It was not long before large bodies of Mexican troops arrived for the protection of Iztapalapan, with whom Sandoval had a severe skirmish, and drove them back again to their canoes; but still they continued to shower their arrows and darts upon him, and wounded several of his men.
During this conflict a thick smoke was seen to rise from several signal fires which had been lighted on the surrounding hills. This had been a signal to call in all the canoes of Mexico and of the other towns situated on the lake, as Cortes had just run out from Tezcuco with the thirteen brigantines.
The first attack our general made with this fleet was against a rocky height on an island near Mexico. This place had been strongly fortified, and was garrisoned by a great number of Mexicans and inhabitants of other townships. All the canoes of Mexico, Xochimilco, Cojohuacan, Huitzilopuzco, Iztapalapan, and Mexicalzinco, had united in a body to oppose Cortes, which was the reason why the attack was carried on with so little vigour against Sandoval, who, however, was not able to do the enemy much damage, as most of the houses stood in the water; though, in the commencement of the attack, our allies had made many prisoners. In Iztapalapan, Saudoval found himself on a peninsula in the lake, and the only way by which he could reach Cojohuacan was by a causeway which ran half way through the lake, on which he would have been assailed from both sides by the enemy, without his being able to defend himself with much advantage.
When Cortes observed the vast number of canoes which kept continually crowding around the brigantines, he began to feel alarmed, and this not without reason, for their number amounted to above 4000. He therefore abandoned his attack upon the rock, and selected a position with his brigantines, where he would be able to observe all the enemy's movements, and steer off in any direction he might choose. He likewise issued orders to the respective commanders of the brigantines not to commence an attack on the canoes before the wind, which had just commenced blowing from the land, should have increased. When the Mexicans found our fleet was moving off again, they not incorrectly ascribed it to fear, and they immediately advanced with their canoes to fall upon the brigantines. There now suddenly arose a stiffish breeze, our rowers pulled with all their might, and Cortes ordered the brigantines to run right in among the canoes. Numbers were bored into the ground, many of the enemy killed and wounded, and all the rest of the canoes turned round, and made off at a rapid rate, to seek refuge between the houses built in the lake, where they could not be followed by the brigantines. This was our first naval engagement, and Cortes gained the victory, thanks be to the Almighty.
After this encounter he steered for Cojohuacan, where Oli had taken up his position. Here again he fell in with large bodies of the enemy, who lay in wait for him at a point of considerable danger, and attempted to carry off two of the brigantines. They attacked him at the same time from their canoes, and from the tops of the temples. Cortes now fired in upon them with the cannon, and killed great numbers. The artillerymen fired away so incessantly upon this occasion, that all their powder was consumed, and some of them had their faces and hands burnt. Cortes then despatched the smallest brigantine to Iztapalapan, to bring away all the powder Sandoval had with him there, and wrote word to him not on any account to quit that place. He himself staid the two next days with Oli, on whose position the enemy continued their attacks without intermission.
I must now also relate what took place at this time in Tlacupa, where I was stationed with Alvarado.
When we received intelligence that Cortes had run out with the brigantines, we advanced along our causeway up to the bridge, but this time with greater precaution. Our cavalry was stationed in front of the causeway, while the remaining troops moved along in a close body up to the bridge, the crossbow-men and musketeers keeping up an incessant fire upon the enemy. In this way we renewed the attack each day, and repaired the gaps in the causeway, but three of our men had been killed.
In the meantime the enemy did Sandoval considerable damage from the tops of the houses which stood in the water, and he therefore resolved to attack those which he was best able to get at. Quauhtemoctzin then sent off a large body of troops to the assistance of the town, with commands to cut through the causeway in Sandoval's rear. Cortes observing a vast number of canoes going in the direction of Iztapalapan, instantly steered with the brigantines for the same place, and ordered Oli, with the whole of his division, to shape his course thither along the causeway. They found the Mexicans already hard at work in cutting through the causeway, and concluded from this that Sandoval was destroying the houses which stood in the water. They found him, as they had suspected, already in the heat of an engagement with the enemy, who, however, retired on the approach of the brigantines.
Cortes now ordered Sandoval to quit Iztapalapan with his troops, and to take up his position at Tepeaquilla, in front of the causeway, which leads from this place to Mexico. This Tepeaquilla is at present dedicated to our dear lady of Guadaloupe, where so many miracles have happened, and still daily take place.
