Piero found it no harder to dispose of money than of fortresses, and replied that his fellow-citizens would be happy to render this service to their new ally.

Then Charles VIII set him on horseback, and ordered him to go on in front, so as to begin to carry out his promises by yielding up the four fortresses he had insisted on having.

Piero obeyed, and the French army, led by the grandson of Cosimo the Great and the son of Lorenzo the Magnificent, continued its triumphal march through Tuscany.
On his arrival at Lucca, Piero dei Medici learnt that his concessions to the King of France were making a terrible commotion at Florence.

The magnificent republic had supposed that what Charles VIII wanted was simply a passage through her territory, so when the news came there was a general feeling of discontent, which was augmented by the return of the other ambassadors, whom Piero had not even consulted when he took action as he did.

Piero considered it necessary that he should return, so he asked Charles's permission to precede him to the capital.
