The regiment embarked for Flanders in June 1744 and saw action at the Battle of Fontenoy in May 1745 during the War of the Austrian Succession. It was ordered home in September 1745 as part of the government response to the Jacobite rebellion and were in the right wing of the front line at the Battle of Culloden in April 1746. In 1751 a royal warrant declared that regiments should no longer be known by the name of their colonel, but their number in the order of precedence, and Conway's duly became the 34th Regiment of Foot.
