Plot I of the extension contains the graves of men who died on the Somme front from September 1915 to June 1916.
The graves in Plot II relate to the Somme offensive of July and August 1916 and those in Plot III to the operations of the autumn of 1916.
In the spring of 1917, the front line moved to the east and it was not until the German advances of April 1918 which came to a halt just east of the cemetery that further burials were made in Plot IV.
The botanist Sir Arthur Hill visited Forceville Communal Cemetery and Extension. Hill was an Assistant Director at the Royal Botanical Gardens, Kew, and was sent by the Commission to visit the cemeteries to make recommendations on planting.
