トロワ条約
The English regent, the Duke of Bedford, was anxious to preserve the claim of his nephew and charge Henry VI of England, grandson of Charles VI and nephew of Charles VII, to the throne of France, as per the Treaty of Troyes. Cauchon escorted Henry from London to Rouen as part of a clerical delegation. Shortly after he returned, he learned that Joan of Arc had been taken captive near Compiègne. The Burgundians held her at the keep of Beaulieu near Saint-Quentin.
