On 1 July 1916, the first day of the Battle of the Somme, the 8th Division attacked Ovillers and the 34th Division La Boisselle. The villages were not captured, but ground was won between them and to the south of La Boisselle. On 4 July, the 19th (Western) Division cleared La Boisselle and on 7 July the 12th (Eastern) and 25th Divisions gained part of Ovillers, the village being cleared by the 48th (South Midland) Division on 17 July. The two villages were lost during the German advance in March 1918, but they were retaken on the following 24 August by the 38th (Welsh) Division.  Ovillers Military Cemetery was begun before the capture of Ovillers, as a battle cemetery behind a dressing station. It was used until March 1917, by which time it contained 143 graves, about half the present Plot I. The cemetery was increased after the Armistice when Commonwealth and French graves where brought in, mainly from the battlefields of Pozieres, Ovillers, La Boisselle and Contalmaison.  The cemetery was designed by Sir Herbert Baker.
