the battalion fought in three engagements of the Battle of the Lys: the Battles of Messines, Bailleul and First Kemmel. The following month, the 19th Division's parent unit, IX Corps, was transferred to the French Sixth Army. The division was supposed to rest and re-organise in a quiet sector, but on 27 May the Germans launched a major attack, ensnaring the 8th Battalion in the Third Battle of the Aisne. The battalion saw its last action in October, during the Battle of the Selle, and was disbanded in May 1919. 9th Battalion The 9th Battalion was formed in Bristol in September 1914 and reached France in September 1915 as part of the 78th Brigade in the 26th Division. The division was transferred to XII Corps of the British Salonika Army in November 1915, and the battalion held the line around Tumba, north of Salonika, until July 1916, when the division relieved the French south of Lake Dojran.
