King of England, if you do not do these things, I am the commander of the military; and in whatever place I shall find your men in France, I will make them flee the country, whether they wish to or not; and if they will not obey, the Maid will have them all killed. She comes sent by the King of Heaven, body for body, to take you out of France, and the Maid promises and certifies to you that if you do not leave France she and her troops will raise a mighty outcry as has not been heard in France in a thousand years. And believe that the King of Heaven has sent her so much power that you will not be able to harm her or her brave army.
