[6] Still, or possibly even because he knew him that well after having lived for four years at his court, Louis XI resented the ambitions of Philip, who relentlessly expanded his duchy [7][8] and behaved like a king in his own right.

Louis XI was backed up by Gaston IV, Count of Foix, the big cities, and all provinces (like Languedoc, Normandy, Champagne, Dauphiné, and others).

He put the defence of this border into the hands of Joachim Rouault, sent Charles, Count of Maine (his uncle) with twelve thousand soldiers against the ruler of Brittany and took the rest of his army (including the Scottish Guard) in April against the Bourbons.

After he had conquered Moulins the Duke of Bourbon and other members of the League of the Public Weal signed a peace treaty on the King's terms.

Eventually he and his uncle, the comte du Maine, attacked Brittany's army from two sides and successfully hindered it from fusing with the Burgundians.

Pierre de Brézé managed to break through the lines and in the course of the subsequent disorder Louis XI in his turn attacked the heart of the enemy army.

Eventually, Brittany's army and other members of the League of the Public Weal rejoined the Burgundian forces and together besieged the French capital (from August 19th 1465).
