The governor went afterwards to Cuzco, where he brought Don Diego to trial, and ordered him to be beheaded.  Diego de Mendez, Gomez Perez, and another, made their escape from prison into the mountains of the Andes, where they were kindly received by Manco Capac the fugitive Inca, who had taken refuge in an inaccessible country.  The Inca was much grieved on learning the death of Don Diego, whom he was greatly attached to, and to whom he had sent several coats of mail, corselets, cuirasses, and other arms, which he had taken from the Spaniards whom he defeated and slew, at the time when he went by order of the marquis to relieve Gonzalo and Juan Pizarro, then besieged in Cuzco.

After the death of Don Diego and the entire dispersion of his adherents, by which peace was restored through the whole country, the governor did not consider it proper to disband his army, as he had not sufficient funds to reward them according to their services; for which reason he resolved to send them in different detachments to make discoveries and conquests.  Captain Vergara and his troops were accordingly sent back to complete the conquest of the Bracamoras.  The Captains Diego de Royas and Philip Gutierez were sent with above three hundred men to the eastwards, where they afterwards made some establishments on the Rio de la Plata.  Captain Monroy was sent to Chili with reinforcements to Pedro de Valdivia, who was engaged in reducing that country.  Captain Juan Perez de Guevara was sent to reduce the country of Mullobamba which he had discovered.  This is an exceedingly mountainous country, in which the two great rivers Marannon and La Plata have their sources, both of which run into the Atlantic.  Its inhabitants are Caribs, or canibals, and their country so hot that they go entirely naked, or at least have only a few rags round their loins.  While in this country, Juan Perez got notice of an extensive province beyond the mountains towards the north, in which there are rich gold mines, and which has camels and fowls like those of New Spain, and a species of sheep considerably smaller than those of Peru.  In that country it is necessary to water all kinds of seeds regularly, as it seldom rains.  In it there is a lake, the environs of which are exceedingly populous.  In all its rivers there are certain fishes as large as dogs, which they likewise very much resemble, which kill and eat the Indians when they go into the water or even pass near it, as they often come out of the water and walk on the dry land[15].  This great country is bounded on the north by the Marannon, on the east by Brasil, and on the south by the Rio de la Plata; and it is said that the Amazons dwell in this country, of whom Orellana received intelligence while descending the Marannon.
