On learning the success of Centeno at Cuzco and the death of De Robles, and being likewise informed that the people of San Miguel had declared for his majesty, and that the captains Mercadillo and Porcel had joined Diego de Mora at Caxamarca; Gonzalo Pizarro saw that he had now only to depend on the force which was along with himself at Lima, and those under Pedro de Puelles, on whose fidelity he reposed entire confidence. In this predicament, he determined to alter the destination of Juan d'Acosta and to send him against Centeno with a respectable force, resolving to follow d'Acosta in person with all his army if necessary, then amounting to nine hundred men, among whom were many of the principal inhabitants of Peru. In forming this new resolution, his object was in the first place to reduce all the upper or mountainous provinces to subjection, and afterwards to make war on every other part of the country which had withdrawn from his authority. It has likewise been conjectured, that Gonzalo proposed to himself, in case of any reverse, to endeavour to make some new discovery and conquest, towards the Rio Plata, or Chili, or in some other place to the south and east of Peru. He certainly never avowed this intention openly, nor is it alleged that he communicated it to any of his confidents, as this would have indicated a want of confidence in his cause; so that this idea rests only on conjecture. In consequence of this new plan, Gonzalo recalled D'Acosta to Lima with all his troops, to the great mortification of that person and his followers; insomuch that seven or eight of them deserted, choosing Jerome de Soria as their commander. Many others would certainly have followed this example, if it had not been for the severe precautions exercised by D'Acosta on the occasion, who put to death Lorenza Mexia, son-in-law to the Conde de Gomera, and another soldier, whom he suspected of intending to desert. He likewise arrested several others who were suspected of similar intentions, whom he carried prisoners to Lima.
