Battle of the Somme

The situation

After failing in 1914-15 to break the muddy stalemate of trench warfare, the Allies developed a new plan. A ‘Big Push’ on the Western Front would coincide with attacks by Russia and Italy elsewhere.

The British wanted to attack in Belgium. But the French demanded an operation at the point in the Allied line where the two armies met. This was along a 25-mile (40km) front on the River Somme in northern France.

On 21 February 1916, aiming to wear down the French in a battle of attrition, the Germans attacked at Verdun. In order to assist their ally, the British launched their attack on the Somme earlier than planned.

Battle plans

Haig’s plan was for the British Fourth Army to break through in the centre, while the Third Army in the north and the French Sixth Army to the south made diversionary attacks. If successful, the Reserve Army, including cavalry, would then exploit this gap and roll up the German line.

The Germans were stationed behind a formidable set of defences, the strength of which had been underestimated by Allied intelligence.

Prelude

On 24 June 1916, the British began a seven-day preliminary bombardment. Haig’s artillery was expected to destroy German defences and guns, and cut the barbed wire in front of the enemy lines. When the attack began, it would provide a creeping barrage behind which the infantry could advance.

The British believed that the Germans would be so shattered by this bombardment that the infantry would rush over and occupy their trenches. But they overestimated their firepower. The guns were too thinly spread for the task in hand.

The British fired 1.5 million shells. Many were shrapnel, which threw out steel balls when they exploded. These were devastating against troops in the open, but largely ineffective against concrete dugouts. A lot of shells were also defective. The German defences were not destroyed and in many places the wire remained uncut.

The Allies also used mines to destroy the German lines before the battle. One was detonated at Hawthorne Ridge 10 minutes before Zero-Hour, unwittingly signalling to the Germans that an attack was coming. 

The first day

At 7.30am on 1 July 1916, 14 British divisions attacked. In most cases they were unable to keep up with the barrage that was supposed to take them through to the German trenches.

This gave the Germans time to scramble out of their dugouts, man their trenches and open fire. Haig’s infantry were met by a storm of machine-gun, rifle and artillery fire. They suffered over 57,000 casualties during the day.

Although the French made good progress in the south and there were some local successes, in most places the attack was a bloody failure. But with the French still under pressure at Verdun, there was no question of calling off the offensive.

From July to November

More attacks between 3 and 13 July resulted in a further 25,000 casualties. But, gradually, the British tactics improved.

On 14 July, four British divisions made a dawn attack on Longueval Ridge. Supported by an intense artillery bombardment, they caught the Germans by surprise and by mid-morning they had captured the ridge.

Attacks continued through the summer, mostly on a series of individual objectives, with the Germans frequently mounting counter-attacks of their own. The Some offensive ultimately included 12 separate battles, many of which became slogging matches that lasted for weeks.

On 18 November 1916, with the weather deteriorating, Haig shut down the offensive. The Allies had only advanced seven miles (12 km) and there was still no breakthrough in sight.

The British Empire had suffered 420,000 casualties and the French 200,000 in the process. German losses were at least 450,000 killed and wounded.

Success or failure? 

For many, the battle exemplified the ‘futile’ slaughter and military incompetence of the First World War. Yet Haig had no option but to fight on the Somme. And despite his controversial tactics, the battle provided a tough lesson in how to fight a large-scale war.

A more professional and effective army emerged from the battle. And the tactics developed there, including the use of tanks and creeping barrages, laid some of the foundations of the Allies’ successes in 1918.

The Somme also succeeded in relieving the pressure on the French at Verdun. Abandoning them would have greatly tested the unity of the Entente.

One German officer described the Battle of the Somme as ‘the muddy grave of the German Field Army’. That army never fully recovered from the loss of so many experienced junior and non-commissioned officers.

In the spring of 1917, the Germans retreated to the ‘Hindenburg Line’, a shortened defensive position. This move was a direct consequence of troop shortages resulting from the Somme fighting.

On a battlefield far, far away...

For many at home, their first glimpse of trench warfare came from Geoffrey Malins's film 'The Battle of the Somme' (1916). 

Filmed at the start of the battle, it mainly shows real events, although some scenes were staged for the camera. The film defined the popular image of the war, and indeed created the genre of war cinema. 

It was also hugely popular with audiences, who hoped to glimpse their loved ones and were shocked to view its graphic depictions of war. During its first six weeks, the film was seen by nearly 20 million people in the UK, almost half the population. This record was only surpassed in 1977 by 'Star Wars'.

Commemorations

Over 150,000 British soldiers are buried on the Somme. The cemeteries there were created by the Commonwealth War Graves Commission (CWGC) and have become sites of pilgrimage and tourism.

The Royal British Legion and the CWGC remember the battle on 1 July each year at Thiepval Memorial. This commemorates 72,000 officers and men who have no known grave.
