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 French Empire 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 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. The Battle of the Somme was fought in the traditional style of World War I battles: trench warfare. The trench warfare gave the Germans an advantage because they dug their trenches deeper than the allied forces which gave them a better line of sight for warfare. The Battle of the Somme also has the distinction of being the first battle fought with tanks. However, the tanks were still in the early stages of development, and as a result, many broke down after maxing out at their top speed of 4 miles per hour.
