When the governor had passed the river Paraná he was greatly disappointed at not finding the two brigantines which he had ordered by letter the two captains who were at the Ascension to send, these vessels being much needed to protect the passage for the transport of the sick and those who were fatigued with the long journey. As there were many incapable of marching who could not safely be left behind in the midst of so many enemies, who might soon pluck up courage to attempt some of their treasonable practices, he arranged to send the sick down the Paraná on the rafts, entrusting them to the care of an Indian chief named Yguaron, to whom he gave presents. This man offered to take charge of the sick in person and bring them to the village of Francisco, a servant of Gonzalo de Acosta, in the expectation that by the way they would meet the brigantines, and would be received and entertained by them; meanwhile this Indian, Francisco, who had been brought up among Christians and who lived on the bank of the Paraná, four days' journey from the point of their departure, according to the information of the natives, would look after them. So the governor ordered them to embark, and they were about thirty men, and he sent with them fifty arquebusiers and crossbowmen for their protection.
