Richard Marshal's withdrawal marks the end of the coalition which since August 1232 had dominated the court. First the household establishment had been neutralized by the attacks against Mauclerk and Crowcombe, and then the Marshal had been edged out. This left des Roches and his men alone but dangerously isolated at the centre of power. For the moment they were able to celebrate their new-found supremacy in a flurry of awards and promotions. By the end of March 1233 Peter de Rivallis had acquired personal interests in three Kent manors formerly part of de Burgh's private estate. On 28 February his life interest in Pevensey castle was transformed into a hereditary award in fee. The death of William Brewer that spring brought de Rivallis even greater custodies as the king's keeper of escheats, pending settlement amongst Brewer's heirs. Meanwhile the royal castle of Bridgwater, recovered from Brewer, passed to Peter de Russelis, a Somerset man and former protégé of Peter de Maulay, for whom also a Norman manor in Dorset was seized back from its former custodian in what looks suspiciously like another disseisin per voluntatem regis. Amongst de Burgh's estates, various long-term interests were conferred upon the Domus Dei Portsmouth, a hospital under des Roches' patronage. Yet another of de Burgh's former manors passed to Anketil Malory, a kinsman of Stephen of Seagrave. By June 1233 Malory's tenancy there had been transformed into one in perpetual fee. Seagrave himself was made hereditary lord of the manor of Melbourne. For Brian de Lisle there were market privileges, and in April 1233 a grant of the sheriffdom of Yorkshire for life.
