During Simon de Montfort's barons war, March 31, 1264 Londoners riot (London was very pro de Montfort), burn townhouses of the hated William de Lusignan, also prominent Royalist Lord Philip Basset, also Richard of Cornwall's Westminster manor, & his beloved Isleworth manor 7 miles away. Richard overnight goes from trying to mediate a solution to, like Edward, ardently desiring a battlefield confrontation. Richard was not popular with his brother Henry III's subjects as he was intelligent, pragmatic, had business acumen, & a lack of rancor; these qualities were disdained in favor of reckless courage, battlefield prowess, & open-handed generosity, which was expected of Lords. Richard's courage was never suspect; but he was not an innovative nor brilliant military commander. At Battle of Lewes on 14 May 1264, Richard commanded the left flank of the Royalist forces. After Prince Edward left the battle to pursue with unwholesome savagery the rebel Londoner flank of Montfort's forces, Montfort, keeping a reserve force (a tactic unheard of) came in & attacked Henry & obliterated his force; Henry fleed to the priory. Gilbert de Clare's center column forces met Richard's & took the day. Richard with his son Edmund fled into a windmill. When de Clare's forces captured the, they jeered "come out king of the millers". John Giffard's squire was the one who officially accepted Richard's royal surrender, adding to Richard's discomposure (that he had surrendered to a squire rather than a knight). Upon his presentation to Simon de Montfort, Simon made the lad, John Befs of Tewkesbury, a knight.
