V Corps Cavalry Regiment was assembled in France in May 1916 with the RHQ, A and B Squadrons along with B Squadron, Lothians and Border Horse. In July 1917 the regiment was dismounted and the squadrons were sent to No. 21 Infantry Base Depot at Étaples for infantry training on 23 August. On 29 September, 4 officers and 146 other ranks joined 18th Battalion, Highland Light Infantry in 106th Brigade, 35th Division at Aizecourt-le-Bas which was redesignated as 18th (Royal Glasgow Yeomanry) Battalion, Highland Light Infantry. The battalion was still in 106th Brigade, 35th Division at the end of the war, west of Grammont, Belgium. 2/1st Queen's Own Royal Glasgow Yeomanry The 2nd Line regiment was formed in Glasgow in 1914. It remained there until May 1915 when it moved to Hawick. In March 1916, the regimental HQ, A and B Squadrons joined the 65th (2nd Lowland) Division in Essex. They were later reduced to a single squadron. In January 1917, they moved to Ireland with 65th Division and in February 1918 were absorbed into the 1st Reserve Cavalry Regiment at The Curragh.

As the 1st Line had been converted to infantry, it is probable that some of the men joined the 5th (Reserve) Battalion of the Highland Light Infantry at Catterick.
