King Philip of France and the Duke of Austria, on behalf of Arthur, begin to lay siege to the city of Angiers, property of the English monarch. John and his army arrive. Each king demands that the citizens of Angiers allow the “King of England” to enter, but the citizens ask for proof as to which (John or Arthur) is the true king. When the kings decide to join forces to destroy the city, the citizens propose that the kings instead become allies through a marriage of the French Dauphin Louis to John’s niece Blanche. To further this proposed alliance, John gives up five Continental provinces and makes Arthur Duke of Brittany and Earl of Richmond, while Philip abandons Arthur’s cause.
