A concentration cemetery, first established during the fighting, but greatly increased in size after the armistice, when the surrounding fields and smaller cemeteries scattered throughout them were cleared and brought in. There are now 3,137 casualties of the First World War buried or commemorated here. 1,644 of them are unidentified, and there are special memorials to 83 soldiers known or believed to be buried among them, mostly along the lower wall. Other special memorials record the names of five casualties buried in Ginchy A.D.S. Cemetery, whose graves were destroyed by shell fire, and three officers of the 2nd Bn. Coldstream Guards, killed in action on 26 September 1916 and known to have been buried together beside the road near Lesboeufs, but whose grave could not later be located.
