Fitzwalter effected Queen Mary's policy for Ireland: the reversal of the partial attempts that had been made during the short reign of Edward VI to promote Protestantism there, the plantation by English settlers in the midlands and the shiring of King's County and Queen's County in 1556, named after Mary and her husband Philip. But before Fitzwalter could attend to such matters he had to make an expedition into Ulster, which was being kept in a constant state of disturbance by the Highland Scots from Kintyre and the Islands who were making settlements along the Antrim coast in the district of the Glynnes (now known as the Glens of Antrim), and by the efforts of Shane O'Neill to dominate more territory in Ulster. Brutal methods were deployed, as Sussex sent the earl of Ormond, Sir Nicholas Bagenal and other captains to Rathlin Island on 3 September 1557. They stayed for three days and hunted down the occupants of the island, and it was noted that the killed 'as many as they might come by or get out of caves, both man, woman, child and beasts'.
