The Battle of the Somme (1 July to 18 November 1916) was one of the largest and bloodiest battles of the First World War. 

The campaign was a joint operation between British and French forces intended to achieve a decisive victory over the Germans on the Western Front.

In December 1915, Allied commanders had met to discuss strategies for the upcoming year and agreed to launch a joint French and British attack in the region of the River Somme in the summer of 1916. Intense German pressure on the French at Verdun throughout 1916 made action on the Somme increasingly urgent and meant the British would take on the main role in the offensive. 

British troops were faced with German defences that had been carefully laid out over many months. Despite a seven-day bombardment, prior to the attack on 1 July, the British did not achieve the quick breakthrough their military leadership had planned for and the Somme became a deadlocked battle of attrition. 

For many in Britain, the resulting battle remains the most painful and infamous episode of the First World War.

The Battle of the Somme by numbers

The Battle of the Somme resulted in over a million casualties on both sides and by the end of the campaign the British had only advanced seven miles. Find out key facts about the battle including the number of British and German casualties on the first day of the battle. 

Over the next 141 days, the British advanced a maximum of seven miles. More than one million men from all sides were killed, wounded or captured.

British casualties on the first day – numbering over 57,000, of which 19,240 were killed – make it the bloodiest day in British military history.

The Somme, like the Battle of Verdun for the French, has a prominent place in British history and popular memory and has come to represent the loss and apparent futility of the war. 

But the Allied offensive on the Somme was a strategic necessity fought to meet the needs of an international alliance. British commanders learned difficult but important lessons on the Somme that would contribute to eventual Allied victory in 1918.
