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.
Contemporary chroniclers identify some of those who fought at Lewes; the names of others appear in legal documents. The presence of many more can be deduced from circumstantial evidence....The Earl of Leicester was Sir Waleran’s landlord. Of course, a knight does not pay rent - he turns up when required, with his horse and harness and his retinue, and fights for his lord. Sir Waleran must have been called up: Simon needed all the help he could get, and was at Herstmonceux a few days before the battle. And Waleran must have honoured his pledge: next year he is a trusted bodyguard to Countess Eleanor as she runs for the safety of Dover Castle.
