"In 1392, the King of France being seized with madness, the Dukes of Burgundy and Orleans in a very short time wrested the power of the state from the hands of his faithful councillors, the Constable de Clisson, La Riviere, and others. De Clisson retired to his estate and castle at Montelhery, the two others were seized and thrown into prison. De Clisson was prosecuted before Parliament as a false and wicked traitor; but the king, acting on the advice of Orleans, who had not then broken with the Dukes of Burgundy and Berri, had, after La Riviere and another had been in prison for a year, stopped the prosecution, and restored their estates to them. Until 1402 the Dukes of Burgundy and Berri were all-powerful, and in 1396 a great number of knights and nobles, led by John, Count of Nevers, the eldest son of the Duke of Burgundy, went to the assistance of the King of Hungary, which country was being invaded by the Turks. They were, however, on the 28th of September, utterly defeated. The greater portion of them were killed; Nevers and the rest were ransomed and brought home.
