A few days later, on 10 August, Francis was forced to sign the Treaty of Verger. Under the terms of the treaty, the duke was compelled to submit himself and his duchy as a vassal of the king of France, and to expel foreign princes and troops from Brittany. It also restricted his ability to marry his children to suitors of his choosing and required that he cede territory in Saint-Malo, Fougères, Dinan, and Saint-Aubin to the king as a guarantee that in the absence of a male successor the king would determine the succession. Francis died a few months later as a result of a fall from his horse during a leisurely ride. He left only a daughter, Anne of Brittany, so the treaty was used to force her, as his successor, to marry Charles VIII, and later Louis XII. Despite the French victory and the signing of the treaty, la Guerre Folle dragged on beyond Francis II's death for three more years until December 1491, when Anne married Charles VIII.
