# William Stewart, 1st Viscount Mountjoy

William Stewart, 1st Viscount Mountjoy (1653–1692), was an Anglo-Irish soldier.

## Early life

William Stewart was born in 1653, the son of Sir Alexander Stewart, 2nd Baronet, of Ramelton. His family was from Donegal, Ulster Scots, and Protestant.

## Career

He was appointed master-general of the ordnance and colonel of a regiment of foot. In 1682 Charles II created him Viscount Mountjoy and Baron Stewart in the Peerage of Ireland.
In 1686 Mountjoy served the Holy League (1684) in Hungary at the Siege of Buda, where he was twice dangerously wounded.
On his return to Ireland, he was made a brigadier-general. Macaulay styled him "a brave soldier, an accomplished scholar". In Dublin he was the centre of a small circle of learned and ingenious men, who had, under his presidency, formed themselves into a Royal Society.
In 1685 Charles II died and King James II acceded to the throne. James started replacing Protestants in Ireland with Catholics. In 1687 James appointed a new viceroy: Richard Talbot, Earl Tyrconnell.
In 1688 James asked Tyrconnell for good Irish troops to defend England. These troops left in September and October 1688. Tyrconnell felt it necessary to replace these troops and decided to raise four new regiments one for each Irish province. The regiment for Ulster was to be raised by the Earl of Antrim, a Catholic nobleman of Scottish origin. Antrim, already in his seventies, hired 1,200 Scottish mercenaries (i.e. redshanks), making sure they were all Catholics. The unit should have been ready by 20 November, but delays occurred.
In 1688, Mountjoy commanded the regiment stationed in Derry. During the Glorious Revolution he stayed loyal to James while most Protestants declared for the Prince of Orange. Nevertheless, Tyrconnell did not trust Mountjoy and sought to garrison Derry with more reliable troops. On 23 November 1688 Tyrconnell ordered Mountjoy to march to Dublin for embarking to England. He then sent Alexander MacDonnell, Earl of Antrim to occupy Derry with his newly raised regiment, but when Antrim eventually reached the city on 7 December, he found the gates shut against him by the 13 apprentice boys. This was the beginning of the Protestant revolt in Ulster. Tyrconnell then sent Mountjoy back to Derry. Mountjoy succeeded to strike a deal with the town on 21 December, and two of the companies of his regiment, consisting entirely of Protestants, were let into the town. Mountjoy became governor of Derry but soon delegated the office to Robert Lundy.
Despite this success, Tyrconnell decided to get rid of Mountjoy. He asked him to accept a diplomatic mission to France together with Stephen Rice. After some hesitations, Mountjoy agreed and he and Rice left for France on 10 January 1689. However, Rice had secret letters from Tyrconnell for Louis XIV that insinuated that Mountjoy should be arrested. He was accordingly thrown into the Bastille and kept there until 1692. While he was imprisoned, the Parliament of Ireland passed a bill of attainder requiring Stewart and two to three thousand others to report to Dublin for sentencing; Stewart in particular was directed to break out of the Bastille in order to report, under pain of being drawn and quartered."
In April 1692 Mountjoy was exchanged for Richard Hamilton. On his release from the Bastille, he did indeed switch loyalties and joined William's army in Flanders as a General, losing his life at the battle of Steenkerque on 3 August 1692.

## Family
