The 6th Infantry Division was the last division planned as part of the BEF of 1914. It took part in the fighting on the Aisne and the Battle of Armentières in 1914; and then served in the Ypres salient for 18 months (including its recapture of Hooge in August 1915), before its translation to the Somme in 1916 to take part in the Battles of Flers-Courcelette, Morval and the Transloy Ridges. In 1917 it was involved in heavy fighting at Loos as a result of the Battle of Arras, and again in the Battle of Cambrai in November 1917. In 1918 it would bear the brunt of the German offensive as part of Third Army on 21 March, and would finish its war with Fourth Army in the Hundred Days campaign from the Hindenburg Line onwards. A brief operational history was published in 1920. This new history covers the operations in detail, but devotes two chapters to study of the division’s commanders from its four major-generals to its battalion COs; a chapter to the divisional and brigade staff; a chapter to training and another on the development of divisional firepower; and reviews medical services, engineering and logistics. The book seeks to place the division within the context of the tactical and operational development of the British Army in the First World War.
