While these deliberations were going on in Lima, Gonzalo Pizarro drew nigh with his army and encamped about a quarter of a league from the city, drawing up his numerous train of artillery in readiness for service. As a whole day elapsed without the formal appointment as governor being transmitted to him, he became impatient; and dispatched thirty musqueteers into the city under the command of his lieutenant-general, who made prisoners of twenty-eight persons, among whom were those who had formerly deserted him at Cuzco, and others who were most obnoxious for having taken part with the viceroy. Among these were Gabriel de Roias, Garcilasso de la Vega, Melchior Verdugo, the licentiate Carvajal, Pedro de Barco, Martin de Florencia, Alfonso de Caceres, Pedro de Manjares, Luis de Leon, Antonio Ruys de Guevara, and some others of highest consideration in the colony. These were committed to the common prison, of which the lieutenant-general took possession, taking away the keys from the alcalde or keeper. The judges were utterly unable to make the smallest opposition to this strong measure, and dared not even to express their disapprobation, as there did not now remain fifty soldiers in the city; all those who had been formerly attached to them or to the viceroy having gone over to the camp of Gonzalo, who had now a force of twelve hundred men completely armed, including his original troops and those who deserted to him on this occasion.
Next morning, several of the insurgent officers came into the city, and required the judges to make out the commission for Gonzalo, and to proclaim him governor-general of Peru without delay, otherways threatening to give up the city to plunder, and to massacre the inhabitants, in which case they would begin by putting the judges to death. The judges endeavoured to excuse themselves, alleging that they had neither right nor authority to do what was desired. Whereupon Carvajal, the lieutenant-general under Pizarro, caused four of his prisoners to be brought from the prison, and ordered three of them to be hanged on a tree near the city. These unfortunate men were Pedro de Barco, Martin de Florencia, and Juan de Saavedra. Carvajal only allowed them a short half hour to confess their sins and to prepare for death, adding insult and mockery to his cruelty. He particularly indulged in raillery against Pedro de Barco, who was last executed; saying, as he was a brave commander who had made several conquests, and was one of the most considerable and richest men in Peru, he was inclined to allow him some distinction in his death, and that he therefore granted him the high and honourable privilege of choosing which branch of the tree he preferred for being hanged upon. Luis de Leon escaped at the intercession of his brother who served under Gonzalo.
