During these indications of tumult and rebellion, the viceroy Don Antonio de Mendoza died, to the great grief and detriment of the kingdom. On his death, the entire government of the kingdom of Peru devolved on the judges of the royal audience, who appointed Gil Ramirez de Avalos, who had been one of the gentlemen of the household to the viceroy, governor of the city of Lima; and the marshal was sent to command in the new city of La Paz, in which neighbourhood his lands and Indians were situated.
Narrative of the Troubles in Peru, consequent upon the Death of the Viceroy Mendoza..
At this threatening period, all the soldiers and discontented persons of Peru, flocked to Las Charcas, Potosi, and that neighbourhood, endeavouring to procure employment about the rich mines of that district. Disputes continually arose between the soldiers and principal inhabitants and merchants, and duels were fought almost daily. In some of these duels, the combatants fought naked from the waist upwards, while in others they were dressed in crimson taffety waistcoats, that they might not see their own blood. I shall only mention the particulars of one of these duels, between two famous soldiers, Pero Nunnez, and Balthazar Perez, with the former of whom I was acquainted in 1563 at Madrid, who was then so much disabled in both arms by the wounds he received in that duel, that he could scarcely use his hands to feed himself.
