Keen local historian Jon Gunson has compiled this series entitled Friday Knight - knights who fought at the Battle of Lewes - giving each a brief biography.
When Sir Henry was a minor, his estates seem to have been despoiled by Henry III’s French favourites, the Lusignans.
Certainly he felt no love or respect for the King. He was with de Clare at Rochester, was knighted before the Battle of Lewes by de Monfort, and was one of the commanders of the unfortunate division of Londoners on the baronial left wing. When the war was over, he joined the diehard rebels known as ‘The Disinherited’, and fought on from their stronghold near Ely. The chronicler Thomas Wyke (a royalist sympathiser) calls him “malefactorum maleficus gubernator” - “the criminal leader of a criminal gang”.
