After the president had passed the mountains and pitched his camp on the descent towards the plain, within view of the insurgents, Gonzalo drew up his army in order of battle, and caused some discharges to be made from his cannon and musquetry. On that day there arose so thick a mist, that the scouts and spies of the two armies often came against each other unexpectedly. Seeing that the insurgents were disposed to await his attack, or even to give battle, the president was inclined to defer bringing matters to that extremity for some time, in the hope that a considerable number of the enemy might come over to him if they could find an opportunity. Yet, as the season was exceedingly cold, even accompanied with strong frost, and as wood could not be procured for making fires, and provisions were scarce, it was impossible to remain long in a state of inaction. The army of Gonzalo was not subject to any of these inconveniencies, having plenty of provisions brought regularly from Cuzco, and being encamped in a comfortable and temperate situation in comparison with the position of the president, whose camp was on the slope of the mountain, while that of the insurgents was in the plain or valley below. Such is the difference in the temperature of Peru at very inconsiderable distances, that on the mountains a severe cold is experienced, accompanied by frost and snow, while only at eight or ten miles distance in the valley the inhabitants are obliged to use precautions to relieve them from excessive heat.
