13th (Service) Battalion (Wandsworth), East Surrey Regiment

Formation
The Battalion was formed in Wandsworth by the Mayor on 16 June 1915, and the War Office recognised the battalion on 28 August 1915. There also was the 14th (Service) Battalion (Wandsworth), East Surrey Regiment but that battalion was absorbed to make the full strength of this battalion.

1916
The Battalion Landed at Le Harve on the 4th June 1916, they were then moved to Lens and from there with the 40th Division moved to the Hohenzollern Redoubt. Where they relieved the 12th Battalion, Suffolk Regiment, the battalion hadn't been involved in major actions at the Hohenzollern Redoubt but artillery bombardment was starting to take a toll on the battalion with casualties being 16% of the battalion. The battalion was then put into reserve for the next months while the 40th Division was being relived. The battalion was then temporarily attached to the 49th Division to help relive the 4th Battalion, King's Own Yorkshire Light Infantry at Hébuterne near the town of Albert. They soon rejoined the 40th Division and marched to Bouchavesnes Area near the Somme Valley where they spent their Christmas.
