He received lands in Herefordshire and Shropshire, and served King William I of England by leading military forces during 1075.
These two groupings of lands allowed Walter to help defend the border of England against Welsh raids.
Walter kept a large number of his manors in demesne, managing them directly rather than giving them as fiefs to his knightly followers.
[7] In total, Domesday Book records Walter's lands as being worth £423 in income per year and as comprising 163 manors in 7 different counties.
[9] In 1075, Walter was one of the leaders of the force that prevented Roger de Breteuil from joining up with the other rebels during the Revolt of the Earls.
[13] The elder Walter died on 27 March 1085,[2] falling off some scaffolding at Saint Guthlac's Priory when he was inspecting the progress of the building at that monastery.
