Returning to England from a mission to
Charles V, Holy Roman Emperor, in April 1556, Fitzwalter was appointed
Lord Deputy of Ireland. According to the
Encyclopædia Britannica Eleventh Edition, the "prevailing anarchy in Ireland, a country which, nominally subject to the English Crown, was torn by feuds among its practically independent native chieftains, rendered the task of the lord deputy one of no ordinary difficulty; a difficulty that was increased by the ignorance of English statesmen concerning Ireland and Irish conditions, and by their incapacity to devise or to carry into execution any consistent and thorough-going policy for bringing the half-conquered island under an orderly system of administration." 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 they killed 'as many as they might come by or get out of caves, both man, woman, child and beasts'. Having defeated O'Neill and his allies, the MacDonnells, the lord deputy, who by the death of his father in February 1557 became Earl of Sussex, returned to Dublin, where he summoned a parliament in June of that year. Statutes were passed declaring the legitimacy of
Mary I of England as Queen of the
Kingdom of Ireland, reviving the laws for the suppression of heresy and forbidding the immigration of Scots. Having carried this legislation, Sussex endeavoured to give forcible effect to it, first by taking the field against
Donough O'Conor, whom he failed to capture, and afterwards against Shane O'Neill, whose lands in
Tyrone he ravaged (causing artificial famine by the burning of crops and killing of livestock), restoring to their nominal rights the
Earl of Tyrone and his reputed son
Matthew O'Neill, Baron of Dungannon. In June of the following year Sussex turned his attention to the west, where the head of the O'Brien clan had ousted his nephew
Conor O'Brien, Earl of Thomond, from his possessions, and refused to pay allegiance to the Crown; he forced
Limerick to open its gates to him, restored Thomond, and proclaimed The O'Brien a traitor. , In the autumn of 1558 the continued inroads of the Scottish islanders in the
Antrim glens called for drastic treatment by the lord deputy. Sussex sailed from Dublin in the
Mary Willoughby to
Campbeltown Loch on the
Kintyre peninsula. He burnt farms and houses including
Saddell, a castle of
James MacDonnell or MacDonald of
Dunyvaig and Glynnes (died 1565), and then marched south to burn
Dunaverty and Machrimore. He then burnt farms on the islands
Arran,
Bute, and
Cumbrae. Landing at
Carrickfergus, he fired and plundered the settlements of the Scots on the Antrim coast before returning to Dublin for Christmas. In the metropolis, the news reached him of the queen's death. Crossing to England, he took part in the ceremonial of
Queen Elizabeth's coronation in January 1559; and in the following July, he returned to Ireland with a fresh commission, now as lord lieutenant, from the new queen, whose policy required him to come to terms if possible with the troublesome leaders of the O'Neills and the MacDonnells. Shane O'Neill refused to meet Sussex without security for his safety, and having established his power in Ulster he demanded terms of peace which Elizabeth was unwilling to grant. Sussex failed in his efforts to bring Shane to submission, either by open warfare or by subterfuge. He was preparing for a fresh attempt when he was superseded by
Gerald FitzGerald, 11th Earl of Kildare, who was commissioned by Elizabeth to open negotiations with O'Neill, the result of which was that the latter repaired to London and made a formal submission to the queen. Shane's conduct on his return to Ireland was no less rebellious than before, and energetic measures against him became more imperative than ever. Having obtained Elizabeth's sanction, Sussex conducted a campaign in the summer of 1563 with
Armagh as his temporary headquarters; but except for some indecisive skirmishing and the seizure of many of O'Neill's cattle, the operations led to no result and left O'Neill with his power little diminished. His continued failure to effect a purpose for the accomplishment of which he possessed inadequate resources led Sussex to pray for his recall from Ireland, and his wish was granted in May 1564. His government of Ireland had not, however, been wholly without fruit. == Sussex the politician ==
