[1] Charles of Orléans, son of the murdered Louis, married Bonne d'Armagnac, daughter of Bernard VII, count of Armagnac.
The following month he presented a long document known as The Justification of the Duke of Burgundy containing proof of the Armagnac schemes of intrigue.
It largely failed because as the Armagnacs laid siege to Paris, a small English force landed at Calais to assist the Burgundian government.
[1] Thomas, Duke of Clarence, a fiery cavalry general, demanded considerable territorial concessions including Normandy in return for aid to Burgundy.
Now desperate to save the honour of the Oriflamme, the Armagnacs resorted to seeking English arbitration in the internal dispute.
In a series of humiliating encounters their leading general, Louis, Duke of Guyenne (then the Dauphin), was outmanoeuvred, defeated, and forced into the Treaty of Auxerre.
However, in a meeting on the bridge at Montereau in September 1419, followers of the Dauphin Charles (who had succeeded in 1417) assassinated John the Fearless.
The terms remained in use until they were outlawed by Charles VII toward the close of the Hundred Years' War, as part of efforts to heal the factional rift.
