Lord Grey continued in office until 1540, and although, from the English point of view, he ruled well and successfully, on his return to England he was imprisoned and subsequently executed, the ostensible reason being his partiality for the Kildares.
Grey was replaced by a remarkable man, Sir Anthony St. Leger, whose three terms of office covered thirteen years. Sir William Brereton, a foolish person, was the deputy until St. Leger arrived, and distinguished himself by leading a vast army in search of a phantom enemy. St. Leger, from the moment he arrived in Ireland, set about restoring some order in the country, and he succeeded so well that the historians of the period call attention to the amazing fact that the sight was actually seen of English lords and Irish chiefs meeting in the same chamber and proclaiming Henry VIII. King of Ireland. St. Leger went further than this, and actually paid the debts incurred during his viceroyalty.
Religious persecution
In 1548 he was recalled, and Sir Edward Bellingham ordered to act as deputy and to punish those Irish who had not become Protestants by Act of Parliament. This was a new feature in Irish politics, but Bellingham found diplomacy, force, and threats, and persecution equally ineffective, and he retired in disgust. Sir Francis Bryan followed as deputy in 1550, but he died the same year, and Brabazon, hastily elected in his stead, retired when Sir Anthony St. Leger returned, to be welcomed by all classes. He held office until 1556, save for a period between 1551-52, when Sir James Croft represented him, and when he retired he had the satisfaction of knowing that he left Ireland better off than when he found it.
The appointment of the Earl of Sussex, however, undid all St. Leger's good work, and the new deputy had immediately to take the field. He was lucky, however, to find the Irish chiefs quarrelling amongst themselves, and in the circumstances victory was achieved easily. The O'Neills, headed by the famous Shane, advanced against him, but Sussex defeated them with great slaughter, and the chieftain escaped the battlefield to die a dishonourable death in a drunken brawl.
England had greater attractions for the earl than Ireland could offer, and he returned there in 1557, nominating Sir Henry Sidney and the Lord Chancellor as vice-deputies. Elizabeth, immediately after her accession, sent the viceroy back, but he returned again to London. Hugh Curwen, Archbishop of Dublin, anxious to retain his office as well as that of joint representative with Sir Henry Sidney of the absent viceroy, conveniently changed his religion now that a Protestant was on the throne, and to show the genuineness of his conversion he had the pictures that adorned the walls of Christ's Church and St. Patrick's whitewashed.
Earl of Essex
When the Earl of Sussex was recalled in 1564, Sir Henry Sidney was appointed deputy or viceroy, and he acted for fourteen years. What he thought of the appointment may be inferred from a letter he wrote on his return after a brief absence in 1575. Sir William Fitz-William had acted as his deputy, and no doubt Sidney hoped that Elizabeth might give him a more congenial task. He declares that he 'took on for the third time that thankless charge, and so, taking leave of Her Majesty, kissed her sacred hands, with most gracious and comfortable words, departed from her at Dudley Castle, passed the seas, and arrived September 13, 1575, as near the city of Dublin as I could safely, for at that time the city was grievously infected with the contagion of the pestilence.' In the depth of winter he went to Cork, and passed Christmas there. The following February he visited Thomond, Earl of Clanricarde, and caused two of his sons to make public confession of their rebellion and sue for his pardon. Sidney, in recounting this, adds fervently, 'whom would to God I had hanged!'
