At the time when Gonzalo Pizarro sent Bachicao with the brigantines to get possession of the ships belonging to the viceroy, he dispatched Gonzalo Diaz de Pinera and Jerom de Villegas to collect the soldiers who dwelt in Truxillo and San Miguel, that they might make head against the viceroy in the north of Peru. These officers remained in San Miguel with about eighty men whom they had drawn to their party, till they heard of the approach of the viceroy; on which, not being in sufficient force to oppose him, they retreated towards Truxillo, and established themselves in the province of _Collique_, about forty leagues[14] from San Miguel. From thence they sent intimation to Gonzalo of the advance of the viceroy, and that his army increased daily in numbers, insomuch that it behoved him to think of some appropriate measures to avert the threatened danger. Diaz and Villegas were likewise informed that the viceroy had sent Juan de Pereira, one of his officers, into the province of Chachapoyas, in which there were very few Spanish settlers, to endeavour to collect reinforcements. As they believed that Pereira and his followers entertained no suspicions of their being in the neighbourhood, Diaz and Villegas determined on attempting to surprize them, which they did so effectually one night, that they made the whole party prisoners without resistance. Having beheaded Pereira and two of his principal followers, they obliged the rest of the party, about sixty horsemen, to enter into the service of Gonzalo, by threats of putting them all to death if they refused; after which they returned to their post. [Footnote 14: The distance in the text is probably a mistake for _fourteen_ leagues, as about that distance to the S.E. of San Miguel there is a river named _Chola_, which may have given name to the district or valley in which it runs.--E.] The viceroy was greatly incensed by this untoward event, and determined to seek an opportunity of revenge. With this view he departed secretly from San Miguel with a body of an hundred and fifty horse, and took such judicious measures that he arrived one night undiscovered at _Collique,_ where he surprized the enemy, and obliged them to fly in all directions. Diaz made his escape almost alone into a district inhabited by hostile Indians, who assailed him and put him to death. Villegas and Ferdinand Alvarado were more fortunate in their escape, as they were able to collect some of their dispersed troops, with whom they took up a new and more secure position not far from Truxillo, and at a safer distance from San Miguel.
