Cantelupe of Aston Cantlow; it was this association which led him to later side with the Barons. Peter de Montfort became the most powerful of all the de Montforts and in him the family was at the height of its glory. Peter obtained on, 10 February 1227 the grant of a market on Monday and a yearly fair at his manor of Beaudesert to be held on 'the eve, feast, and morrow of St. Giles'. In the Second Barons' War he sided against the king, Henry III and was one of those who formulated the Provisions of Oxford in 1258. He was taken prisoner at Northampton, but was released and following the Peace of Canterbury was elected one of the council of nine. He was killed fighting beside his kinsman Simon de Montfort, although the exact relationship is not known, at the Battle of Evesham in 1265. His eldest son Peter was taken prisoner at Evesham and placed in the custody of Thomas de Clare, to whom his forfeited lands were granted, but shortly afterwards he was pardoned and his lands restored to him. The manor then descended to his son John and then to his son, John who was aged 5 at his father's death, in 1296, and named as heir to the castle of Beaudesert. This John was concerned in the execution of Piers Gaveston, but was afterwards pardoned and died fighting for Edward II at the Battle of Bannockburn in 1314. As John left no issue, Beaudesert and Henley in Arden passed to Peter his brother who had one son named Guy, married to Margaret, daughter of Thomas de Beauchamp, Earl of Warwick. In 1349, the manor and castle of Beaudesert and the manor of Henley were settled on Guy with contingent reversion to the Earl of Warwick. Guy died in 1361, before his father, without issue, so after Peter de Montfort's death the manors reverted to the Earl of Warwick, who died in 1369. His son Thomas granted the manors to his brother William de Beauchamp for life in 1376. At his death in 1410 they were divided between William Boteler of Sudeley Castle and Baldwin Freville, son of Sir Baldwin Freville, who were descended from sisters of the last Peter de Montfort.
