 Robert rewarded Ranulf for his advice during the invasion by entrusting him with the administration of the see of Lisieux . After Robert 's defeat by Henry at Tinchebray in 1106 , the bishop was among the first to make his peace with Henry , and returned to Durham . He retired from political life . Henry had already replaced him with Roger of Salisbury an able financier who was infinitely more acceptable to the nation . Although some historians have theorized that Ranulf 's time in Normandy was as an agent of Henry , it appears that Ranulf was mainly looking out for his own interests and those of his family .
