The Battle of Somme was a major World War I battle that took place from July to November 1916 along a 30km front in northern France. Over 1 million British and French soldiers attacked German positions, but suffered over 600,000 casualties, especially on the first day where 58,000 British soldiers were killed. The battle resulted in small territorial gains for the Allies but drained German resources. New technologies like tanks were first used during the Somme but had limited success. By November heavy snow and losses on both sides ended the offensive.
