At a young age she began to hear voices—those of St. Michael, St. Catherine, and St. Margaret. When she was about 16, the voices exhorted her to bear aid to the dauphin, later King Charles VII, then kept from the throne by the English in the Hundred Years War. Joan won the aid of Robert de Baudricourt, captain of the dauphin's forces in Vaucouleurs, in obtaining an interview with the dauphin. She made the journey in male attire, with six companions. Meeting the dauphin at Chinon castle, she conquered his skepticism as to her divine mission. She was examined by theologians at Poitiers, and afterward she was furnished with troops by Charles.

Her leadership provided spirit and morale more than military prowess. In May, 1429, she succeeded in raising the siege of Orléans, and in June she took other English posts on the Loire and defeated the English at Patay. After considerable persuasion the dauphin agreed to be crowned at Reims; Joan stood near him at his coronation. This was the pinnacle of her fortunes.

In Sept., 1429, Joan unsuccessfully besieged Paris. The following spring she went to relieve Compiègne, but she was captured by the Burgundians and sold to the English, who were eager to destroy her influence by putting her to death. Charles VII made no attempt to secure her freedom. In order to escape responsibility, the English turned her over to the ecclesiastical court at Rouen. She was tried for heresy and witchcraft before Pierre Cauchon and other French clerics who supported the English.

Probably her most serious crime was the claim of direct inspiration from God; in the eyes of the court this refusal to accept the church hierarchy constituted heresy. Throughout the lengthy trial and imprisonment she bravely fought her inquisitors. Only at the end of the trial, when Joan was sentenced to be turned over to a secular court, did she recant. She was condemned to life imprisonment. Shortly afterward, however, she retracted her abjuration, was turned over to the secular court as a relapsed heretic, and was burned at the stake (May 30, 1431) in Rouen. Charles VII made tardy recognition of her services by a rehabilitation trial in 1456 that annulled the proceedings of the original trial.

Joan was beatified in 1909 and canonized in 1920 (feast: May 30). Her career lent itself to numerous legends, and she has been represented in many paintings and statues. In literature and music she appears notably, though not always accurately, in works by many eminent writers and composers.
