The 1916Battle of the Somme was one of the largest battles of the First World War, with more than one million casualties, and also one of the bloodiest battles in human history. The Allied forces attempted to break through the German lines along a 25-mile (40 km) front north and south of the River Somme in northern France. One purpose of the battle was to draw German forces away from the Battle of Verdun; however, by its end the losses on the Somme had exceeded those at Verdun.
While Verdun would bite deep in the national consciousness of France for generations, the Somme would have the same effect on generations of Britons. The battle is best remembered for its first day, 1 July 1916, on which the British suffered 57,470 casualties, including 19,240 dead — the bloodiest day in the history of the British Army to this day. As terrible as the battle was for the British Empire troops who suffered there, it naturally affected the other nationalities as well. One German officer famously described it as "the muddy grave of the German field army." By the end of the battle, the British had learnt many lessons in modern warfare while the Germans had suffered irreplaceable losses. British official historian Sir James Edmonds stated, "It is not too much to claim that the foundations of the final victory on the Western Front were laid by the Somme offensive of 1916."
For the first time the home front in Britain was exposed to the horrors of modern war with the release of the propaganda film The Battle of the Somme, which used actual footage from the first days of the battle.
It resulted in more than a quarter of a million deaths and about half a million wounded. It was the longest battle and one of the bloodiest in World War I. In both France and Germany it has come to represent the horrors of war, similar to the Somme in Britain.
