The warriors advanced to the sound of flutes. They shouted their war cries and beat their shields like drums. They pursued the Spaniards, harried and terrified them, and at last took fifteen of them prisoners. The rest of the Spaniards retreated to their ships and sailed out into the middle of the lake.
The prisoners were sacrificed in the place called Tlacochcalco [House of the Arsenal]. Their captors quickly plundered them, seizing their weapons, their cotton armor and everything else, until they stood naked. Then they were sacrificed to the god, while their comrades on the lake watched them being put to death.
Two of the barkentines sailed to Xocotitlan again. They anchored there, and the Spaniards began attacking the houses along the shore. But when Tzilacatzin and other warriors saw what was happening, they ran to the defense and drove the invaders into the water.
On another occasion, the barkentines approached Coyonacazco to attack the houses. As the ships closed in, a few Spaniards jumped out, ready for battle. They were led by Castaneda and by Xicotencatl, who was wearing his headdress of quetzal feathers.
Then Castaneda shot the catapult. It struck one of the Aztecs in the forehead and he fell dead where he was standing.The warriors charged the Spaniards, driving them into the water, and then loosed a hail of stones from their slings. Castaneda would have been killed in this action if a barkentine had not taken him aboard and sailed away toward Xocotitlan.
Another barkentine was anchored near the turn in the Wall, and still another near Teotlecco, where the road runs straight toTepetzinco. They were stationed as guards in order to control the lake. They sailed away that night, but after a few days they came back again to their stations.
The Spaniards advanced from the direction of Cuahuecatitlan. Their allies from Tlaxcala, Acolhuacan and Chalco filled up the canal so that the army could pass. They threw in adobe bricks and all the woodwork of the nearby houses: the lintels, the doorjambs, the beams and pillars. They even threw canestalks and rushes into the water.
