On the return of the marquis to Lima, he made additional levies of troops; giving out openly that he was reduced to take up arms against Almagro, who had invaded his government. In a few days he assembled an army of seven hundred men, among whom was a considerable body of musqueteers, which had been brought from Flanders with the necessary arms and ammunition by Pedro de Vergera, along with the troops of Diego de Fuenmayor. Hitherto there had not been a sufficient number of musquets in Peru to form entire companies of that species of troops; but on the present occasion the marquis was enabled to arm two companies with that powerful weapon, one of which was commanded by the before named Pedro de Vergera, who had been formerly sent to discover the province of Bracamoras. Nugno de Castro was appointed captain of the other company of musqueteers. Diego de Urbina, nephew of the maestre de campo Juan de Urhina, was made captain of the pikemen. Diego de Roias, Peranzures, and Alfonso de Mercadillo, were appointed captains of horse: Pedro de Valdivia maestre de campo, and Antonio de Vilalva sergeant-major, who was son of Colonel Vilalva.
About this time, Alonso de Alvarado and Gonzalo Pizarro, who remained prisoners in Cuzco[14], made their escape from prison, and joined the marquis with above seventy men whom they had persuaded to accompany them, bringing likewise along with them as prisoner Gabriel de Roias the lieutenant of Almagro. The arrival of these officers gave much satisfaction to the marquis, both on account of their escape from danger, and because the reinforcement they brought along with them gave great encouragement to his troops. He appointed his brother Gonzalo lieutenant-general of his army, and Alonso Alvarado maestre de campo, or major-general of the cavalry. When Almagro learnt that his prisoners had escaped, and the numerous forces which the marquis had procured, he became desirous of an accommodation, for which purpose he sent Alfonso Enriquez, Diego Nugnez de Mercadura the factor, and Juan de Guzman treasurer, to the marquis to desire an interview, at which they might regulate every thing that was in dispute between them. After several messages and proposals, the marquis proposed to refer the whole matter to the umpirage of Francisco de Bovadilla, provincial of the order of Mercy, to which Almagro consented.
