At this period a proclamation was issued, by which all the soldiers were ordered to bring in the Indian prisoners to be branded, and to pay for them the royal dues. I have already mentioned the treatment we formerly met with at Tepeaca on a similar occasion, but we were worse used now at Tezcuco if possible. In the first place a fifth was taken away for the king; then another fifth for Cortes; and, what was still worse, most of the good female slaves were abstracted during the night. We had been promised that all the slaves should be rated according to their value; but the officers of the crown valued them as they thought proper, and at a most exorbitant rate. In consequence of this, the poor soldiers for the future passed their slaves as servants, denying that they were prisoners of war, to avoid the heavy duty; and such as were in favour with Cortes, often got their slaves marked privately, paying him the composition. Many of the slaves who happened to fall to bad masters, or such as had a bad reputation, used to run away; but their owners always remained debtors for their estimated value in the royal books, so that many were more in debt on this account than all the value of their share in the prize gold could pay for. About this time likewise, a ship arrived at Villa Rica from Spain with arms and gunpowder, in which came Julian de Alderete, who was sent out as royal treasurer. In the same vessel came the elder Orduna, who brought out five daughters after the conquest, all of whom were honourably married. Fra Melgarejo de Urrea, also, a Franciscan friar, came in this vessel, bringing a number of papal bulls, to quiet our consciences from any guilt we might have incurred during our warfare: He made a fortune of these in a few months, and returned to Spain. Several other persons came by this vessel, among whom were, Antonio Caravajal, who still lives in Mexico, though now very old; Geronimo Ruyz de la Mora; one Briones who was hanged about four years afterwards for sedition at Guatimala; and Alonzo Diaz, who now resides in Valladolid. We learned by this ship, with infinite satisfaction, that the bishop of Burgos had been deprived of all power over the affairs of the West Indies, as his majesty had been much displeased with his conduct in regard to our expedition, after having received a true account of our eminent services.

Scarcely were we apprised of the success of the inhabitants of Chalco and their confederates, when a new urgent message arrived from Chalco for assistance against a fresh invasion of the Mexicans. The brigantines intended for securing the command of the lake were now ready to launch, and we were all anxious to commence the siege of Mexico, yet Cortes was sensible of the importance of Chalco to the success of our ultimate operations, and determined to march in person to its support. Leaving the command in Tezcuco to Sandoval, Cortes marched for Chalco on Friday the 5th of April 1521, at the head of 300 infantry, including twenty crossbow-men, and fifteen musketeers, with thirty cavalry, and a large body of the auxiliaries of Tezcuco and Tlascala, meaning to clear the district of Chalco and the environs of the lake from the Mexicans. In this expedition, our general was accompanied by the treasurer Alderete, Melgarejo the Franciscan friar, with the captains Alvarado de Oli, and Tapia, and I also was on this expedition. We halted during the first night at Tlalmanalco, and reached Chalco next day, when Cortes convened all the chiefs of that state, to whom he communicated his intention of proceeding very soon to attack Mexico, in which they engaged to give him all the assistance in their power. We continued our march next day to Chimalhuecan or Chimalacoan, a town in the province of Chalco, where above twenty thousand warriors had assembled to join us, belonging to our allies of Chalco, Guaxocingo, Tlascala, Tezcuco, and other places, being the largest body of our allies that I had hitherto seen together. These were attracted by the hope of plunder, and by a voracious appetite for human flesh, just as the vultures and other birds of prey follow our armies in Italy, in order to feast on dead bodies after a battle.

At this place we were informed that the Mexican forces, and their allies or subjects in that neighbourhood, were in the field to oppose us. Cortes therefore issued orders to the army to be always ready for action at a moments warning, and we proceeded on our march next morning early, after hearing mass, our route lying between two ridges of rocks, the summits of which were fortified and filled with large bodies of the enemy48, who endeavoured by outcries and reproaches to incite us to attack them. But we pursued our march to Guaztepeque or Huaxtepec, a large town on the southern declivity of the mountains, which we found abandoned. Beyond this place we came to a plain in which water was very scarce, on one side of which was a lofty rock having a fortress on the summit which was filled with troops, who saluted us on our approach with showers of arrows and stones, by which three of our soldiers were wounded at the first discharge. Cortes ordered us to halt, and sent a party of cavalry to reconnoitre the rock, who reported on their return that the side where we then were seemed the most accessible. We were then ordered to the attack, Corral preceding us with the colours, and Cortes remained on the plain with our cavalry to protect the rear. On ascending the mountain, the Indians threw down great fragments of rock, which rolled among us and rebounded over our heads in a most frightful manner, so that it was wonderful how any of us escaped. This was a most injudicious attack, and very unlike the usual prudence of our general. One soldier, named Martin Valenciano, though defended by a helmet, was killed at my side. As we continued to ascend, three more soldiers, Gaspar Sanches, one named Bravo, and Alonzo Rodriguez, were slain, and two others knocked down, most of the rest being wounded, yet we continued to ascend. I was then young and active, and followed close behind our ensign, taking advantage of any hollows in the rock for shelter. Corral was wounded in the head, having his face all covered with blood, and the colours he bore were all torn to rags. "Senor Diaz," said he to me, "let us remain under cover, for it is impossible to advance, and it is all I can do to keep my hold." On looking down, I noticed Pedro Barba the captain of our crossbows climbing up with two soldiers, and taking advantage as we had done of the concavities of the rock. I called to him not to advance, as it was impossible to climb much farther, and utterly out of our power to gain the summit. He replied in lofty terms, to keep silence and proceed; on which I exerted myself and got a good way higher, saying we should see what he would do. At this moment a shower of large fragments of rocks came tumbling down, by which one of the soldiers along with Barba was crushed to death, after which he did not stir a step higher. Corral now called out to those below, desiring them to report to the general that it was utterly impossible to advance, and that even retreat was infinitely dangerous. On learning this, and being informed that most of us were wounded and many killed, as he could not see us on account of the inequalities of the rock, Cortes recalled us by signal, and we came back in a very bloody and bruised condition, eight of our party having been slain. Three even of the cavalry were killed on the plain and seven wounded, by the masses of rock, which rebounded to a great distance after their descent from so great a height.

Numerous bodies of Mexicans were lying in wait for us, intending to have attacked us while engaged in the ascent, and now advanced towards us in the plain; but we soon drove them before us, on which they took shelter among some other rocky ridges. We pursued them through some narrow passes among the rocks, and found they had taken shelter in another very strong fortress, similar to that from which we had been repulsed. We desisted for the present, and returned to our former post in search of water, our men and horses having been unable to procure any during the whole of this day. We found some appearance of springs at the foot of the rock, but they had been drawn dry by the great numbers of the enemy, and nothing remained but mud. Being under the necessity of endeavouring to procure water, we returned again to the second fortress, which was about a league and a half from the first, where we found a small village with a grove of mulberry trees, in which we discovered a very scanty spring. The people above discharged their missile weapons on our approach, seeming to be much more numerous than in the former place, and they were so situated that no shot from us could reach them. For some way up the rock, there were evident paths, but it seemed to present insurmountable difficulties against any attack. Fortunately for us there was another rock which commanded that on which the enemy were posted, and within shot, to which all our fire-arms and crossbows were detached, and the rest of our infantry proceeded to climb up the garrisoned rock slowly and with infinite difficulty. The enemy might easily have destroyed us by rolling down fragments of rocks on our heads, but their attention was called off from their main defence by our missiles, though rather at too great distance to produce much effect; yet having killed several of the enemy, they lost heart and offered to submit. On this, Cortes ordered five of their chiefs to come down, and offered to pardon them for their hostile resistance, on condition that they should induce those in the other fortress to surrender, which they accordingly engaged for. Cortes then sent the captains Xaramillo and de Ircio, with the ensign Corral and a party of men, among whom I was, to ascend the rock which had surrendered, giving us orders not to touch a grain of maize. I considered this as full permission to do ourselves all the good in our power. We found this fortress to consist of an extensive plain on the summit of a perpendicular rock, the entrance to which did not exceed twice the size of the mouth of an oven. The whole plain was full of men, women, and children, but they had not a drop of water. Twenty of their warriors had been slain by our shot, and a great many wounded. All their property was packed up in bales, among which there was a considerable quantity of tribute, which had been collected on purpose to be sent to Mexico. I had brought four of my Indian servants along with me, whom I began to load, and four of the natives whom I engaged in my service; but Captain De Ircio ordered me to desist, or he would report me to the general, putting me in mind that Cortes had forbidden us to touch a grain of maize. I answered that I had distinctly heard the orders about the maize, and for that reason I took the bales. But he would not allow me to carry any thing away, and reported me on our return to Cortes, expecting I should receive a reprimand; Cortes, however, observed that he was sorry I had not got the plunder, as the dogs would laugh at us and keep their property, after all the evil they had done us. De Ircio then proposed to return; but Cortes said it was not now time. The chiefs now returned from the other fortress, having induced its garrison to submit; and we returned to Huaxtepec that we might procure water. Our whole force was lodged for the night in the buildings belonging to the noble garden which I formerly mentioned, and I certainly never saw one of such beauty and magnificence. Our general and others who walked over all its extent, declared that it was most admirably disposed, and equalled the most magnificent they had ever seen in Spain.
