first thing Cortes required of him at present was a sufficient number of hands to assist us in launching the brigantines when they should be completed, and to lengthen and deepen the canals where they were to be launched; he then informed the king and chief personages of Tezcuco for what he intended these vessels, and of his determination to inclose Mexico on all sides. They not only declared their willingness to cooperate with us, but even sent messengers to the neighbouring townships, inviting them to seek our friendship, subject themselves to our emperor, and declare war against Mexico. The whole of our troops were now divided into companies, to each one was assigned some particular station, which, indeed, was very necessary, as Quauhtemoctzin sent out from time to time numbers of large pirogues and canoes, to see whether we were off our guard or not. About this time several tribes which were subject to Tezcuco came to sue for peace with us and beg forgiveness, if we thought they had been any way implicated in the late murders of our countrymen. Cortes received them most kindly, and took them into his friendship. The building of our brigantines was now rapidly continued, and there were every day from seven to eight thousand Indians employed to lengthen and deepen one of the canals. As we had an equal number of Tlascallans in our service, who greatly desired to heap up honour for themselves in assisting us against the Mexicans, Cortes easily persuaded them to accompany him in an expedition against Iztapalapan, through which town we had passed on our first march to Mexico. Cuitlahuatzin, the king of this township, had been raised to the throne of Mexico, after the death of Motecusuma, and the inhabitants had done us considerable damage, and were continually committing their depredations on the townships of Chalco, Tlalmanalco, Amaquemecan, and Chimalhuacan, because these had entered into alliance with us. We had now been twelve days in Tezcuco without having achieved any thing worthy of mention, and therefore determined to open the campaign against Iztapalapan. CHAPTER CXXXVIII. _How we marched against Iztapalapan; Cortes taking along with him Alvarado and Oli; while Sandoval was left behind to protect Tezcuco._ The expedition against Iztapalapan was principally undertaken to please the Tlascallans, so great was their desire to try their strength again with the Mexicans on the field of battle. Their patience was almost exhausted, and they longed to revenge the death of their countrymen who were slain in our disastrous flight from Mexico. To this was likewise added, that the Tezcucans could scarcely supply the necessary provisions for so great a body of men, and it was not our interest to be too burdensome to them.
