The Battle of Delville Wood (15 July – 3 September 1916) was a series of engagements in the 1916 Battle of the Somme in the First World War, between the armies of the German Empire and the British Empire. Delville Wood (Bois d'Elville), was a thick tangle of trees, chiefly beech and hornbeam (the wood has been replanted with oak and birch by the South African government), with dense hazel thickets, intersected by grassy rides, to the east of Longueval.
