A plot was formed in favor of the fallen tyrant, who was in Germany expecting it, and was recruiting, during expectancy, amongst the Germans and Swiss in order to take advantage of it.

On the 25th of January, 1500, the insurrection broke out; and two months later Ludovic Sforza had once more become master of Milaness, where the French possessed nothing but the castle of Milan.

In one of the fights brought about by this sudden revolution the young Chevalier Bayard, carried away by the impetuosity of his age and courage, pursued right into Milan the foes he was driving before him, without noticing that his French comrades had left him; and he was taken prisoner in front of the very palace in which were the quarters of Ludovic Sforza.

The incident created some noise around the palace; Ludovic asked what it meant, and was informed that a brave and bold gentleman, younger than any of the others, had entered Milan pell-mell with the combatants he was pursuing, and had been taken prisoner by John Bernardino Casaccio, one of the leaders of the insurrection.

Ludovic ordered him to be brought up, which was done, though not without some disquietude on the part of Bayard's captor, "a courteous gentleman, who feared that Lord Ludovico might do him some displeasure." He resolved himself to be his conductor, after having dressed him in one of his own robes and made him look like a gentleman.
"Marvelling to see Bayard so young, 'Come hither, my gentleman,' said Ludovico: 'who brought you into the city ?' 'By my faith, my lord,' answered Bayard, who was not a whit abashed, 'I never imagined I was entering all alone, and thought surely I was being followed of my comrades, who knew more about war than I, for if they had done as I did they would, like me, be prisoners.
