The 2nd battalion, along with the 2nd battalion of the 47th Regiment of Foot and the 2nd battalion of the 84th Regiment of Foot, was attached to Major-General Lord Aylmer's independent brigade during Wellington's offensive across the Pyrenees beginning in 1813. The 2nd battalion then moved on in preparation for the Battle of Bayonne when the war ended. The 2nd battalion was then sent to Ireland after a brief period of occupation duties in France.
