In March 1743, the regiment was assembled at Perth in preparation for moving to London, then Flanders to join British forces fighting in the War of the Austrian Succession. Scottish officials, including the Lord President of the Court of Session, Duncan Forbes warned the government this was contrary to a general understanding their service was restricted to Scotland. Assured the move was only because George II wanted to inspect them, they arrived in London in May and were then ordered to Gravesend for shipment to Flanders. Anger at the deception, allied to rumours they were going to the West Indies, a location notorious for high mortality rates, caused a mutiny; they set out for Scotland, led by Corporals Malcolm and Samuel MacPherson and Private Farquhar Shaw. They reached Ladywood on the outskirts of Oundle, Northamptonshire on 22 May before being intercepted. The mutineers surrendered in hope of a free pardon, but were marched back to London and incarcerated in the Tower of London. The three leaders of the mutiny were subsequently court-martialled and executed by firing squad on 18 July 1743, at Tower Green. Two hundred other members of the regiment were distributed variously to garrisons in Jamaica, Gibraltar and Menorca, with the remainder shipped to Flanders.
