The Battle

History & Significance

Bytham Castle in Lincolnshire was held by William de Forz, Count of Aumale, a turbulent magnate who resisted royal authority in the aftermath of the First Barons War. The regent William Marshal besieged it in 1221 as part of restoring royal control over unruly castellans. The castle fell and was slighted. De Forz submitted to the crown. The episode was part of the broader royal recovery of castles during the minority of Henry III.
