Battle of Castillon
The Dauphin was crowned as King Charles VII of France at Reims on 17 July 1429, largely through the martial efforts of Joan of Arc, who believed it was her mission to free France from the English and to have the Dauphin Charles crowned at Reims. In 1435, the Duke of Burgundy, released from his obligations to Henry VI by a papal legate, recognised Charles VII as the rightful king of France. The defection of this powerful French noble marked the decline of Henry's de facto reign over France. The dual monarchy came to an end with the capture of Bordeaux by Charles VII's forces on 19 October 1453 following their final victory at the Battle of Castillon (17 July 1453), thus bringing the Hundred Years' War to a conclusion. The English were expelled from all of the territories which they had controlled in France, with the sole exception of Calais. Charles VII had thus established himself as the undisputed king of almost all of France.
