who commanded the british expeditionary force in world war one
British Expeditionary Force (World War I) The force was commanded by Field Marshal Sir John French until December 1915,[5] when he was replaced by General Sir Douglas Haig.[6] The BEF's Chief of Staff on mobilisation was General Archibald Murray.[7] He was replaced in January 1915 by General William Robertson.[8] Lieutenant-General Launcelot Kiggell then served as Chief of Staff from December 1915 to January 1917 when he was succeeded by Lieutenant-General Herbert Lawrence. The two initial Army Corps were commanded by Douglas Haig (I Corps) and Horace Smith-Dorrien (II Corps).[3]
American Expeditionary Forces The first American troops, who were often called "Doughboys", landed in Europe in June 1917. However the AEF did not participate at the front until October 21, 1917, when the 1st Division fired the first American shell of the war toward German lines, although they participated only on a small scale. A group of regular soldiers and the first American division to arrive in France, entered the trenches near Nancy, France, in Lorraine.[1]
