 Joan was imprisoned by the Burgundians at Beaurevoir Castle.She made several escape attempts, on one occasion jumping from her 70-foot (21 m) tower, landing on the soft earth of a dry moat, after which she was moved to the Burgundian town of Arras.The English negotiated with their Burgundian allies to transfer her to their custody, with Bishop Pierre Cauchon of Beauvais, an English partisan, assuming a prominent role in these negotiations and her later trial.
