They fell out respecting some circumstances of a duel that had happened a few days before, in which they were seconds. Balthazar Perez had Egas de Guzman for his second, one of the greatest hectors and bullies of the time; and Hernan Mexia prevailed on Pero Nunnez to take him for his second, that he might have an opportunity to fight Guzman, who had defamed and spoken lightly of Mexia. When Egas de Guzman understood that Mexia was the person who was to be opposed to him, he sent a message to Pero Nunnez saying, as the principals were gentlemen of family, he ought not to debase himself by having a man for his second whose mother was a Morisca and sold broiled sardinas in the market of Seville. Pero Nunnez, knowing this to be true, endeavoured to get Mexia to release his promise, but could not prevail. They accordingly went out to fight in a field at some distance from Potosi. At the first rencounter of the principals, Pero Nunnez struck his adversaries sword to one side, and closing upon Perez threw him to the ground, where he cast dust into his eyes, and beat him about the face with his fists, but did not stab him with his dagger. In the mean time the seconds were engaged in another part of the field. Mexia was afraid to close with Guzman, knowing him to have great bodily strength, but kept him in play by his superior agility, leaping and skipping about, yet never coming near enough to wound him. At length, wearied with this mode of fighting, Guzman darted his sword at Mexia, who looking anxiously to avoid it, gave an opportunity to Guzman to close with him, and to give him a wound with his dagger in the skull, two fingers deep, where the point of the dagger broke off; Mexia became frantic with his wound, and ran about the field like a madman; and came up to where the two principals were struggling on the ground, where, not minding whom he struck, he gave his own principal a slash with his sword, and ran wildly away. Guzman came hastily up to the rescue of his own principal, when he heard Nunnez say that he had been wounded by his own second, and was still continuing to pummel Perez on the face, and to throw dust in his eyes. Then Guzman, after harshly reproving Nunnez from bringing such a rascal to the field as his second, attacked Nunnez with his sword, who defended himself as he best could with his arms, till he was left all hacked and hewed on the field, streaming with blood from many wounds. Guzman then helped up his companion, and taking all the four swords under his arm, took Perez on his back who was unable to stand, and carried him to an hospital where he desired them to bury him, after which he took sanctuary in a church. Nunnez was likewise taken to the hospital, where he recovered of his wounds, but Mexia died of the wound in his forehead, as the point of the dagger could not be extracted from his skull.
