During the Great War of 1914–18 another two home-based battalions were recruited, which were used to supply manpower to the 1st Battalion in France, who served with distinction with the Highland Light Infantry under the 2nd Division at the battles of Festubert and Loos. In May 1916 the battalion was transferred to the 33rd Division and fought at the Somme (at High Wood), Arras and the Third Battle of Ypres. After the end of the war, the Glasgow Highlanders were disbanded along with the rest of the Territorial Force. The story of the battalion in the Great War would later be dramatised in the 1995 Bill Bryden play, "The Big Picnic", starring Jimmy Logan.
