The president, having completed his preparations, began his march from Jauja in good order on the 19th of December 1547, taking the route of Cuzco, and especially desirous of crossing the river Abancay[34] in some safe place. In this part of his march he was joined by Pedro de Valdivia, the governor of Chili. Valdivia had come by sea to Lima, on purpose to raise men, and to procure various stores of which he was in want, with clothing and ammunition, on purpose to enable him to proceed in the conquest of Chili. On his arrival at Lima, and learning the situation of affairs in Peru, he determined upon joining the president. His arrival was considered as an indication of good fortune; for, although the president had already in his army many officers of merit and capacity, and of eminent rank and fortune, there was not any one in Peru who possessed so much experience in the manner of conducting warlike operations in that country as Valdivia, on which account he was considered as a fit person to be opposed to the experience and stratagems of Carvajal, who was much dreaded by every one in the presidents army, more especially since the late defeat of Centeno, which was entirely attributed to the talents of Carvajal. About the same time Centeno joined the president with more than thirty horse, who had accompanied him ever since the defeat of Guarina. Continuing his march amid considerable difficulties, owing to the scarcity of provisions, the president at length reached the province of Andahuaylas, where he judged it proper to remain during the winter, on account of the violent rains which fell night and day almost without ceasing, by which the tents were all rotted. The maize which they procured as food for the troops was all wet and spoiled, by which a considerable number of the soldiers were afflicted with dysentery, of which some died, notwithstanding the care taken of the sick by Francisco de la Rocha, a Trinitarian monk, who acted as physician to the army. Although there were above four hundred sick at one time, so great was the care bestowed, that they were as well attended and as plentifully supplied with medicines as if in a populous city, insomuch that they almost all recovered.
