Being made colonel in 1689-90, he distinguished himself by his bravery at the battle of the Boyne; and soon after, at those of Aghrim, Steinkirk, and Landen, and at the sieges of Athlone, Limerick, and Namur. His eminent services in Ireland and Flanders, through the whole course of the war, recommended him so highly to King William III. that, in 1696, he advanced him to the dignity of a peer of Scotland, by the title of earl of Orkney; and his lady, the sister of Edward Viscount Villiers, afterwards earl of Jersey, had a grant made to her, under the great seal of Ireland, of almost all the private estates of the late King James, of very considerable value.

In the beginning of 1710, his lordship, as one of the 16 peers of Scotland, voted for the impeachment of Dr Sacheverel; and the same year was sworn of the privy-council, and made general of the foot in Flanders. In 1712, he was made colonel of the royal regiment of fusileers, and served in Flanders under the duke of Ormond. In 1714, he was appointed gentleman-extraordinary of the bed-chamber to King George I. and afterwards governor of Virginia. At length he was appointed constable, governor, and captain of Edinburgh castle, lord-lieutenant of the county of Clydesdale, and field-marshal. He died at his house in Albemarle-street, in 1737.
