The Battle

History & Significance

After Evesham, Gilbert de Clare broke with the royalist cause in 1267 and seized Gloucester to enforce better terms for the disinherited barons. This action forced Henry III to negotiate the Dictum of Kenilworth and brought an end to the post-Evesham period of punitive royalism. Gloucester was again a pivot of Severn valley control as it had been in the earlier campaign.
