Edward IV relied on him for both land and naval warfare. Following the victory at Towton, he took part in the gradual establishment of royal control in Northumberland, heading a garrison of 120 men at Newcastle in the summer of 1461, and taking part in the siege of Alnwick in November 1462. Between these dates, he was back in Calais, raiding the Breton coast in August 1462, then burning Le Conquet near Brest, and raiding the Ile de Re.
