Sir William Stewart, Viscount Mountjoy
Stewart, Sir William, Viscount Mountjoy, was born in 1653. In 1682 he was raised to the peerage, and appointed Master-General of the Ordnance and colonel of a regiment of foot. In 1686 he served in Hungary at the siege of Breda. On his return to Ireland he was made a brigadier-general. Macaulay styles him "a brave soldier, an accomplished scholar. .. At 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 1688 he commanded a portion of the royal army stationed at Londonderry. But as he was a Protestant, Tirconnell, fearing his influence in favour of William, sent him, at the outbreak of hostilities, on a diplomatic mission to France, secretly intimating that his detention would be desirable. He was accordingly thrown into the Bastile, and kept confined there until 1692. On his release, he joined King William's army in Flanders, and lost his life at the battle of Steenkirk, 24th August 1692, aged about 39.
