It served in the 1679 Covenanter rising of 1679, as well as Argyll's Rising in June 1685, after which it was expanded to two battalions. When the Nine Years War began in 1689, the first battalion was sent to Flanders; the second served in Ireland, and fought at the 1690 Battle of the Boyne, before joining the First in 1691. The combined unit fought at Steenkerque and Landen, as well as the 1695 Namur. After the Treaty of Ryswick in 1697, the regiment returned to Scotland.
