The British 31st Division was a New Army division formed in April 1915 as part of the K4 Army Group and taken over by the War Office on 10 August 1915. Comprising mainly battalions from Yorkshire and Lancashire, the division was sent to Egypt in December 1915 before moving to France in March 1916 and spent the remainder of the First World War in action on the Western Front. The 31st Division was the quintessential New Army division, being made up entirely of Pals battalions.
