In December 1777, John Campbell of Barbreck received letters of service from King George III to raise a regiment of infantry in the county of Argyll for service in the regular army. Campbell had held a commission in the old 78th, or Fraser's Highlanders during the French and Indian War. Most regimental officers were commissioned in 1777, but the first muster of the regiment was not held until April 1778. It was inspected at Glasgow in May 1778 and sailed for Halifax, Nova Scotia, in August 1778. The regiment's flank companies (the grenadier and light infantry companies) joined the main British army in New York in the spring of 1779. The Light Company had also served in Virginia in 1781, ending as part of Lord Cornwallis' army that had surrendered at Yorktown in October 1781 and remaining as prisoners until the end of the war in 1783, when they had returned to New York. The regiment, now complete, returned to Great Britain in 1784, landing at Portsmouth and marching from there to Stirling, where it was disbanded on 24 May 1784.
