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.
