If Guidobaldo did engage in such an act, amounting to a betrayal, he was certainly paid by Cesare in kind and with interest. If the duke had been short of a pretext for carrying a drawn sword into the dominions of Guidobaldo, he had that pretext now in this act of enmity against himself and the Holy See. First, however, he disposed for the attack upon Camerino. This State, lying on the Eastern spurs of the Apennines, midway between Spoleto and Urbino, was ruled by Giulio Cesare Varano, an old war-dog of seventy years of age, ruthless and bloodthirsty, who owed his throne to his murder of his own brother. He was aided in the government of his tyranny by his four sons, Venanzio, Annibale, Pietro, and Gianmaria. Several times already had he been menaced by Cesare Borgia, for he was one of the Vicars proscribed for the non-payment of tribute due to the Holy See, and at last his hour was come. Against him Cesare now dispatched an army under the command of Francesco Orsini, Duke of Gravina, and Oliverotto Eufreducci, another murderous, bloody gentleman who had hitherto served the duke in Vitelli’s condotta, and who, by an atrocious act of infamy and brigandage, had made himself Lord of Fermo, which he pretended--being as sly as he was bloody--to hold as Vicar for the Holy See. This Oliverotto Eufreducci--hereafter known as Oliverotto da Fermo--was a nephew of Giovanni Fogliano, Lord of Fermo. He had returned home to his uncle’s Court in the early part of that year, and was there received with great honour and affection by Fogliano and his other relatives. To celebrate his home-coming, Oliverotto invited his uncle and the principal citizens of Fermo to a banquet, and at table contrived to turn the conversation upon the Pope and the Duke of Valentinois; whereupon, saying that these were matters to be discussed more in private, he rose from table and begged them to withdraw with him into another room. All unsuspecting--what should old Fogliano suspect from one so loved and so deeply in his debt?--they followed him to the chamber where he had secretly posted a body of his men-at-arms. There, no sooner had the door closed upon this uncle, and those others who had shown him so much affection, than he gave the signal for the slaughter that had been concerted. His soldiers fell upon those poor, surprised victims of his greed, and made a speedy and bloody end of all. That first and chief step being taken, Oliverotto flung himself on his horse, and, gathering his men-at-arms about him, rode through Fermo on the business of butchering what other relatives and friends of Fogliano might remain. Among these were Raffaele della Rovere and two of his children, one of whom was inhumanly slaughtered in its mother’s lap.
