Nonant was elected bishop in 1185, probably in January, and consecrated on 31 January 1188. The long delay between his election and his consecration was due to Nonant's continued diplomatic efforts on behalf of Henry II. In 1186, he was sent to Rome to secure papal permission for the crowning of Prince John as King of Ireland. The bishop-elect was briefly in England from December 1186 until February 1187, but then went with King Henry to the continent and did not return to England until January 1188. However, when Henry returned to France in July 1188, Hugh accompanied the king and did not return until shortly before the coronation of King Richard I of England. Nonant also purchased the offices of
Sheriff of Warwickshire,
Leicestershire, and
Staffordshire. Holding these offices was against
canon law, and the bishop's tenure in these offices may have been the cause of his quarrel with
Baldwin of Forde. Nonant was very shrewd and eloquent, but he was also violent in his attempts to reform or expel his monastic clergy from Coventry. In October 1189 he attempted to persuade his fellow bishops who had monastic cathedral chapters to expel the monks and replace them with secular clergy. He also attempted to get all the bishops to prosecute a joint case at Rome to expel the monastic cathedral chapters, but gave up that idea after the Archbishop of Canterbury, Baldwin of Exeter declined to go along. Nonant did, however, receive papal sanction for the replacement of monks at Coventry. By 1197, however, Pope
Celestine III issued instructions to
Hubert Walter, the new Archbishop of Canterbury,
Hugh of Lincoln, the
Bishop of Lincoln and
Samson of Tottington, the
Abbot of Bury St Edmunds, to restore the monks to the cathedral. After King Richard went to the Holy Land on the
Third Crusade, Nonant supported the efforts of Prince
John, King Richard's brother, to seize power in England. Nonant joined with John in trying to wrest control of the castles of Tickhill and Nottingham from
William Longchamp, the
Bishop of Ely, who had been named
justiciar and
chancellor during Richard's absence. It was probably Nonant who was responsible for the meeting at Loddon Bridge on 5 October 1191 that ended in the deposition of Longchamp from office. The bishop lost his three sheriffdoms, and retired to Normandy. ==Death and legacy==
