The Extension was used by fighting units and Field Ambulances from August 1915 to November 1916, and more particularly in and after mid to late 1916, when Field Ambulances were concentrated at Albert due to the Battle of Albert 1916 and the wider Somme Campaign. From November 1916, the 5th Casualty Clearing Station used it for two months. From March 1917 to February 1918, it was not used, until 4 burials in March 1918. Plot II was created in August 1918 by the 18th Division.
