Battle of Delville Wood begins as an action within the Battle of the Somme, lasting until 3 September 1916.

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, with dense hazel thickets, intersected by grassy rides, to the east of Longueval. As part of a general offensive starting on 14 July, which became known as the Battle of Bazentin Ridge (14–17 July), General Douglas Haig, Commander of the British Expeditionary Force, intended to capture the German second position between Delville Wood and Bazentin le Petit.

The Battle of the Somme, also known as the Somme offensive, was a battle of the First World War fought by the armies of the British Empire and the French Republic against the German Empire. It took place between 1 July and 18 November 1916 on both sides of the upper reaches of the river Somme in France. The battle was intended to hasten a victory for the Allies. More than three million men fought in the battle, of whom more than one million were either wounded or killed, making it one of the deadliest battles in human history.
