After traversing the terrible desert, Almagro reached the ancient town of Arequipa, about sixty leagues from Cuzco. Here he learned with astonishment the insurrection of the Peruvians, and further, that the young Inca Manco still lay with a formidable force at no great distance from the capital. He had once been on friendly terms with the Peruvian prince, and he now resolved, before proceeding farther, to send an embassy to his camp, and arrange an interview with him in the neighborhood of Cuzco.
Almagro's emissaries were well received by the Inca, who alleged his grounds of complaint against the Pizarros, and named the vale of Yucay as the place where he would confer with the marshal. The Spanish commander accordingly resumed his march, and, taking one half of his force, whose whole number fell somewhat short of five hundred men, he repaired in person to the place of rendezvous; while the remainder of his army established their quarters at Urcos, about six leagues from the capital.7
The Spaniards in Cuzco, startled by the appearance of this fresh body of troops in their neighborhood, doubted, when they learned the quarter whence they came, whether it betided them good or evil. Hernando Pizarro marched out of the city with a small force, and, drawing near to Urcos, heard with no little uneasiness of Almagro's purpose to insist on his pretensions to Cuzco. Though much inferior in strength to his rival, he determined to resist him.
Meanwhile, the Peruvians, who had witnessed the conference between the soldiers of the opposite camps, suspected some secret understanding between the parties, which would compromise the safety of the Inca. They communicated their distrust to Manco, and the latter, adopting the same sentiments, or perhaps, from the first, meditating a surprise of the Spaniards, suddenly fell upon the latter in the valley of Yucay with a body of fifteen thousand men. But the veterans of Chili were too familiar with Indian tactics to be taken by surprise. And though a sharp engagement ensued, which lasted more than an hour, in which Orgonez had a horse killed under him, the natives were finally driven back with great slaughter, and the Inca was so far crippled by the blow, that he was not likely for the present to give further molestation.8
Almagro, now joining the division left at Urcos, saw no further impediment to his operations on Cuzco. He sent, at once, an embassy to the municipality of the place, requiring the recognition of him as its lawful governor, and presenting at the same time a copy of his credentials from the Crown. But the question of jurisdiction was not one easy to be settled, depending, as it did, on a knowledge of the true parallels of latitude, not very likely to be possessed by the rude followers of Pizarro. The royal grant had placed under his jurisdiction all the country extending two hundred and seventy leagues south of the river at Santiago, situated one degree and twenty minutes north of the equator. Two hundred and seventy leagues on the meridian, by our measurement, would fall more than a degree short of Cuzco, and, indeed, would barely include the city of Lima itself. But the Spanish leagues, of only seventeen and a half to a degree,9 would remove the southern boundary to nearly half a degree beyond the capital of the Incas, which would thus fall within the jurisdiction of Pizarro.10 Yet the division-line ran so close to the disputed ground, that the true result might reasonably be doubted, where no careful scientific observations had been made to obtain it; and each party was prompt to assert, as they always are in such cases, that its own claim was clear and unquestionable.11
Thus summoned by Almagro, the authorities of Cuzco, unwilling to give umbrage to either of the contending chiefs, decided that they must wait until they could take counsel—which they promised to do at once—with certain pilots better instructed than themselves in the position of the Santiago. Meanwhile, a truce was arranged between the parties, each solemnly engaging to abstain from hostile measures, and to remain quiet in their present quarters.
The weather now set in cold and rainy. Almagro's soldiers, greatly discontented with their position, flooded as it was by the waters, were quick to discover that Hernando Pizarro was busily employed in strengthening himself in the city, contrary to agreement. They also learned with dismay, that a large body of men, sent by the governor from Lima, under command of Alonso de Alvarado, was on the march to relieve Cuzco. They exclaimed that they were betrayed, and that the truce had been only an artifice to secure their inactivity until the arrival of the expected succours. In this state of excitement, it was not very difficult to persuade their commander—too ready to surrender his own judgment to the rash advisers around him—to violate the treaty, and take possession of the capital.12
Under cover of a dark and stormy night (April 8th, 1537), he entered the place without opposition, made himself master of the principal church, established strong parties of cavalry at the head of the great avenues to prevent surprise, and detached Orgonez with a body of infantry to force the dwelling of Hernando Pizarro. "That captain was lodged with his brother Gonzalo in one of the large halls built by the Incas for public diversions, with immense doors of entrance that opened on the plaza. It was garrisoned by about twenty soldiers, who, as the gates were burst open, stood stoutly to the defence of their leader. A smart struggle ensued, in which some lives were lost, till at length Orgonez, provoked by the obstinate resistance, set fire to the combustible roof of the building. It was speedily in flames, and the burning rafters falling on the heads of the inmates, they forced their reluctant leader to an unconditional surrender. Scarcely had the Spaniards left the building, when the whole roof fell in with a tremendous crash.13
Almagro was now master of Cuzco. He ordered the Pizarros, with fifteen or twenty of the principal cavaliers, to be secured and placed in confinement. Except so far as required for securing his authority, he does not seem to have been guilty of acts of violence to the inhabitants,14 and he installed one of Pizarro's most able officers, Gabriel de Rojas, in the government of the city. The municipality, whose eyes were now open to the validity of Almagro's pretensions, made no further scruple to recognize his title to Cuzco.
The marshal's first step was to send a message to Alonso de Alvarado's camp, advising that officer of his occupation of the city, and requiring his obedience to him as its legitimate master. Alvarado was lying, with a body of five hundred men, horse and foot, at Xauxa, about thirteen leagues from the capital. He had been detached several months previously for the relief of Cuzco; but had, most unaccountably, and, as it proved, most unfortunately for the Peruvian capital, remained at Xauxa with the alleged motive of protecting that settlement and the surrounding country against the insurgents.15 He now showed himself loyal to his commander; and, when Almagro's ambassadors reached his camp, he put them in irons, and sent advice of what had been done to the governor at Lima.
