In 1139 supporters of Roger and his family brawled in public with some men who supported
Alan of Brittany. At a court held at Oxford in June 1139, Stephen required Roger of Salisbury, Alexander of Lincoln, and Nigel to surrender their castles as a consequence of the brawl. When Roger and his family delayed, the king ordered their arrest. The king threatened to hang Roger in front of the castle unless it capitulated, and Nigel, under pressure from Roger's wife, surrendered the castle after the siege had lasted three days. All three bishops then submitted and surrendered their secular offices and castles. They were, however, allowed to retain their dioceses. Stephen promptly gave Newark to Robert, Earl of Leicester, who was in turn excommunicated by Alexander of Lincoln. Stephen's brother, Henry of Blois, who was
Bishop of Winchester and
papal legate in England, In the end, the appeal never reached Rome. Part of the problem confronting the assembled bishops was that Stephen had not expelled Roger's family from their ecclesiastical offices, merely their secular ones. Stephen's representatives argued that the bishops had given up their castles and money voluntarily to avoid secular charges. The defence taken by the king was not novel; it had been used before by WilliamI and WilliamII against
Odo of Bayeux and
William de St-Calais, respectively. Traditionally, the arrest of the bishops has been seen as a turning point in Stephen's reign, and the event that turned the ecclesiastical hierarchy against him. Recent historians have held a lively debate on the issue; a few still hold to the traditional interpretation, but most have decided that reactions in the English church were more ambivalent. One modern historian,
David Crouch, believes that the arrest of the bishops signalled the beginnings of the
Anarchy, not because of any alienation of the church, but through court politics, where Stephen showed himself incapable of manipulating the factions of his court. Even his own cathedral chapter refused to support him, and his revolt collapsed in January. Nigel took refuge at the court of Stephen's rival, the Empress Matilda, It appears likely that Nigel appealed to Pope
Innocent II at this time, for in October 1140 Innocent issued a
papal bull, or papal instruction, ordering the restoration to Nigel of the lands of his bishopric, and it appears that after the capture of Stephen, Matilda managed to restore Nigel to Ely briefly. Ultimately, this agreement came to nothing when Matilda's chief supporter, her half-brother Robert of Gloucester, was captured and later exchanged for Stephen. Stephen's release meant that the king was free to send
Geoffrey de Mandeville against Nigel, and Nigel submitted to the king, probably in 1142. ==Stephen's later reign==
