Our captain, Luis Marin, thought proper to wait upon Cortes, to represent the necessity of a reinforcement; and accordingly got thirty soldiers, commanded by Alonzo de Grado, with orders for all the Spaniards at Coatzacualco to march for the province of Chiapa, which was then in a state of rebellion, and directions to build a town there to keep the natives in order. In the first place, we had to make roads through the woods, and the country being very marshy, we were under the necessity of constructing causeways in many places to enable the horses to pass. The first place we came to was Tezputzlan, and thence to Cachula, beyond which there had been no passage before our expedition, all the other natives being in great fear of the inhabitants of Chiapa, who were then the bravest warriors in all America, and had never been subdued by the Mexicans; but they were extremely barbarous, being in use to rob all passengers, and to carry away the natives of other districts to till their ground. The present expedition was during Lent, and as well as I can now remember, in the year 1524, our little army consisting of 27 cavalry, 23 musqueteers, 72 foot soldiers armed with sword and target, and one field-piece under the direction of a cowardly fellow of a gunner, who pretended to have served in Italy. Besides these, we had 50 Mexican warriors, and the cacique of Cachula with some of his principal people, who were all terribly afraid. On approaching Chiapa, an advanced guard of four of our most active soldiers, of whom I was one, always preceded the army to reconnoitre, and as the ground was not fit for a horse, I left mine behind. We were usually about half a league in front of the army, but on our approach to Estapa, their first settlement, some of the hunters of Chiapa perceived us at a distance, and gave the alarm by means of smoke. The road was now wide and convenient, between well cultivated fields of corn and other vegetables; and on coming to Estapa we found it abandoned by the inhabitants, on which we posted our guards and patroles, and took up our quarters for the night. We were soon disturbed by information from our out-guards, that the natives were collecting on every side to attack us; and, going out of town to meet them we had a severe action, in which they killed two of our soldiers and four horses, wounding our reverend father Fra Juan, and thirteen soldiers, including our captain Luis Marin, who was wounded in two places; besides which many of our allies were slain. This action lasted till dark night, when the enemy were forced to retire, leaving fifteen slain and many wounded in the field. From two of the wounded, who seemed chiefs, we learnt that a general attack was intended against us next day. These people were clothed in good defensive armour of quilted cotton, using darts hardened in the fire, war clubs, and lances longer than ours, and they fought with unusual bravery; insomuch that, when one of our horsemen halted to make a thrust, the Indians seized the horse, and either wrested the lance from the horseman or pulled him to the ground.

Next day we pursued our march to Chiapa, a place with very regular streets, and containing not less than four thousand families, besides the dependent towns and villages around. We had not proceeded above a quarter of a league from Estapa, where we had passed the night, when we found the whole warriors of the district drawn up to oppose us, well armed, dressed up in plumes of feathers, and making the hills resound with their warlike shouts. They attacked us with the utmost fury, and our black gunner was so stupified with fear, that he stood long trembling before he durst put the match to the gun, and when he fired the piece all the good he did was wounding three of our own men. After a severe conflict, we at length forced them to fly; but they rallied in some broken ground, reinforced by some fresh bodies of Indians, and attacked us again by surprize, while we were giving God thanks for our victory. In these new troops, many were provided with long thongs to twist round our horses, and some carried the nets they used in hunting for the same purpose. In this second battle the enemy were so desperate that they killed two of our soldiers and five horses, and scarce one of us escaped without a wound. They had along with them a very fat aged woman, whom they esteemed a wizard, who had promised them the victory. Her body was all covered over with paint mixed with cotton wool; and she advanced fearlessly amid our allies, who were regularly formed by companies, by whom she was cut to pieces. At length, by a violent effort, we forced the enemy to fly, some taking to the rocks and others to the river, and being excellent swimmers they made their escape. We then halted and sang the Salve regina: After which we took possession of a town on the river, where we halted for the night, taking care of our wounded, and carefully concealing our dead.

About midnight, ten chiefs of neighbouring districts came down the river in five canoes, and were brought to our captain, whom they informed that they belonged to the nation of the Xaltepecs, who were at war with the people of Chiapa, and came to offer their assistance to us against them, on condition that we should afterwards support the independence of their nation against the people of Chiapa. This was very satisfactory to us, as we could not have passed the river, which was both broad and deep, without their assistance; the chiefs were therefore dismissed with a promise on our part of protection, and on theirs to bring us canoes and auxiliaries. During the remainder of the night we had to keep strict guard, as the drums and horns of the enemy were heard on the opposite banks of the river, where their warriors were collecting from all sides to attack us. As soon as it was light, our new friends joined us with the promised canoes, and shewed us a very dangerous ford, which they urged us to pass without delay, that we might endeavour to save the lives of some of their people who had been recently made prisoners by the enemy. We accordingly passed the river in a solid column at the ford, which reached our armpits, and where we lost one of our cavalry. On gaining the opposite bank, we were so hotly assailed by the enemy with darts and arrows, that every one of us had two or three wounds before we got out of the water. But as we were now joined by large bodies of those Indians who had offered their assistance, we soon compelled the enemy to fly for shelter to their city, against which we immediately advanced in good order, accompanied by our new allies. On arriving there, it seemed too closely built to be occupied with safety, and we encamped therefore in the open field, sending messengers to invite them to peace, with which they complied, by sending a deputation of their chiefs, who submitted to become subject to our sovereign, and requiring that the neighbouring tribes might be prevented from destroying their houses and plantations. All these things being settled to our mutual satisfaction, we went into the town, where we found many prisoners confined in wooden cages, who had been seized by the Chiapese while travelling from place to place, all of whom we set free. In the temples of this place we found several idols of horrible figures, and many remains of men and boys, who had been recently sacrificed. Our reverend father Fra Juan, broke all the idols to pieces, and preached so successfully that many were baptized. Many of the chiefs of the neighbouring tribes came in and made their submission: Among these were the chiefs of Cinacatan, Papanahaustla, Pinola, Guehuistlan, Chamula, the Quilenes, and others who spoke the Zoque language, and many other tribes, the names of which I do not now remember. These people were much surprised when they perceived the smallness of the force with which we had ventured to attack a nation so warlike as the Chiapese, whom the Mexicans were never able to subdue.
