skirmish, the president marched down from the mountain with the main body of his army, in the direction of Cuzco, under cover of the hill on which the skirmish had taken place; and, to distract the attention of the enemy, a small detachment of cavalry and infantry was ordered to advance in view of the insurgent camp from that hill.  On the arrival of Valdivia and Alvarado at the top of the hill, observing that it was possible to cannonade the camp of the enemy from that place, they sent orders to Gabriel de Royas to bring up the artillery.  On this occasion, De Royas promised a reward of five hundred crowns for each ball that should reach the enemy:  In fact he paid that sum about a year afterwards to one of his gunners, who sent a ball through the tent of Gonzalo, which was exceedingly conspicuous, by which one of his pages was slain.  In consequence of this incident, Gonzalo ordered all the tents to be struck, that they might not serve as marks for the cannoneers of the president.  He likewise ordered his own artillery to commence firing, and drew up his army in order of battle, taking his own station at the head of his cavalry, which was commanded by the licentiate Cepeda and Juan d’Acosta.  Carvajal was at the head of the infantry, having under him the captains Juan de la Torre, Diego Guillen, Juan Velasquez de Guevara, Francisco Maldonado, and Sebastian de Vergara.  Pedro de Soria commanded his artillery.  When the insurgent army was drawn up in order of battle, the numerous Indians that were attached to it quitted the camp, and posted themselves in view of both armies on the slope of a neighbouring hill.

While the artillery on both sides kept up a constant fire, the royalist army descended from the mountain without keeping any regular order, and in all possible haste, the cavalry all on foot leading their horses, both on account of the ruggedness of the ground and the better to avoid the cannonade from the enemy, as they had no shelter from the balls.  Immediately on getting down to the plain, the troops were drawn up in order of battle; the infantry in two battalions in the centre, and the cavalry on the two wings.  The cavalry of the left wing was commanded by the captains Juan Saavedra, Diego de Mora, Rodrigo Salazar, and Francisco Hernandez de Aldana.  The royal standard was displayed by the licentiate Carvajal in the right wing, in which likewise were posted the captains Don Pedro de Cabrera, Alfonso Mercadillo, and Gomez de Alvarado.  The infantry marched between the wings of horse, but a little farther in advance, under the captains Ramirez, De Castro, De Solis, Cardenas, Menezes, Mosquera, De la Cerna, Urbina, Aliaga, De Robles, De Arias, and De Olmos.  A little in advance of the infantry, Alfonso de Mendoza marched with his troop of horse to commence the attack, accompanied by Centeno, who was determined to exert himself on this occasion in revenge for his defeat at Guarina.  Pedro de Villavicentio acted as serjeant-major or
