マルプラケの戦い
At the Battle of Malplaquet in 1709, the regiment's colonel, Cranston, was wounded; Blackadder was promoted lieutenant-colonel and took over command. He led the regiment for two years, through the sieges of Douai and Bouchain, before selling the colonelcy to George Forrester, 5th Lord Forrester in 1711. He left the Army on 12 October.
