 The Armagnac and Burgundian factions of the French court began negotiations to unite against the foreign enemy.Notable leaders of the Armagnac faction, such as Charles, Duke of Orléans, John I, Duke of Bourbon, and Arthur de Richemont (brother of the Duke of Brittany), became prisoners in England.The Burgundians, under John the Fearless, Duke of Burgundy, had conserved their forces, not having fought at Agincourt, but the duke's younger brothers—Anthony, Duke of Brabant and Philip II, Count of Nevers—died at that battle.
