marred by the escape that year of another prisoner under his supervision, for which he was fined 300 marks. Back in favour in 1209, he was sent again on a diplomatic mission to Scotland but does not seem to have gone to Palestine, for in 1210 he was serving with John in Ireland. In 1212, on account of him entering a monastic order, John gave custody of his lands to Sir Philip Oldcoates. But he re-entered secular life the next year, when the King made him sheriff of Cumberland and appointed him to a commission investigating grievances in Lincolnshire and Yorkshire. In the latter county, he worked for a reconciliation between John and William de Forz, heir to the extensive estates there of Hawise, Countess of Aumale. In October 1213 he was one of the witnesses when John surrendered England to the authority of the Pope and he was one of the twelve guarantors appointed to ensure John kept his promises. Throughout the disturbances of 1214 and the first quarter of 1215 he remained loyal to John, being rewarded with royal manors in Cumberland and royal support for the election of his aunt as abbess of Barking Abbey. However he then joined the rebel barons as one of the 25 chosen to enforce observance of the Magna Carta agreement, being appointed by them to control Yorkshire and possibly Northumberland. For this he was excommunicated by the Pope, and John gave his lands to William de Forz. Ordered by John to give up Carlisle Castle, he did so but remained on the rebel side after the death of John in October 1216, supporting Prince Louis even after his elder son was captured by the loyalist side in May 1217. He finally submitted later that year, and regained most of his lands. Intermittent unrest in Yorkshire continued, with fighting in 1220 between his men and those of the sheriff, followed in 1221 with him being summoned to help take and destroy Skipsea Castle during the rebellion of William de Forz. In 1225 he was one of the witnesses to the reissue of Magna Carta and by the end of 1226 had re-entered a monastic order, possibly the Knights Templar. His Helmsley estates, where he had fortified the castle, then went to his elder son, while Wark, also fortified by him, went to the younger. He died that year, or in 1227, and
