 William remained a crown hostage for many months, and was released following the peace resulting from the terms agreed at Winchester on 6 November 1153, by which the civil war was ended.As a younger son of a minor nobleman, William had no lands or fortune to inherit, and had to make his own way in life.Around the age of twelve, when his father's career was faltering, he was sent to the Château de Tancarville in Normandy to be brought up in the household of William de Tancarville, a great magnate and cousin of young William's mother.
