He pulled down the walls and filled up the moat, until nothing remained so much as to show the place where the fortress had stood.
Another fortress which shared the fate of Castel Bolognese was the Castle of Sant' Arcangelo, and similarly would Cesare have disposed of Solarolo, but that, being of lesser importance and the inhabitants offering, in their petition for its preservation, to undertake, themselves, the payment of the Castellan, he allowed it to remain.
Scarcely was the treaty with Bologna signed than Cesare received letters from the Pope recalling him to Rome, and recommending that he should not molest the Florentines in his passage--a recommendation which Alexander deemed very necessary considering the disposition towards Florence of Vitelli and Orsini.

He foresaw that they would employ arguments to induce Valentinois into an enterprise of which all the cost would be his, and all the possible profit their own.
The duke would certainly have obeyed and avoided Tuscany, but that--precisely as the shrewd Pope had feared--Vitelli and Orsini implored him to march through Florentine territory.

Vitelli, indeed, flung himself on his knees before Cesare in the vehemence of his supplications, urging that his only motive was to effect the deliverance from his unjust imprisonment of Cerbone, who had been his executed brother's chancellor.

Beyond that, he swore he would make no demands upon Florence, that he would not attempt to mix himself in the affairs of the Medici, and that he would do no violence to town or country.
Thus implored, Cesare gave way.

Probably he remembered the very circumstances under which Vitelli had joined his banner, and considered that he could not now oppose a request backed by a promise of so much moderation; so on May 7 he sent his envoys to the Signory to crave leave of passage for his troops through Florentine territory.
Whilst still in the Bolognese he was sought out by Giuliano de'Medici, who begged to be allowed to accompany him, a request which Cesare instantly refused, as being contrary to that to which he had engaged himself, and he caused Giuliano to fall behind at Lojano.
