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 direction where it was presumed they would be pursued by our brigantines.
