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 and was the largest battle of the First World War on the Western Front . More than three million men fought in the battle and one million men were wounded or killed, making it one of the bloodiest battles in human history . </P> <P> The French and British had committed themselves to an offensive on the Somme during Allied discussions at Chantilly, Oise, in December 1915 . The Allied Powers agreed upon a strategy of combined offensives against the Central Powers in 1916, by the French, Russian, British and Italian armies, with the Somme offensive as the Franco - British contribution . Initial plans called for the French army to undertake the main part of the Somme offensive, supported on the northern flank by the Fourth Army of the British Expeditionary Force (BEF). When the Imperial German Army began the Battle of Verdun on the Meuse on 21 February 1916, French commanders diverted many of the divisions intended for the Somme and the "supporting" attack by the British became the principal effort . </P>
