The Battle of the Somme was a major First World War offensive fought between 1 July and 18 November 1916 on both sides of the Somme River in northern France. It involved British and French forces against the German Army and became one of the deadliest battles in human history, with more than one million casualties and only limited territorial gains.

Background
