The two Territorial Army units, the 7th/9th, which was the 7th and 9th battalions merged, and 8th Battalions, mobilised in Scotland in September; the 7th/9th was briefly deployed to France with the 155th Infantry Brigade, alongside the 4th and 5th King's Own Scottish Borderers, of the 52nd (Lowland) Infantry Division before the collapse of the French government, but was quickly withdrawn. The regiment raised a fifth battalion in June 1940; it was created as the 50th (Holding) Battalion in June 1940 where it would 'hold' men who were medically unfit, temporarily homeless or on a course etc. but redesignated the 12th Battalion in October 1940. Also raised were the 10th and 11th (Home Defence) battalions, raised in late 1939 specifically for defensive duties in the United Kingdom. Both battalions, like most others of the same type, would have consisted mainly of older and less fit men, with previous military experience, together with younger soldiers. The 11th, however, was disbanded in 1940 and, in 1941, the 10th dropped the 'Home Defence' subtitle and was redesignated as the 30th Battalion but was disbanded in 1943.
