St-Calais managed the king's case against Anselm at Rockingham in 1095, when Anselm wished to go to receive his pallium from Pope Urban II. At that time St-Calais opposed Anselm's attempt to appeal to Rome over the issue, and steadfastly maintained the king's position against Anselm, even advocating that the archbishop be deprived of his lands and sent into exile. Later, when the king was negotiating with Walter of Albano, the papal legate sent by Urban to convey the pallium to Anselm and to secure the king's recognition of Urban as pope, St-Calais was the king's chief negotiator. The clerical reformers, Eadmer among them, who supported Anselm in these quarrels, later tried to claim that St-Calais had supported the king out of a desire to succeed Anselm as archbishop if Anselm was deposed, but it is unlikely that St-Calais seriously believed that Anselm would be deposed. St-Calais secured grants from the king in return for his services. His efforts on behalf of the king earned him hostile accounts in Eadmer's later writings.
