I was then in Cuzco, though a boy, when Giron and his soldiers made their first disturbance; and I was present also about three years afterwards at their second mutiny; and, though I had not even then attained the age of a young man, I was sufficiently able to notice and understand the observations and discourses of my father on the various events which occurred; and I can testify that the soldiers behaved in so proud and insolent a manner that the magistrates were forced to take notice of their conduct. The soldiers thought proper to be much offended on this occasion, pretending that no one ought to have any authority over them except Giron under whose command they had inlisted; and they carried their mutinous insolence to such a height as to assemble in arms at the house of their commander to protect themselves against the magistrates. When this mutiny was known in the city, the magistrates and citizens found themselves obliged to arm, and being joined by many soldiers who were not of the faction, they took post in the market-place. The mutineers drew up likewise in the street where Giron's house stood, at no great distance from the market-place; and in this manner both parties remained under arms for two days and nights, always on the point of coming to action; which had certainly been the case if some prudent persons had not interposed between them, and prevailed on the magistrates to enter into a treaty for compromising their differences. The most active persons on this occasion were Diego de Silva, Diego Maldonado the rich, Garcilasso de la Vega my father, Vasco de Guevara, Antonio Quinnones, Juan de Berrio, Jeronimo de Loyasa, Martin de Meneses, and Francisco Rodriguez. By their persuasions the regidor Juan de Saavedra and Captain Francisco Hernandez Giron were induced to meet in the great church, on which occasion the soldiers demanded four hostages for the security of their commander. In this conference Giron behaved with so much insolence and audacity, that Saavedra had assuredly arrested him if he had not been restrained from respect for the hostages, of whom my father was one. In a second conference in the evening, under the same precautions, Giron agreed to remove his soldiers from the city, to give up eight of the most mutinous of his soldiers to the magistrates, and even to make compearance in person before the court to answer for his conduct during the mutiny.

On being made acquainted with this agreement, the soldiers were exceedingly enraged; and if Giron had not pacified them with soothing words and promises they had certainly attacked the loyal inhabitants, the consequences of which might have been exceedingly fatal. The mutineers amounted to two hundred effective well-armed men, of desperate fortunes, while the loyalists consisted of only eighty men of quality, all the rest being rich merchants not inured to arms. But it pleased God to avert the threatened mischief, at the prayers and vows of the priests, friars and devout women of the city. The mutineers were under arms all night, setting regular guards and sentinels as in the presence of an enemy; and in the morning, when Saavedra saw that Giron had not marched from the city according to agreement, he sent a warrant to bring him before his tribunal. As Giron suspected that his men might not permit him to obey the warrant, he walked out in his morning gown, as if only going to visit a neighbour; but went directly to the house of Saavedra, who committed him to prison. On this intelligence being communicated to the soldiers, they immediately dispersed, every one shifting for himself as he best could. The eight men who were particularly obnoxious took sanctuary in the Dominican convent, and fortified themselves in the tower of the church, where they held out for several days, but were at last obliged to surrender. They were all punished, but not in that exemplary manner their rebellious conduct deserved; and the tower was demolished, that it might not be used in the same manner in future.

After the dispersion of the mutineers and the punishment of the most guilty, Giron was released on his solemn engagement to make his appearance before the royal audience at Lima to answer for his conduct. He went there accordingly, and was committed to prison; but after a few days was permitted to go out as a prisoner at large, confining himself to the city of Lima. He there married a young virtuous noble and beautiful lady, with whom he went to reside at Cuzco, where he associated with none but soldiers, avoiding all society with the citizens as much as possible.

About two years afterwards several soldiers residing in Cuzce, entered into a new plot to raise disturbances in the kingdom, and were eager to find some proper person to choose as their leader. At length this affair came to be so openly talked of that it reached the knowledge of Saavedra, who was required to take cognizance of the plot and to punish the ringleaders; but he endeavoured to excuse himself, being unwilling to create himself enemies, alleging that it more properly belonged to the jurisdiction of the court of audience. When this affair was reported to the oydors at Lima, they were much displeased with the conduct of Saavedra, and immediately appointed the marshal Alonzo de Alvarado to supersede him in the office of regidor or mayor of Cuzco, giving Alvarado an especial commission to punish the insolence and mutinous conduct of the soldiers, to prevent the evil from getting to an unsupportable height. Immediately on taking possession of his office, Alvarado arrested some of the soldiers; who, to screen themselves, impeached Don Pedro de Puertocarrero as a principal instigator of their mutinous proceedings. After a minute examination, Francisco de Miranda, Alonzo Hernandez Melgarejo, and Alonzo de Barrienuevo were capitally punished as chief ringleaders in the conspiracy; six or seven others were banished from Peru, and all the rest made their escape. Puertocarrero made an appeal to the royal audience, by whom he was set at liberty.

These new commotions, and others of more importance which shall be noticed in the sequel, proceeded in a great measure from the imprudent conduct of the judges themselves, by enforcing the observance of the obnoxious regulations which had formerly done so much evil during the government of the viceroy Blasco Nunnez Vela. Just before his departure from Peru, the president Gasca had received fresh orders from his majesty to free the Indians from services to their lords: But having experienced that this had occasioned the most dangerous commotions in the country, he very wisely commanded before his departure that the execution of this new order should be suspended. The judges however, saw this matter in a different light, and circulated their commands over the whole kingdom to enforce this new royal order; which gave occasion to the mutinous and disorderly behaviour of the soldiery, who were encouraged in their rebellious disposition by many persons of consideration, the possessors of allotments of lands and Indians, who considered themselves aggrieved.

About this time Don Antonio de Mendoza, the viceroy of Mexico, was appointed viceroy of Peru, and landed at Lima, where he was received with great demonstration of joy and respect. He was accompanied on this occasion by his son, Don Francisco de Mendoza, afterwards general of the galleys in Spain. Don Antonio was a nobleman of much sanctity, and had greatly impaired his health by long abstinence and frequent acts of penance; insomuch that his natural heat began to fail, and he was obliged to use violent exercise to keep him warm, even in the hot climate of Lima. In consequence of his want of health, he deputed his son Don Francisco to make a progress through all the cities of the kingdom, from Lima to Las Charcas and Potosi, to bring him back a faithful representation of the state and condition of the kingdom and its mines, to be laid before his majesty; and, after his return to Lima, Don Francisco was sent into Spain in 1552, to communicate an account of the whole kingdom to the emperor.
