Giampolo was, still living in Sardinia, more than all other Corsican patriots a source of continual anxiety to the Genoese, who made several attempts to come to an amicable agreement with him. His son Orlando, who had newly escaped to Rome from his prison in Genoa, sent pressing solicitations from that city to his father to rouse himself from his dumb and prostrate inactivity. But Giampolo continued to maintain his heartbroken silence, and listened as little to the suggestions of his son as to those of the Genoese. Suddenly Renuccio disappeared from Genoa in the year 1504; he left wife and child in the hands of his enemies, and went secretly to Sardinia to seek an interview with the man whom he had plunged into misfortune. Giampolo refused to see him. He was equally deaf to the entreaties of the Corsicans, who all eagerly awaited his arrival. His own relations had in the meantime murdered his son. The viceroy caught the murderers, and was about to execute them, in order to show a favour to Giampolo. But the generous man forgave them, and begged their liberation. Renuccio had meanwhile gathered eighteen resolute men about him, and, undeterred by the fate of his children, who had been thrown into a dungeon immediately after his flight, he landed again in Corsica. Nicolas Doria, however, lost no time in attacking him before the insurrection became formidable, and he gained a victory. To daunt Renuccio, he had his eldest son beheaded, and he threatened the youngest with a like fate, but allowed himself to be moved by the boy's entreaties and tears. The unhappy father, defeated at every point, fled to Sardinia, and then to Arragon. Doria took ample revenge on all who had shown him countenance, laid whole districts of the island waste, burned the villages, and dispersed the inhabitants. Renuccio della Rocca returned in the year 1507. This unyielding man was entirely the reverse of the moody and sorrow-laden Giampolo. He set foot on his native soil with only twenty companions. Another of the Dorias met him this time, Andreas, afterwards the famous Doge, who had served under his cousin Nicolò. The Corsican historian Filippini, a Genoese partisan, admits the cruelties committed by Andreas during this short campaign. He succeeded in speedily crushing the revolt; and compelled Renuccio a second time to accept a safe conduct to Genoa. When the Corsican arrived, the people would have torn him to pieces, had not the French governor carried him off with all speed to his castle.
