Walter de Luci (or de Lucy) was a Benedictine monk at Lonlay-l'Abbaye in Normandy, before being elected Abbot of Battle Abbey in Sussex, England.

[3] Hilary obtained from both Pope Eugene III and Pope Hadrian IV orders to obey the bishop, but in 1157, Walter brought the case before King Henry II of England at a council held at Colchester.

Both documents freed the abbey from ecclesiastical oversight, and Henry II had at his coronation confirmed all his grandfather's charters.

Henry was not impressed by this argument, for it impinged on his royal rights.

[2] Thomas Becket, then Henry's chancellor, was one of the main opponents of Hilary at this council.
