Field Marshal Douglas Haig, 1st Earl Haig, KT, GCB, OM, GCVO, KCIE was a senior officer of the British Army. During the First World War, he commanded the British Expeditionary Force on the Western Front from late 1915 until the end of the war. He was commander during the Battle of the Somme, the Battle of Arras, the Third Battle of Ypres, the German Spring Offensive, and the final Hundred Days Offensive.
Although he had gained a favourable reputation during the immediate post-war years, with his funeral becoming a day of national mourning, Haig has, since the 1960s, become an object of criticism for his leadership during the First World War. He was nicknamed "Butcher Haig" for the two million British casualties endured under his command. The Canadian War Museum comments, "His epic but costly offensives at the Somme and Passchendaele have become nearly synonymous with the carnage and futility of First World War battles."
