As he had fulfilled all his promises, except the matter of the loan, which could not be settled anywhere but at Florence, the king saw no objection, and the very evening after he quitted the French army Piero returned incognito to his palace in the Via Largo.
The next day he proposed to present himself before the Signoria, but when he arrived at the Piazza del Palazzo Vecchio, he perceived the gonfaloniere Jacopo de Nerli coming towards him, signalling to him that it was useless to attempt to go farther, and pointing out to him the figure of Luca Corsini standing at the gate, sword in hand: behind him stood guards, ordered, if need-were, to dispute his passage.

Piero dei Medici, amazed by an opposition that he was experiencing for the first time in his life, did not attempt resistance.

He went home, and wrote to his brother-in-law, Paolo Orsini, to come and help him with his gendarmes.

Unluckily for him, his letter was intercepted.

The Signoria considered that it was an attempt at rebellion.
