The catastrophe was now at hand. The captains sent Borgia word that they had taken Sinigaglia, but that the fortress still held out; nor would the castellan deliver the keys to any but the duke in person; and they advised him, therefore, to come to receive them. Thus invited by the captains themselves, Borgia thought it an excellent opportunity to approach them without exciting suspicion. With great art he persuaded Vitelli and Paolo Orsino to wait for him at Sinigaglia, saying that their suspicion and timidity would render their reconciliation unstable and short-lived. Vitellozzo felt how unsafe it was, first to injure a prince, and then to put trust in him: but he was over-persuaded to remain by Orsino, whom the duke had corrupted by promises and gifts. Borgia left Fano on the 30th of December, and on the following day repaired to Sinigaglia; and on the evening of the last day of that month. Machiavelli wrote a short note to his government from that town, containing these words only:--"I wrote, the day before yesterday, from Pesaro, all I had heard concerning Sinigaglia.[118] I removed yesterday to Fano. Early this morning, the duke departed with all his troops, and came here to Sinigaglia, where were assembled all the Orsini and Vitellozzo, who had taken the town for him. He invited them to come around him; and, the moment he entered the town, he turned to his guard, and caused them to be taken prisoners. Thus he has secured them all, and the town is being pillaged. It is now twenty-three o'clock.[119] I am in the greatest anxiety, not knowing how to forward this letter, as there is no one to take it. I will write at length in another. In my opinion, they will not be alive to-morrow. All their people are also taken; and the official notice distributed about, says that the traitors are arrested."
