He fought for Edward at Bannockburn (1314). By 1318 he had organized a moderate royalist group of barons, which mediated successfully between the king and the rebellious barons until displaced (1322) by Hugh le Despenser, the elder, and his son. Pembroke died suddenly on a diplomatic mission to France.
