 In 1282 , war with Wales broke out again ; this time it would not be simply a punitive campaign , but a full @-@ scale war of conquest . Initially , the king wanted to fight the war with paid forces , but the nobility insisted on the use of the feudal summons . To men like Hereford , this was preferable , because as part of a feudal army the participants would have both a stake in the war and a justifiable claim on conquered land . In the end , although the earls won , none of them were paid for the war effort . Hereford jealously guarded his authority as hereditary Constable of England , and protested vigorously when the Gilbert de Clare , Earl of Gloucester was appointed commander of the forces in South Wales . In the post war settlement , however , neither Hereford nor Gloucester received any significant rewards of land , the way several other magnates did . Hereford fought again in Wales , in the suppression of the rebellion of 1294 – 95 , when he again had to pacify the territory of Brecon before joining the king in the north .
