He declared to him that he desired a good understanding with Florence, and that she should offer no hindrance to the conquest of Piombino, upon which he was now bound; adding that since he placed no trust in the present government, which already had broken faith with him, he would require some good security for the treaty to be made.

Of reinstating the Medici he said nothing; but he demanded that some satisfaction be given Vitelli and Orsini, and, to quicken Florence in coming to a decision, he pushed forward with his army as far as Forno dei Campi--almost under her very walls.
The Republic was thrown into consternation.

Instantly she got together what forces she disposed of, and proceeded to fling her artillery into the Arno, to the end that she should be constrained neither to refuse it to Cesare upon his demand, nor yet to deliver it.
Macchiavelli censures the Signory's conduct of this affair as impolitic.
He contends that the duke, being in great strength of arms, and Florence not armed at all, and therefore in no case to hinder his passage, it would have been wiser and the Signory would better have saved its face and dignity, had it accorded Cesare the permission to pass which he demanded, rather than have been subjected to behold him enforce that passage by weight of arms.

But all that now concerned the Florentines was to be rid of an army whose presence in their territory was a constant menace.

And to gain that end they were ready to give any undertakings, just as they were resolved to fulfil none.
Similarly, it chanced that Cesare was in no less a hurry to be gone; for he had received another letter from the Pope commanding his withdrawal, and in addition, he was being plagued by Vitelli and Orsini--grown restive--with entreaties for permission to go into either Florence or Pistoja, where they did not lack for friends.
