As Louis never sacrificed his interest to his passion, so Charles, on the other hand, never sacrificed his passion, or even his humour, to any other consideration.

Notwithstanding the near relationship that existed between them, and the support which the Duke and his father had afforded to Louis in his exile when Dauphin, there was mutual contempt and hatred betwixt them.

The Duke of Burgundy despised the cautious policy of the King, and imputed to the faintness of his courage that he sought by leagues, purchases, and other indirect means those advantages which, in his place, the Duke would have snatched with an armed hand.

He likewise hated the King, not only for the ingratitude he had manifested for former kindnesses, and for personal injuries and imputations which the ambassadors of Louis had cast upon him, when his father was yet alive, but also, and especially, because of the support which he afforded in secret to the discontented citizens of Ghent, Liege, and other great towns in Flanders.

These turbulent cities, jealous of their privileges, and proud of their wealth, were frequently in a state of insurrection against their liege lords, the Dukes of Burgundy, and never failed to find underhand countenance at the court of Louis, who embraced every opportunity of fomenting disturbance within the dominions of his overgrown vassal.
The contempt and hatred of the Duke were retaliated by Louis with equal energy, though he used a thicker veil to conceal his sentiments.
