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 enemy[9], 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.

[8] Clavigero, II. 147, says that Cortes endeavoured at this time, but in vain, to come to an amicable agreement with the court of Mexico.--E.

[9] In this expedition Cortes appears, by the information of Clavigero, II. 152, to have crossed the southern mountains of the Mexican vale, and to have reduced Huastepec, Jautepec, Quauhnahuac, and other towns belonging to the Tlahuicas, who were subject to the Mexican empire; thus judiciously using his endeavours to strengthen his own party and to weaken that of the Mexicans, before proceeding to assail the capital of that powerful empire.--E.

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.

We marched next day towards the city of Cuernabaca or Quauhnahuac. The Mexicans who occupied that place came out to fight us, but were soon defeated and pursued to Teputztlan or Tepatlan, which we took by storm, and made a considerable booty of Indian women and other spoils. Cortes summoned the chiefs of this place to come in and submit; and on their refusal, and on-purpose to impress the inhabitants of other places with terror, he ordered about the half of this town to be set on fire. At this time, the chiefs of a town called Yauhtepec came to Cortes and made their submission. Next day, we returned to Cuernabaca, which is a large town in a very strong situation, being defended by a deep ravine with a small rivulet, which precludes all access except by two bridges, which the inhabitants had broken down on our approach. Cortes was informed of a ford about half a league above the town which was practicable for the cavalry, to which he marched, by which the main strength of the enemy was drawn off to oppose him. We of the infantry searched for means to pass the ravine, and at length discovered a very dangerous pass by means of some trees which hung over from both sides, by the help of which about thirty of us and a considerable number of our Tlascalan allies got across. Three fell into the ravine, one of whom broke his leg. It was a most terrifying passage, and at one time I was quite blind with giddiness. Having got over and formed, we fell unexpectedly on the flank and rear of the enemy, and being now joined by a party of the cavalry, we soon drove the enemy from the field into the neighbouring woods and rocks. We found considerable property in the town, and we were here all lodged in the buildings of a large garden belonging to the cacique of the district. A deputation of twenty of the chiefs of the Tlahuican nation now waited on Cortes, offering to submit their whole country to his authority, and threw all the blame of their hostilities on the Mexicans.

The object of our next march was against Xochimilco, a large city on the fresh water lake of Chalco, in which most of the houses are built. As it was late before we left Quauhnahuac, and the weather was exceedingly sultry, our troops suffered excessively for want of water, which was not to be procured on our route. Many of our allies fainted, and one of them, and also one of our soldiers died of thirst. Seeing the distress of the army, Cortes ordered a halt in a pine forest, and sent forwards a party in search of relief. As I saw my friend De Oli about to set off, I took three of my Indian servants and followed the party, who endeavoured to persuade me to return; but I was resolute, and De Oli at length consented, telling me I should have to fight my way. At the distance of about half a league our cavalry came to some villages on the side of a ridge of mountains, where they found water in the houses, and one of my servants brought me a large jar full of water. Having quenched my thirst, I now determined to return, as the natives had taken the alarm, and were gathering to attack us. I found Cortes just about to resume the march, and gave him and the officers, who were with him a hearty draught from my jar. The whole army now moved forward to the villages, where a scanty supply of water was procured. It was now near sunset, and the cavalry came in with a report that the whole country had risen against us, on which account we halted here for the night, which was very rainy with much wind, as I well remember, being on the night guard. Several of our soldiers were taken ill here with inflammation of their mouth and throat, owing to their having eaten a species of artichoke to quench their thirst.

We resumed our march early next morning, and arrived about eight o'clock at Xochimilco[10]. I can give no idea of the prodigious force of the enemy which was collected at this place to oppose us. They had broken down the bridges, and fortified themselves with many parapets and pallisades, and many of their chiefs were armed with the swords which we lost during our flight from Mexico, which they had polished very nicely. The attack at the bridge lasted above half an hour, several of our people getting across by swimming, in which attempt some were drowned, and we were assailed at once in front and rear and on both flanks. At length our cavalry got on firm ground, after losing several men, and we drove the enemy before us; but just at this time a fresh reinforcement of at least 10,000 Mexicans arrived, and received the charge of the cavalry with great intrepidity, and wounded four of our men. At this moment the good chesnut horse on which Cortes rode fell under him among a crowd of the enemy, who knocked him down, and great numbers gathering around were carrying him off, when a body of our Tlascalan allies came up to his rescue, headed by the valiant De Oli, and remounted him, after he had been severely wounded in the head. De Oli also received three desperate sword wounds from the enemy. As all the streets of the town were full of Mexican warriors, we had to divide into a number of separate bodies in order to fight them; but we who were nearest the place in which our general was in such danger, being alarmed by the uncommon noise and outcry, hurried there, where they found him and about fifteen of the cavalry in a very embarrassing situation, amid parapets and canals where the horse had no freedom to act. We immediately attacked the enemy, whom we forced to give ground, and brought off Cortes and De Oli. On first passing at the bridge, Cortes had ordered the cavalry to act in two divisions on purpose to clear our flanks: They returned at this time all wounded, and reported that the enemy were so numerous and desperate, that all their efforts wore unavailing to drive them away. At the time the cavalry came in, we were in an enclosed court, dressing our wounds with rags and burnt oil; and the enemy sent in such showers of arrows among us that hardly any escaped being wounded. We all now sallied out upon the enemy, both cavalry and infantry, and made considerable havoc among them with our swords, so that we drove them away and they gave over their attempt to storm our post. Having now some relaxation, Cortes brought our whole force to the large enclosures in which the temples were situated; and on some of us ascending to the top of one of the temples, where we had a commanding view of Mexico and the lake, we perceived about two thousand canoes full of troops coming to attack us. A body of ten thousand men were likewise seen in full march by land for the same purpose, and the enemy had already fully that number in and about the town. We learned from five chiefs whom we had made prisoners, that this immense force was destined to assault our quarters that night; for which reason strong guards were posted at all the places where the enemy were expected to disembark; the cavalry were held in readiness to charge upon them on the roads and firm ground; and constant patroles were kept going about during the night. I was posted along with ten other soldiers to keep guard at a stone and lime wall which commanded one of the landing-places, and while there we heard a noise occasioned by the approach of a party of the enemy, whom we beat off, sending a report to Cortes by one of our number. The enemy made a second attempt, in which they knocked down two of our men; but being again repulsed, they made an attempt to land at a different place, where there was a small gate communicating with a deep canal. The night was extremely dark, and as the natives were not accustomed to fight in the night time, their troops fell into confusion; and instead of making their attack in two opposite places at the same time, they formed in one body of at least 15,000 men.

[10] This beautiful city was the largest in the vale of Mexico, after the capital and the royal residences of Tezcuco and Tlacopan, and was famous for its floating gardens, whence it derived its name, signifying flower gardens in the Mexican language.--Clavig. II. 155.

When our report reached Cortes, he came to us attended by nine or ten of the cavalry, and as he did not answer my challenge, I and my comrade Gonzalo Sanchez, a Portuguese from Algarve, fired three or four shots at them; on which knowing our voices, Cortes observed to his escort, that this post did not require to be inspected, as it was in charge of two of his veterans. He then observed that our post was a dangerous one, and continued his rounds without saying any more. I was afterwards told that one of the soldiers of Narvaez was whipped this very night for negligence on his post. As our powder was all expended, we were ordered to prepare a good supply of arrows for the crossbows, and were employed all the rest of the night in heading and feathering these, under the direction of Pedro Barba, who was captain of the crossbow-men. At break of day the enemy made a fresh attack and killed one Spaniard, but we drove them back, killing several of their chiefs, and took a great many prisoners. Our cavalry had been ordered out to charge the Mexicans, but finding them in great force, they sent back for assistance. The whole of our army now sallied forth and completely defeated the enemy, from whom we took several prisoners. From these men, we learned that the Mexicans intended to weary us out by reiterated attacks, on which account it was resolved to evacuate the place next day. In the mean time, having information that the town contained much wealth, we got some of the prisoners to point out the houses in which it was contained, which stood in the water of the fresh water lake, and could only be approached by small bridges over the canals, leading from a causeway. A considerable number both of our men and of the allies went to these houses, from which they brought away a great deal of booty in cotton cloth and other valuable articles, and this example was followed by others. While thus employed, a body of Mexicans came upon them unexpectedly in canoes, and besides wounding many of our men, they seized four soldiers alive, whom they carried off in triumph to Mexico; and from these men Guatimotzin learnt the smallness of our number, and the great loss we had sustained in killed and wounded. After questioning them as much as he thought proper, Guatimotzin commanded their hands and feet to be cut off, and sent them in this mutilated condition through many of the surrounding districts, as an example of the treatment he intended for us all, and then ordered them to be put to death.
