Life had been as yet but a dream for Charles and his queen; though France was rapidly going to ruin under their extravagant and heedless rule, could they not chase away care in revels surpassing any that France had yet seen? But the dream was soon to become a nightmare, the hideous nightmare of insanity, for this heedless monarch. It was not until three years after the coronation of Isabeau that her unfortunate husband had the first attack of what was, unmistakably, insanity, though to any reasonable creature the behavior of the whole court would have seemed mad enough from the beginning. One of those acts of lawless private vengeance which were so soon to become dreadfully familiar in France first excited the king almost to the point of frenzy. A certain Pierre de Craon, a noble who had already distinguished himself by robbing the late Duke of Anjou, was driven from Paris by the Duke of Orléans, to whose wife he had imprudently revealed some of the infidelities of her too licentious husband. He fled to Jean de Montfort, who persuaded him that the person chiefly responsible for his disgrace was the renowned Olivier de Clisson, Conétable of France. Secretly returning to Paris, Pierre de Craon lay in wait for the constable one night and fell upon him with a band of bravoes. The brave De Clisson was seriously wounded, and the villains fled, thinking him slain. Charles, who favored De Clisson, was furious at the outrage, and breathed vengeance against Craon. As Jean de Montfort constituted himself the defender of this wretch, and refused to deliver him up to justice, the lands belonging to Craon were devastated, his wife and children were driven forth, and war was declared upon Brittany.
