Following its participation in the Canadian campaign of 1776, the regiment was assigned to serve as part of Major-General John Burgoyne's forces. The regiment served under Burgoyne at the Battle of Saratoga in September 1777. The regiment was brigaded with the 9th, 20th, and 21st regiments under the command of Major-General James Inglis Hamilton. The regiment surrendered along with the rest of the force and most of the regiment remained imprisoned until 1781 when they were repatriated to England. In 1782, now under the command of Lieutenant Colonel Alexander Campbell, the regiment was given, for the first time, the county title "Wiltshire".
