Jeanne D'Arc was from the Duchy of Lot, which did become a part of France for another couple hundred years--The voices told her to go to France, and, being divine in origin, they knew their geography pretty well--She is called the "Maid of Orleans" because she raised the siege--

... This voice told me, two or three times a
         week, that I must go away and that I must come
         to France; and my father knew nothing of my
         leaving. The voice told me that I should go to
         France and I could no longer stay where I was.
         It told me that I should raise the siege laid
         to the city of Orléans. The voice told me also
         that I should go to Robert de Baudricourt at
         the town of Vaucouleurs, who was the captain
         of the town, and he would provide people to go
         with me. And I replied that I was a poor girl
         who knew neither how to ride4 nor lead in
         war."5
