The Second Battle of the Somme of 1918 was fought during the First World War on the Western Front from late August to early September, in the basin of the River Somme. It was part of a series of successful counter-offensives in response to the German Spring Offensive, after a pause for redeployment and supply. The most significant feature of the 1918 Somme battles was that with the first Battle of the Somme of 1918 having halted what had begun as an overwhelming German offensive, the second formed the central part of the Allies' advance to the Armistice of 11 November.
