In 1914 Haig obtained the rank of Lieutenant General and was given command over the 1st Army Corps of the British Expeditionary Force (BEF) in France and Belgium. Haig commanded his forces at Mons and was praised for his Ypres campaign in 1914. Later in the same year, Haig was promoted to full general and was given command of the recently enlarged BEF. In December 1915, Haig was appointed commander in chief of the BEF. Haig now become under extreme pressure from the French to produce a diversion from Verdun. The first Battle of the Somme was fought from July to November 1916. In that time Allied forces advanced 12km and suffered 420,000 British and 200,000 French casualties.
After the war Haig was posted as commander in chief of home forces until his retirement in 1921. Haig, who was granted £100,000 by the British government, devoted the rest of his life to the welfare of ex-servicemen via the Royal British Legion. Douglas Haig died in 1928.
The Battle of the Somme was planned as a joint French and British operation. The idea originally came from the French Commander-in-Chief, Joseph Joffre and was accepted by General Haig, the British Expeditionary Force (BEF) commander, despite his preference for a large attack in Flanders. Although Joffre was concerned with territorial gain, it was also an attempt to destroy German manpower. General Sir Henry Rawlinson was in charge of the main attack and his Fourth Army was expected to advance towards Bapaume. To the north of Rawlinson, General Edmund Allenby and the British Third Army were ordered to make a breakthrough with cavalry standing by to exploit the gap that was expected to appear in the German front-line.
Haig used 750,000 men (27 divisions) against the German front-line (16 divisions). However, the bombardment failed to destroy either the barbed-wire or the concrete bunkers protecting the German soldiers. This meant that the Germans were able to exploit their good defensive positions on higher ground when the British and French troops attacked at 7.30 on the morning of the 1st July. The BEF suffered 58,000 casualties (a third of them killed), therefore making it the worse day in the history of the British Army. Haig was not disheartened by these heavy losses on the first day and ordered General Henry Rawlinson to continue making attacks on the German front-line. A night attack on 13th July did achieve a temporary breakthrough but German reinforcements arrived in time to close the gap. Haig believed that the Germans were close to the point of exhaustion and continued to order further attacks expected each one to achieve the necessary breakthrough.
I think Douglas Haig was not a Butcher. The Somme was a diversion wanted by the French and Haig did it for them. If the Somme had not been fought then the Germans could have broken through Verdun and taken France. Douglas Haig was not used to modern warfare, no-one was and Haig tried his best in situations that he had never come across before. Another point to consider is that Germany had the most casualties in the battle of the Somme which shows that the tactics used by Haig did work, although they didn't work very effectively.
