Page "Battle of Lewes" Paragraph 4

The King was forced to sign the so-called Mise of Lewes.

Though the document has not survived, it is clear that Henry was forced to accept the Provisions of Oxford, while Prince Edward remained hostage to the barons.

This put Montfort in a position of ultimate power, which would last until Prince Edward's escape, and Montfort's subsequent defeat at the Battle of Evesham in August 1265.
