At the same time, while Orsino was carrying to the confederates the treaty drawn up between him and the duke, Bentivoglio, not willing to submit to the arbitration indicated, made an offer to Caesar of settling their differences by a private treaty, and sent his son to arrange the conditions: after some parleying, they were settled as follows:— Bentivaglio should separate his fortunes from the Vitelli and Orsini; He should furnish the Duke of Valentinois with a hundred men-at-arms and a hundred mounted archers for eight years; He should pay 12,000 ducats per annum to Caesar, for the support of a hundred lances; In return for this, his son Hannibal was to marry the sister of the Archbishop of Enna, who was Caesar’s niece, and the pope was to recognise his sovereignty in Bologna; The King of France, the Duke of Ferrara, and the republic of Florence were to be the guarantors of this treaty. But the convention brought to the confederates by Orsino was the cause of great difficulties on their part. Vitellozza Vitelli in particular, who knew Caesar the best, never ceased to tell the other condottieri that so prompt and easy a peace must needs be the cover to some trap; but since Caesar had meanwhile collected a considerable army at Imola, and the four hundred lances lent him by Louis XII had arrived at last, Vitellozzo and Oliverotto decided to sign the treaty that Orsino brought, and to let the Duke of Urbino and the lord of Camerino know of it; they, seeing plainly that it was henceforth impossible to make a defence unaided, had retired, the one to Citta di Castello and the other into the kingdom of Naples.
