Joan of Arc dictates warning to the English

In her attempt to convince the Dauphin of the sincerity of her mission, Joan submitted to examinations by eminent ecclesiastical advisors to Charles. She told them that she would give proof of her mission at Orléans and dictated a letter of warning to the English king and his troops. The theologians suggested the Dauphin should make use of her, and he provided her several men and sent her on to Orléans, where the siege was soon raised.
