Field Marshal Sir Douglas Haig: The Somme, the BEF & the Hundred Days
Field Marshal Sir Douglas Haig commanded the British Expeditionary Force on the Western Front from December 1915 until the end of the First World War. His name remains inseparable from the Somme and Passchendaele, the enormous casualties of industrial warfare and the later Allied victories of 1918. A useful biography has to hold those parts of his record together rather than choosing either caricature.
Before command of the BEF
Haig entered the British Army in 1884 and served in Sudan and the South African War. He developed a strong reputation for staff work and cavalry expertise and held senior commands before the First World War.
In December 1915 he replaced Sir John French as Commander-in-Chief of the British Expeditionary Force. He inherited an army expanding at extraordinary speed from the small professional force of 1914 into a mass citizen army fighting a continental war.
The Somme, 1916
The Somme offensive was shaped by coalition strategy and by the need to relieve pressure on the French at Verdun. Haig wanted the operation to inflict major damage on the German Army and, if possible, create conditions for deeper exploitation.
On 1 July British forces suffered 57,470 casualties, including 19,240 killed. The battle continued until November and cost all sides enormously.
Haig’s responsibility as commander-in-chief cannot be separated from those losses. At the same time, the Somme was not a single unchanged plan repeated for five months. British artillery methods, infantry tactics, communications and the use of new weapons evolved during the campaign, often through costly experience.
Passchendaele and the controversy over attrition
In 1917 Haig again backed a major offensive in Flanders. The Third Battle of Ypres became associated with mud, shattered ground and heavy casualties. Critics have used the Somme and Passchendaele as evidence that Haig pursued attrition without sufficient regard for cost.
Defenders argue that he faced a strategic problem with few easy alternatives: Germany had to be defeated on land, coalition commitments mattered, and the British Army was still developing the means to break a modern defensive system.
The disagreement is not likely to disappear. The useful historical question is not whether Haig was either a butcher or a genius. It is how his command adapted, where it failed, and what changed between 1916 and 1918.
1918 and the Hundred Days
The German spring offensives of 1918 placed the BEF under severe pressure. After the crisis, Allied command became more closely coordinated under Ferdinand Foch.
From August, British, Dominion, French and American forces launched a succession of offensives that drove the German armies back. The BEF Haig commanded in late 1918 was tactically and technically far more capable than the force that had attacked on 1 July 1916.
That development involved artillery science, tanks, aircraft, platoon firepower, counter-battery methods, logistics, engineering and better staff systems. It was institutional learning across a huge army, not the invention of one commander.
Why Haig matters
Haig matters because the argument around him is really an argument about command in industrial war. Senior commanders made decisions at a scale where success and failure were measured in armies, months and national endurance, while the human cost was paid by individuals and units at the front.
A serious assessment should neither remove Haig’s responsibility from costly decisions nor pretend that another commander possessed an obvious low-cost route to defeating the German Army.
After the war
Haig became closely involved in veterans’ welfare and was a leading figure in the creation of the Royal British Legion. He died in 1928.
