their own profit. Due to his role in the campaign and the victory at Lincoln itself he was unassailable for many years; he deflected judgements made against him in 1218 and 1219 and kept hold of his High Sheriffdoms, including that of Rutland. Between 1218 and 1219 he also served as a Justice of the Peace for Essex, Hertfordshire and East Anglia, and when William de Redvers, 5th Earl of Devon died he was given the castle of Plympton. He had made many enemies due to his actions during the war; numbered among them were William Marshal, who pawned four manors to him during the war and had difficulty getting them back, and the Earl of Salisbury, who grew to dislike him after de Bréauté supported Nicola de la Haie for constable of Lincoln Castle against Salisbury's personal preference. Due to his status as a commoner his position was more tenuous than that of his enemies, as he had no lands to base himself on, and relied increasingly on the favour of noblemen such as the Earl of Chester and Peter des Roches, Bishop of Winchester, who supported him due to their disenchantment with the rule of Hubert de Burgh. In 1222 he cooperated with de Burgh to suppress a revolt by the citizens of London, capturing three of the ringleaders and executing them without trial.

A new civil war was averted by the intervention of Simon Langton, Archbishop of York, but after a parley in London on 4 December failed tensions rose again. Threatened with excommunication the "schismatics" returned to the king's court, agreeing on 30 December to give their castles and shrievalties to the king. De Bréauté immediately lost Hertford Castle and the shrievalties of Oxfordshire and Northamptonshire, and lost the rest of his shrievalties by 18 January 1224. The failure of de Bréauté and his allies gave the advantage to de Burgh, who in February 1224 ordered de Bréauté to give up Plympton and Bedford castles, rejecting his claim that Plympton Castle was part of his wife's inheritance. De Bréauté refused to give
