Cortes gave him full power to share the command between himself and Cuenca, but it would have been much better if he had never given him this authority, as will presently be seen. However, Medina went down the river and found Cuenca lying at anchor with his vessels in front of Xicalango, awaiting Cortes' further commands, according to the instructions he had received. As soon as Medina stepped on board he produced his authority from our general with respect to the command, which gave rise to high words between both parties, and ended in so bloody a conflict in which the crews mingled, that they slew each other without mercy, and only seven men remained alive. But here misfortunes were not at an end, for when the Indians of Xicalango and Gueyatasta saw how the Spaniards quarrelled among themselves and weakened their strength, they fell suddenly upon those that survived, put them to death and then set fire to the vessels. Though we did not hear of all this until two years and a half had elapsed. The caziques of Ciguatepec informed us that we were still three days' journey from Gueyacala, and that we should have to cross two rivers, of which one was uncommonly deep and broad; after this our route would lay through an extensive moorland, full of dangerous bogs, and they assured us we should not be able to cross the rivers without canoes. Cortes therefore despatched two Spaniards with three distinguished Indians in advance, to bring him an accurate account of the state of the rivers and the marshes, and inform him what would be the easiest method of crossing them. The two soldiers who received these commands were, Pedro de Ribera and Martin Garcia, of Valencia, who was alguacil of our army, and in whom our general placed the greatest confidence. They set out on their march, explored the rivers in small canoes, and were of opinion that the only way to pass the former would be by throwing bridges across; but as for the marshes, which lay four miles further on, they had never even given them a thought, and they only brought word about the difficulty of throwing bridges across the water. Cortes then sent for myself and Gonsalo Mexia, and commissioned us to go in company of some of the chiefs of Ciguatepec to the Acallan townships, and do all in our power to gain the friendship of the inhabitants, that they might not run away as our army approached.
