CONQUEST OF MEXICO AND NEW SPAIN. CHAPTER CXXXVII. _How the whole of us marched towards Tezcuco, and what happened to us on our way there._ When Cortes found himself so well provided again with muskets, powder, crossbows, and horses, and observed how impatient the whole of us, officers as well as soldiers, were to commence the siege of the great city of Mexico, he desired the caziques of Tlascalla to furnish him with 10,000 of their troops to join us in the campaign of Tezcuco, as this was one of the largest towns of New Spain, and next in importance to Mexico. The elder Xicotencatl (now called Don Lorenzo de Vargas) assured him that not only the 10,000, but many more troops were at his service, and that the brave cazique Chichimeclatecl, our particular friend, would himself march out at their head. Cortes returned him the most sincere thanks, and, after having reviewed the whole of his troops, whose exact number[1] I have forgotten, we commenced our march on the fourth day after Christmas of the year 1520. The first night we quartered in a township which was subject to Tezcuco, and were provided with everything we required. From this place we arrived on the Mexican territory, where, if possible, we observed still greater precaution, and always had four of the horse-patrol and an equal number of foot in advance to explore the defiles, as we had been informed on our march that a very formidable mountain pass had been blocked up by large trees which the enemy had felled when notice of our approach was received in Mexico and Tezcuco. During this day's march, however, we met with no kind of obstacle, and quartered ourselves for the night about twelve miles further on, at the foot of a mountain. Here we found it very cold, but kept a sharp look out. With break of day we continued our march further up the mountain, and speedily arrived where the mountain pass had been blocked up by felled trees, and a deep hollow had been made; but as we had great numbers of Tlascallans with us, we soon managed to clear away the trees, and to fill up the hole, so as to enable our cavalry to pass over, a company of crossbow-men and musketeers marching in advance. We now ascended the mountain for some time, and then descended a little, until we came to a spot whence we had a fine view of the lake of Mexico and its large towns standing in the midst of the water.
