This desertion drove Jean de Ville and his followers to despair. They made a night march to Tongres, surprised the Bishop's guards, some of whom they killed, and persuaded, or, rather, compelled, Louis and the Pope's legate to come with them to Liége. The war on which the insurgents counted when they thus captured the Bishop did not break out. On the contrary, negotiations had commenced, and ambassadors from France were discussing terms of peace with Charles at the very time of the raid on Tongres. The summer of 1468 was a time of splendour at the Court of Burgundy. On June 25 Margaret of York, attended by a brilliant company of English lords and ladies, sailed into the harbour of Sluis, where she was met by Charles the Bold. A week later they journeyed by the canal to the ancient town of Damme, where their marriage was celebrated at five o'clock on the morning of July 3. On that same day they entered Bruges in state, followed by a train of sixty ladies of the greatest families of England and Burgundy, and surrounded by nobles and princes who wore the Order of the Golden Fleece. The famous tournament of the Tree of Gold was held, after the marriage feast, in the market-place, and the revels continued for eight days longer. All was bright and gay in Flanders; but far away among the Ardennes dark clouds were gathering over the Valley of the Meuse. In the beginning of October the headquarters of the Burgundian army were at Peronne on the Somme. Louis XI. went thither with only a small escort, and sought an interview with Charles. Whatever his motive may have been for putting himself in the power of his rival, he had soon good reason to repent of his rashness. A party of Burgundians from Liége arrived at Peronne, accused the rebels of gross cruelty to the Bishop and to the Duke's friends, and asserted that some Frenchmen had taken part in the affair at Tongres. Charles, on hearing their statements, burst into one of his fits of uncontrollable anger. 'I know,' he cried, 'who is at the bottom of all this,' and forthwith locked up the King of France in the citadel of Peronne. After three days, during which Louis went in fear of his life, and Charles meditated all sorts of vengeance, the King was set free, and swore a solemn oath that he would assist Charles to punish the Liégeois. Then the allied forces of France and Burgundy marched into the Principality. When they approached Liége the Bishop and the papal legate met them, and endeavoured to make terms for the people, throwing themselves on their knees before Charles, and beseeching him not to punish the innocent and the guilty alike. The Bishop, it was pointed out, had pardoned the affront which he had received; but the Duke forbade them to speak of pardon. He was master, he said, of the lives and property of these incorrigible rebels, and he would do with them as he pleased. After this there was nothing more to be said. The doom of Liége had been spoken.
