One day several of the citizens came from the camp to the city, under the authority of a pass, to procure such provisions and other articles as they stood in need of, the principal persons among whom were Nicolas de Ribeira, who was alcalde or police judge of the city, Vasco de Guevara, Hernando Bravo de Lagunas, Francisco de Ampuero, Diego Tinoco, Alfonzo Ramirez de Sosa, Francisco de Barrionueva, Alfonzo de Barrionuevo, Martin de Menezes, Diego d'Escobar, and some others. After they had collected the articles of which they were in want, they left the city with their horses arms and servants; but, instead of returning towards the camp, they went off in the road for Truxillo. Being noticed by some spies, who gave immediate notice to Gonzalo, he caused them to be pursued by Juan de la Torre with a party of mounted musqueteers. At the distance of eight leagues from Lima, De la Torre came up with Vasco de Guevara and Francisco Ampuero, who had fallen behind with the intention of acting as a kind of rear guard, to give notice to the rest in case of a pursuit. They defended themselves courageously, and as their enemies could not take any certain aim, it being under night, they contrived to make their escape unwounded. De la Torre and his men found themselves unable to continue the pursuit with any chance of success, as their horses were already completely tired with their rapid march from camp. They returned, therefore, believing that, even if they were to get up with the fugitives, they would be unable to take them by force, as they were all men of quality, who would rather be slain than surrender. On their way back to camp, they fell in with Hernando Bravo, who had fallen behind his companions, and on bringing him a prisoner to Gonzalo he was ordered to immediate execution. Donna Ynez Bravo, who was sister to the prisoner and wife to Nicolas de Ribeira, one of the fugitives, on hearing the situation of her brother, hastened to the camp accompanied by her father, and threw herself at the feet of Gonzalo, whom she earnestly implored to spare the life of her brother. Being one of the most beautiful women of the country, and of the highest rank, and being seconded by most of the officers who served under Gonzalo, he at length allowed himself to be prevailed on to pardon her brother, who was the only person, during the whole subsistence of his usurpation, whom he forgave for a similar offence. On granting this pardon, Alfonzo de Caceres, one of the captains under Gonzalo, kissed his hand saying: "Illustrious prince! accursed be he who abandons you, or hesitates to sacrifice his life in your service." Yet, within three hours afterwards, Hernando Bravo and several others made their escape from the camp. Among these who now deserted were several persons of consideration who had attached themselves to Gonzalo from the very commencement of the troubles, so that their defection gave him infinite vexation and alarm, insomuch that hardly any one dared to speak to him, and he issued peremptory orders to put to death every person who might be found beyond the precincts of the camp.

On the same night, Captain Martin de Robles sent a message to Diego Maldonado, who had been alcalde of Cuzco, usually called the rich, intimating that Gonzalo had resolved in a consultation with his officers to put him to death. Maldonado very readily believed this information, as he had formerly been one of the inhabitants of Cuzco who made offer of their services to the late viceroy. Likewise, although then pardoned by Gonzalo, whom he accompanied in the march to Quito against the viceroy, he had fallen under new suspicions, and had even been put to the torture, on account of a letter which was dropt near Gonzalo, containing some very unpleasant truths; and although the real authors of that letter had been afterwards discovered, Maldonado could never forget the treatment he had suffered at that time. Besides this, he was the intimate friend of Antonio Altamirano, whom Gonzalo had recently put to death. Considering all these circumstances, Maldonado was so thoroughly convinced of the imminent danger in which he stood, that he immediately quitted his tent with only his sword and cloak, not even taking time to saddle a horse, though he had several good ones, or speaking to any of his servants. Though a very old man, he walked as fast as possible all night in a direction towards the sea, and concealed himself in the morning among some tall reeds near the shore about three leagues from where the ships of Aldana lay at anchor. As he was much afraid of being pursued, he revealed his situation to an Indian who happened to be near; and whom he prevailed upon to construct a float of reeds and straw, on which the Indian carried him on board one of the ships.

In the morning, Martin de Robles went to the tent of Maldonado; and finding him withdrawn as he expected, he immediately waited on Gonzalo, whom he informed of the circumstance, adding, "As the army was diminishing daily by the number and quality of the fugitives, he begged leave to advise that they should quit the present camp, and march into the interior provinces, as formerly agreed upon, without granting permission to any one to go into the city of Lima, lest many more might use that pretence for an opportunity to desert. Several of his own company, he said, had applied for leave to go into the city, to procure provisions; but he considered it better for himself to go therewith a detachment of soldiers to collect the provisions and necessaries required, that he might keep all his men in sight, and that he proposed on this occasion to take Maldonado from the Dominican convent, where he understood he had taken refuge, and to bring him a prisoner to the camp, where he ought to undergo condign punishment, as a warning to others." Gonzalo approved all that was said on this occasion by De Robles, in whom he had great confidence as a person who had taken part with him in all the past troubles, and desired him to act in the way he proposed. De Robles accordingly, taking all his own horses and attendants and those belonging to Maldonado, took along with him to Lima all the soldiers of his company in whom he could confide. After collecting such provisions and other necessaries as might serve his purpose, he set off for Truxillo with thirty armed horsemen, declaring publickly that Gonzalo was a tyrant and usurper, that all good subjects were bound to obey the orders of his majesty, and that he was resolved to join the president.

When this serious defection became known in the camp, it was universally believed that the army would soon disperse, and that Gonzalo would be massacred. Gonzalo endeavoured to restore order and confidence among his troops, pretending to care little for those who had deserted him; yet resolved to decamp next morning. That very night, Lope Martin, an inhabitant of Cuzco, deserted almost in sight of the whole army. Next morning Gonzalo quitted his present camp, and marched about two leagues to a new camp near an aqueduct, taking every precaution to prevent his people from deserting; believing that his principal danger on that account would be got over if he were once ten or twelve leagues from Lima. The licentiate Carvajal was appointed to take charge of the night guard, with strict injunctions to prevent desertion: But even he, in the middle of the night, quitted the camp accompanied by Paulo Hondegardo, Marco de Retamoso, Pedro Suarez d'Escovedo, Francisco de Miranda, Hernando de Vargas, and several others belonging to his company. These men went in the first place to Lima, whence they took the road towards Truxillo. A few hours afterwards, Gabriel de Roias left the camp, accompanied by his nephews Gabriel Bermudez and Gomez de Roias and several other persons of quality. These men left the camp unseen by any one, as they went through the quarter which had been confided to the charge of the licentiate Carvajal.

In the morning, Gonzalo was much distressed on learning the events of the past night, and more especially by the desertion of the licentiate Carvajal, whom he had disobliged by superseding him in the command which had been conferred on Juan d'Acosta, and by refusing him his niece Donna Francisca in marriage. The departure of the licentiate had a very bad effect on the minds of the troops; as they knew he was entrusted with all Gonzalos secrets, and had been greatly in his confidence ever since the death of the viceroy whom he had slain in the battle of Quito. Carvajal left to the value of more than 15,000 crowns in the camp, in gold silver and horses, all of which was immediately confiscated and divided among the soldiers: But the army was convinced he would not have abandoned so much valuable property, unless he had been satisfied that the affairs of Gonzalo were in a very bad condition, both in regard to power of resisting the president, and in respect of the right and justice of his pretensions. So great was the defection in the camp, that the greater part of the troops had resolved to disperse; and next morning, when the army had begun its march, two cavaliers, named Lopez and Villadente, quitting the ranks and causing their horses to vault in sight of the whole army, they cried, out aloud, "Long live the king, and let the tyrant die!" These men trusted, to the speed of their horses; and Gonzalo was so exceedingly suspicious of every one, that he expressly forbid these men to be pursued, being afraid that many might use that pretence for joining them. He continued his march accordingly, in all haste by the road of the plain country, leading towards Arequipa; in which march several of his musqueteers and others deserted, although he hanged ten or twelve persons of consideration in the course of three or four days. At length his force was reduced to two hundred men, and he was in continual dread that in some false alarm all his remaining men might disperse. Continuing his march, he at length came to the province of Nasca, about fifty leagues from Lima.

After Gonzalo had gone to a considerable distance from Lima, Don Antonio de Ribeira, Martin Pizarro, Antonio de Leon, and some other inhabitants of Lima, who as old and infirm had been allowed by Gonzalo to remain behind the army on giving up all their horses and arms, erected the standard of the city, and, assembling the small number of inhabitants that remained in the great square, they publickly declared for his majesty in their own names and in the names of all the loyal citizens of the city. After proclaiming the new regulations and orders of the president, the general amnesty granted by the king, and the abrogation of the obnoxious regulations, they sent notice of all the recent events to Aldana, who still remained on the coast to receive and protect all who were inclined to quit the party of the insurgents. At the same time, and for the same purpose, Juan Alfonso Palamino had landed with fifty men, yet keeping his boats always in readiness to reimbark, in case of the return of Gonzalo. Aldana likewise placed an advanced picket of twelve horsemen, of those who had deserted from the insurgents, on the road towards Arequipa, to bring him timely notice of any thing that might occur in that quarter, with orders to return with all speed in case of the enemy making a countermarch, or of any important event. Aldana likewise gave orders to Captain Alfonzo de Caceres to remain at Lima, to collect any of the deserters from Pizarro that might come there; and he dispatched Juan Yllanez in one of his vessels along the coast, with orders to land a monk and a soldier in some secure place, to carry dispatches to Centeno, announcing the events that had occurred at lima, and to furnish him with copies of the royal orders and general amnesty, and to communicate similar intelligence at Arequipa. He sent likewise several intelligent persons by land to Arequipa, with letters to different persons of consideration, and to carry orders and instructions to the captains Alfonzo de Mendoza and Juan de Silveira at La Plata. By means of the Indians of Jauja, who belonged to him, Aldana transmitted letters and copies of the amnesty to several of those persons who accompanied Juan d'Acosta, that the royal clemency might be made known in all parts of Peru. Most of these measures succeeded, and produced material advantages as will appear in the sequel. In the mean time, Lorenzo de Aldana remained on board ship, with about an hundred and fifty men, issuing such orders as seemed necessary in the present state of affairs.

It was soon learnt that Gonzalo received regular advices of ever thing that occurred, and great care was likewise taken by Aldana to procure intelligence of all that passed in the camp of the insurgents; so that every day messengers went and came between both parties, and both were continually endeavouring to mislead each other by false reports. Accordingly it was reported one day that Gonzalo and his troops Were in full march for Lima, which occasioned much confusion and dismay in that city; but it was known afterwards that this rumour had been purposely spread by Gonzalo and his lieutenant-general, on purpose to prevent Aldana from pursuing them, a measure of which they were much afraid. In this unpromising state of his affairs, great numbers of the adherents of Gonzalo abandoned him, believing that he could not resist the power of his enemies. Such of them as had horses took the road to Truxillo; and all the rest endeavoured to reach the ships of Aldana, concealing themselves as well as they could in retired places till they might ascertain that Gonzalo had proceeded farther on his march, which indeed he continued to do with much precipitation. When he had proceeded to a considerable distance from Lima, all those who had abandoned him flocked to that city, and every day some fresh deserters came there, by which means Aldana got accurate intelligence of the proceedings of Gonzalo, who was reported to be in continual dread of being put to death by his own men. After the flight of the licentiate Carvajal and Gabriel de Roias, Gonzalo made no farther use of the royal standard, only displaying that which contained his own arms. His cruelty increased with his disappointment, insomuch that not a day passed in which he did not put some one to death. He took extraordinary precautions for his own personal safety, which were so far effectual, but every effort to prevent desertion was unavailing.

Lorenzo de Aldana sent intelligence of all these matters to the president, by means of messengers dispatched both by sea and land, earnestly urging him to come into Peru as quickly as possible, as the insurgent party seemed at so low an ebb that nothing was wanting but his presence to make it fall entirely in pieces and submit without a struggle. On the 9th. of September 1547, when assured that Gonzalo had retreated eighty leagues from Lima, Aldana landed with all his officers and all the inhabitants of Lima that had taken shelter on board his ships. He was received on shore with every demonstration of joy and respect, every one who was able appearing in arms to do him honour. Having appointed Juan Fernandez to the command of the ships, he took charge of the vacant government of Lima, where he made every possible preparation for carrying on the war, collecting arms ammunition and all other necessaries.

Some time after the departure of Juan d'Acosta from Lima for Cuzco by the mountain road, as already mentioned, at the head of three hundred men well armed and equipped, he got notice that Gonzalo Pizarro had abandoned that city; on which he sent Fra Pedro, a monk of the order of Mercy, to Gonzalo, to demand instructions for his ulterior proceedings. Pizarro sent back the monk with directions for Acosta to join him at a certain place. On his return to Acosta, accompanied by a person named Gonzalo Muquos, after delivering his dispatches, Friar Pedro gave him an account of all that had happened in the army of Gonzalo, and in particular of the great number of men that had deserted from him; which Acosta had not before learnt, though several of his soldiers had received the intelligence by letters brought to them by the Indians who frequented the camp, but which they dared not to communicate to each other. On the present occasion, the messengers from Gonzalo recommended to Acosta to keep this matter as secret as possible till such time as he should join Gonzalo. Acosta therefore, gave out that he had received favourable intelligence from the monk, and that Gonzalo had been successful on several occasions, being daily joined by many additional soldiers; and, as he had found it convenient and necessary to send off many confidential persons in various directions, these persons pretended to have deserted from Gonzalo by way of stratagem, on purpose, to gain possession of the ships commanded by Aldana. All this however was insufficient to disguise the truth from many of the followers of Aldana, particularly Paëz de Sotomayor, his major-general, and Martin d'Olmos one of his captains; who, coming to a knowledge of the real state of affairs, entered into a resolution of putting D'Acosta to death. They formed this resolution unknown to each other, as no one at this time dared to avow his sentiments to any other person, for fear of being put to death; yet, from certain indications, they began to suspect each other of entertaining similar sentiments, and at length opened themselves reciprocally, and communicated their purposes to several soldiers in whom they confided. Just when they were about to have put their enterprize into execution, Sotomayor got notice that D'Acosta was holding a secret conference in his tent with two of his captains, and that he had doubled his ordinary guard. From these circumstances, Sotomayor concluded that their conspiracy, having been revealed to several persons, had been betrayed to Acosta. He took therefore prompt measures to inform all his confederates, and both he and they took horse without delay, and left the camp in sight of all the army, to the number of thirty-five in all; among whom, besides Sotomayor and D'Olmos, the principal persons were Martin d'Alarzon who carried the grand standard, Hernando de Alvarado, Alfonzo Regel, Antonio de Avila, Garcias Gutierrez d'Escovedo, and Martin Monje; who, with all who went off on this occasion, were men of consideration and of much experience in the affairs of Peru. These men took immediately the road for Guamanga, and used such expedition that, though Acosta sent off sixty mounted musqueteers to pursue them, they made their escape in safety.

Acosta caused immediate investigations to be made in regard to such as had participated in this plot, and ordered several persons to be hanged who were proved to have known its circumstances: some others in the same predicament he detained prisoners, and dissembled with the rest who had been implicated, pretending not to know that they had participated in the conspiracy: Yet, during his march towards Cuzco, he put to death several of those of whom he was suspicious, and others who endeavoured to desert. On his arrival at Cuzco, he displaced all the magistrates who had been appointed by Centeno, nominating others in their stead in whom he thought he could confide, and appointed Juan Velasquez de Tapia to take the chief direction of affairs in that city and province; and having regulated every thing to his mind, he resumed his march for Arequipa to join Gonzalo, according to his directions. In this latter part of his march, about thirty of his men deserted from him, by two or three at a time, all of whom went directly to Lima where they joined Lorenzo de Aldana. Besides these, when Acosta had got about ten leagues beyond Cuzco, Martin de Almandras abandoned him with twenty of the best soldiers of his small army, and returned to Cuzco, where he found a sufficient number of the inhabitants disposed to join him in returning to their duty, and in concurrence with whom he deposed the magistracy appointed by Acosta, one of whom he sent away prisoner to Lima, and established a new set in the name of his majesty. Finding that the number of his followers diminished from day to day, Acosta accelerated his march as much as possible, both for his own security and to serve the insurgent cause in which he was engaged. Out of three hundred well armed and excellently equipped men, with whom he had set out from Lima, only one hundred remained with him on his arrival at Arequipa. He found Gonzalo Pizarro at that place, with only about three hundred and fifty men, who a very short while before had a fine army of fifteen hundred, besides all those who were dispersed in different parts of Peru under various captains, all of whom were then under his orders. Gonzalo was now exceedingly irresolute as to his future proceedings; being too weak to wait the attack of the royalists, who continually augmented in their numbers, and yet deeming it dishonourable to fly or to endeavour to conceal himself.
