By 1428, 20-year-old Antoine de Chabannes fought alongside Joan of Arc in battles including Jargeau, Patay (where he led the vanguard and was wounded), and the Siege of Compiègne where Joan was captured in May 1430. In the meantime he had participated in the March to Reims and attended the epic coronation ("sacre") of Charles VII, on 17 July 1429.
