July 1, 1916 at Somme

The first day on the Somme, 1 July 1916, was the opening day of the British and French offensive that became the Battle of the Somme. The middle day of the middle year of the First World War, it is remembered as the bloodiest day in the history of the British Army when 57,470 men became casualties of which 19,240 were killed or died of wounds. In terms of British casualties, the first day on the Somme is only surpassed by the Fall of Singapore when over 80,000 Allied soldiers became prisoners of war.

For many people, the first day has come to represent the futility and sacrifice of the war, with lines of infantry being mowed down by German machine guns. While the first day marked the beginning of four and a half months of attrition, it has always overshadowed the days that followed.

1 July marked the start of the first phase of the Battle of the Somme, officially known as the Battle of Albert, which continued until 13 July, the eve of the next major attack, the Battle of Bazentin Ridge.

In 1971 British military historian Martin Middlebrook wrote The First Day on the Somme, a detailed analysis of events leading up to and during the British attack on 1 July. It remains one of the most influential books on British First World War history.

The Somme was to be the first major offensive mounted by the British Expeditionary Force and the first battle to involve substantial numbers of battalions from Lord Kitchener's New Army. Included were many of the famous Pals battalions that had formed in response to Kitchener's call for volunteers in August 1914. Heavy losses amongst these battalions led to a concentration of casualty notices in the communities from which they were formed.

The first day was unusual in that the British Army contingent was almost entirely from Britain and Ireland. Since early 1915 the Canadian divisions had been featuring prominently in British battles and as the struggle on the Somme wore on, the Anzacs and South Africans were called upon but on the first day the only non-British troops attacking on the British sector were small units from Bermuda and Newfoundland. (The South African Infantry Brigade and an Indian cavalry division were in reserve and Canadian artillery were involved in the bombardment.)

For Newfoundland, the first day has special significance. The 1st Battalion of the Newfoundland Regiment, at the time the Dominion's entire military contribution to the war, was virtually wiped out in a mishandled attack near Beaumont Hamel (600 out of 800 killed in 30 minutes). After the war the Newfoundland government bought 40 acres (162,000 mÐ'І) around the site of the battalion's attack and created the Newfoundland Memorial Park to commemorate the dead.

Little emphasis has been placed on the French contribution on the first day on the Somme. This is partly because the French attack, which was largely successful, was overshadowed by the disaster that befell the British divisions. Also the French at the time were still occupied with defending Verdun. Nevertheless the French contribution on the Somme was substantial and it is significant that the only British successes of the first day came on the southern sector neighbouring the French XX Corps.

The British plan for the Somme offensive was to achieve a breakthrough which could be exploited by cavalry. Once the German front was penetrated, a mobile force would sweep north towards Arras, rolling up the German line. However, the British had sufficient experience in trench warfare to be prepared for the battle becoming attritional.

The Allies were confronted by three lines of German defences, the first two being complete while the third was still under construction. The approximate centre line of the battlefield was defined by the Roman road that ran straight from Albert in the west to Bapaume in the east. The Somme river ran east-west some 5 miles south of the road.

The main attack was to be carried out by the Fourth Army under the command of General Sir Henry Rawlinson. A diversionary attack was to be made on the northern flank by two divisions of General Edmund Allenby's Third Army. When the breakthrough was achieved, the exploitation phase would be carried out by the three cavalry divisions of General Sir Hubert Gough's Reserve Army. For all three men, the Somme would be their first battle in command of an army.

The main French effort would be carried out by the French Sixth Army of General Marie Emille Fayole. The southern-most French army on the Somme was the French Tenth Army of General Alfred Micheler which would play a small role in the battle. These two armies were part of the French Northern Army Group, commanded by General Ferdinand Foch from 3 July, 1916.

The natural division between the British and French forces would have been the wide marshland along the Somme River but instead the French commander-in-chief, General Joseph Joffre, placed the French XX Corps north of the Somme alongside the southernmost Fourth Army unit (British XIII Corps) so that the British were unable to act independently.

The British and French on the Somme were confronted by the German Second Army of General Fritz von Below. The Germans became aware of preparations for an Allied offensive in April but were dismissive of the threat posed by the British forces, considering them of "limited combat value".
