Mory village was occupied by Commonwealth troops in the middle of March 1917. It was lost after obstinate defence by the 40th and 34th Division a year later and recaptured towards the end of the following August, after severe fighting, by the 62nd (West Riding) and Guard Divisions. The German burials in a plot on the west side of the cemetery were made by German troops in March-August 1918, or by Commonwealth troops in September 1918. The Commonwealth plots were begun at the end of March 1917 and carried on by fighting units until March 1918, and again in August and September 1918. The graves in Plots IV and V - including many of the Guards Division, and chiefly of 1918 - were added after the Armistice from the battlefields between St. Leger and Bapaume.
