Richard Marshal held lands in Longueville, Normandy; in Wales; and also in Ireland. portrayed by Matthew Paris as unhorsing Baldwin of Guines at a skirmish before the Battle of Monmouth in 1233. He came to the fore as the leader of the baronial party, and the chief antagonist of the foreign friends of King Henry III of England, a notable Poitevin, Peter des Roches, Bishop of Winchester and Peter de Rivaux. Fearing their treachery, he refused to visit King Henry III at Gloucester in August 1233, and he was declared a traitor. According to the chronicler Roger of Wendover in his Flores Historiarum, Marshal and his knights then came to Monmouth to reconnoitre the town before besieging it. However, they were seen coming towards the castlewalls by Baldwin III, Count of Guînes. He was a nobleman of Flanders who, with his mixed force of Flemings and Poitevins, had been entrusted by King Henry with defending the town. The local lord, John of Monmouth, was absent from the battle. Baldwin wrongly thought that Marshal had only a few followers with him, and rode out with his forces to pursue him, but Marshal turned the tables. It was said of Marshal that he put up a gallant defense against Baldwin's men in this skirmish and his army defeated Baldwin's forces at the Battle of Monmouth on 25 November. In March 1234, a truce was reached between the king and Marshal, the condition of which was the removal of Peter de Rivaux from court. In the meanwhile, however, conflict had broken out in Ireland between Marshal's brothers and some of the king's supporters. Hostilities followed, and Richard made an alliance with the Welsh prince Llywelyn the Great. Pembroke crossed from Wales to Ireland, where Peter des Roches had allegedly instigated his enemies to attack. In April 1234 he was overpowered and wounded at the Battle of the Curragh by forces led by Maurice FitzGerald, Justiciar of Ireland and died of his wounds on 16 April 1234 while being held prisoner. Marshal's popularity also meant that his death was mourned in England, while the Poitevinswho were rumoured to have instigated the Irish warfell further into disregard. He had married Gervaise de Dinan, daughter of Alan de Dinan, Baron de Dinan, and did not produce any offspring. He was buried at Kilkenny and was succeeded by his brother Gilbert.
