 With violent disorder spreading and the prospect of all-out war, Henry appealed to Louis for arbitration, and after initial resistance de Montfort consented to this.In January 1264, by the Mise of Amiens, Louis declared in Henry's favour, annulling the Provisions of Oxford.Some of the barons who had previously opposed Henry acquiesced in this verdict, but a more radical faction led by de Montfort prepared to resist any reassertion of royal power, and both they and the king gathered their forces for war.
