In 1751, the regiment became the 20th Regiment of Foot, often written in Roman numerals 'XX Foot', (hence the nickname "The Two Tens"). During the Seven Years' War the regiment earned honour at the Battle of Minden on 1 August 1759, when, as an infantry formation, they stood fast and broke a French cavalry charge. During the American Revolutionary War, the regiment was sent to Quebec in April 1776 and assisted in the relief of Quebec in May 1776. Serving under General John Burgoyne for the remainder of the Canadian campaign, they later surrendered along with General Burgoyne at Saratoga.
