Before commencing the assault, Vaca de Castro addressed a few remarks to his soldiers, in order to remove any hesitation that some might yet feel, who recollected the displeasure shown by the emperor to the victors as well as the vanquished after the battle of Salinas. He told them that their enemies were rebels. They were in arms against him. the representative of the Crown, and it was his duty to quell this rebellion and punish the authors of it. He then caused the law to be read aloud, proclaiming the doom of traitors. By this law, Almagro and his followers had forfeited their lives and property, and the governor promised to distribute the latter among such of his men as showed the best claim to it by their conduct in the battle. This last politic promise vanquished the scruples of the most fastidious; and, having completed his dispositions in the most judicious and soldier-like manner, Vaca de Castro gave the order to advance.21As the forces turned a spur of the hills, which had hitherto screened them from their enemies, they came in sight of the latter, formed along the crest of a gentle eminence, with their snow-white banners, the distinguishing color of the Almagrians, floating above their heads, and their bright arms flinging back the broad rays of the evening sun.
Almagro's disposition of his troops was not unlike that of his adversary.
In the centre was his excellent artillery, covered by his arquebusiers and spearmen; while his cavalry rode on the flanks. The troops on the left he proposed to lead in person. He had chosen his position with judgment, as the character of the ground gave full play to his guns, which opened an effective fire on the assailants as they drew near. Shaken by the storm of shot, Vaca de Castro saw the difficulty of advancing in open view of the hostile battery. He took the counsel, therefore, of Francisco de Carbajal, who undertook to lead the forces by a circuitous, but safer, route. This is the first occasion on which the name of this veteran appears in these American wars, where it was afterwards to acquire a melancholy notoriety. He had come to the country after the campaigns of forty years in Europe, where he had studied the art of war under the Great Captain, Gonsalvo de Cordova. Though now far advanced in age, he possessed all the courage and indomitable energy of youth, and well exemplified the lessons he had studied under his great commander.
Taking advantage of a winding route that sloped round the declivity of the hills, he conducted the troops in such a manner, that, until they approached quite near the enemy, they were protected by the intervening ground. While thus advancing, they were assailed on the left flank by the Indian battalions under Paullo, the Inca Manco's brother; but a corps of musketeers, directing a scattering fire among them, soon rid the Spaniards of this annoyance. When, at length, the royal troops, rising above the hill, again came into view of Almagro's lines, the artillery opened on them with fatal effect. It was but for a moment, however, as, from some unaccountable cause, the guns were pointed as such an angle, that, although presenting an obvious mark, by far the greater part of the shot passed over their heads. Whether this was the result of treachery, or merely of awkwardness, is uncertain. The artillery was under charge of the engineer, Pedro de Candia. This man, who, it" may be remembered, was one of the thirteen that so gallantly stood by Pizarro in the island of Gallo, had fought side by side with his leader through the whole of the Conquest. He had lately, however, conceived some disgust with him, and had taken part with the faction of Almagro. The death of his old commander, he may perhaps have thought, had settled all their differences, and he was now willing to return to his former allegiance.
At least, it is said, that, at this very time, he was in correspondence with Vaca de Castro. Almagro himself seems to have had no doubt of his treachery. For, after remonstrating in vain with him on his present conduct, he ran him through the body, and the unfortunate cavalier fell lifeless on the field. Then, throwing himself on one of the guns, Almagro gave it a new direction, and that so successfully, that, when it was discharged, it struck down several of the cavalry.22The firing now took better effect, and by one volley a whole file of the royal infantry was swept off, and though others quickly stepped in to fill up the ranks, the men, impatient of their sufferings, loudly called on the troopers, who had halted for a moment, to quicken their advance.23This delay had been caused by Carbajal's desire to bring his own guns to bear on the opposite columns. But the design was quickly abandoned;the clumsy ordnance was left on the field, and orders were given to the cavalry to charge; the trumpets sounded, and, crying their war-cries, the bold cavaliers struck their spurs into their steeds, and rode at full speed against the enemy.
