In 1468, Louis and Charles met at Péronne, but during the course of negotiations, they learned that the citizens of Liège had again risen up against Charles and killed the Burgundian governor. Charles was furious. Philippe de Commines, at that time in the service of the duke of Burgundy, had to calm him down with the help of the duke's other advisors for fear that he might hit the king. Louis was forced into a humiliating treaty. He gave up many of the lands he had acquired from Philip the Good, turned on his erstwhile allies in Liège and swore to help Charles put down the uprising in Liège. Louis then witnessed a siege of Liège in which hundreds were massacred.
