On arriving in Moscow he found that the mutiny had been suppressed and the ringleaders punished, but he considered it necessary to reopen the investigation and act with exemplary severity.
He disgraced or imprisoned the ringleaders, ordered Bernadotte (perhaps the fountain head of the whole affair) to take the waters at Plombieres and drove from office Fouche, who had sought to screen the real offenders by impugning the royalists.
The doors were opened, the ringleaders were admitted and immediately seized and hanged.
But a promise of French help at once forced the confederates to come to terms, and Cesare by an act of treachery seized the ringleaders at Senigallia, and put Oliverotto da Fermo and Vitellozzo Vitelli to death (Dec. 31, 1502).
But the plot came to light; its chief ringleaders were beheaded, and many others sent into exile (1456); and the death of Alphonso at last ended all danger from that source.
