight an immense body of Mexicans came storming up against us; a couple of hours after another such a body; and with daylight a third came pouring forth. At one time they moved up with the utmost silence; at another they came fiercely along with hideous yells; and it was terrible to behold the innumerable quantities of lances, stones, and arrows they showered upon us. Though they wounded many of our men, we valiantly maintained our ground, and drove them back with great loss. The Mexicans had at the same time attacked the cavalry and Tlascallans on the mainland at Tlacupa; the latter suffered severely, as they were never much upon their guard during night-time.
In this way, amidst rain, wind, frost, up to our ancles in mud, and covered with wounds, we patiently bore our fatigues, with a morsel of maise cake, a few herbs and figs to stay our hunger, which was the more gnawing from the incessant exertions of our bodily strength. Yet, however bravely we might fight, we advanced but slowly, and the little advantages we gained cost us a number of killed and wounded. The bridges we forced were as often retaken by the enemy, and if we filled up an opening in the causeway new gaps were made, and this continued day after day, until the Mexicans altered their plan of operations, as will shortly be seen.
After thus enumerating these continued scenes of bloodshed and slaughter which took place at our station, and those of Cortes and Sandoval, the reader will ask, what advantage we had derived in destroying the aqueduct of Chapultepec? I must confess, very little; for the enemy received, during the night-time, a plentiful supply of water as well as of provisions from the towns surrounding Mexico, by means of their light canoes.
In order to cut off these supplies, Cortes determined that two brigantines should cruise about the lake during the whole of the night to capture these canoes, and it was agreed that the provisions found in them should be equally distributed among the three divisions. Although we sensibly felt the absence of our brigantines during the attacks which the enemy made upon us in the night-time, yet we soon began to find what great advantage we had gained by thus diminishing the enemy's supplies. No day passed without our brigantines capturing several of these transports laden with maise, fowls, and other necessaries of life, though a few always managed to elude our vessels and slip into the town. The Mexicans, therefore, were determined if possible to rid themselves of these troublesome brigantines, and thought of the following stratagem: They fitted out thirty large pirogues, manned with their best rowers and most courageous warriors, which they ran out during the night-time and concealed them among the reeds of the lake, where they could not be seen by the brigantines. At a short distance from the place where the pirogues lay concealed, stakes had been driven into the water, of which it was intended our two vessels should run foul. In the twilight the enemy sent out two or three canoes which were covered with green boughs, as if laden with provisions for Mexico; and these received instructions to move off in a
