The Battle

History & Significance

William de Forz, Count of Aumale, was a turbulent magnate who resisted the restoration of royal authority after the First Barons War. Bytham Castle in Lincolnshire was his stronghold. The regent William Marshal besieged and captured it in 1221 as part of the systematic reassertion of royal control over castellans who had profited from the civil war. De Forz submitted.
