The Expeditionary Force was commanded by Field Marshal Sir John French, and consisted, up to August 23, of four complete divisions of infantry (the First, Second, Third, and Fifth) and five brigades of cavalry; that is to say, about 80,000 men. On August 24 it was joined by the Nineteenth Infantry Brigade, which added 4000 more; and on August 25 by the Fourth Division, which added another 17,000. Our total strength, therefore, during the fighting at Mons and in the Retreat, varied from 80,000 to a little over 100,000 men. It was a small force, but of a quality rarely seen. No finer fighting unit ever entered the field. In physique and equipment, in professional training and experience of war, in that quality of skilful and cheerful tenacity against odds which distinguishes the veteran, it was probably unrivalled by any body of troops of its time. The French, who gave our men a warm welcome, dwell always on their youth and good spirits, their wonderful cleanness and healthiness, the excellence of their equipment, and their universal courtesy. "À Argenteuil-Triage," writes a French infantryman who fought in the Retreat and on the Marne, "nous croisons un train de fantassins anglais; figures rasées, ouvertes, enfantines, riant de toutes leurs dents. Ils sont reluisants de propreté. Nous nous acclamons réciproquement." (Sept. 2/14: Garnet de Route; Roujons.) At Bucy-le-long the French relieve the English. It is a matter of outposts. "De deux cents mètres en deux cents mètres, un groupe de six Anglais est couché à plat ventre dans les betteraves, en bordure d’un chemin. Ils se dressent et nous allons prendre leurs places en admirant ces beaux soldats, bien équipés, silencieux, et qui ont des couvertures." (_Ibid._, Oct. 6/14.) Such opinions were worth much. For though it is a great thing to be welcomed, as our men were welcomed, by a whole people, to have the hearty professional approval of its soldiers is a greater thing still. The Expeditionary Force, thus landed in France, was organized in two army corps--the First, consisting of the First and Second Divisions, under Lieutenant-General Sir Douglas Haig; the second, consisting of the Third and Fifth Divisions, under Lieutenant-General Sir James Grierson, who was succeeded, on his sudden and much lamented death, by General Sir Horace Smith-Dorrien. General Allenby commanded the cavalry division, consisting of the First, Second, Third, and Fourth Cavalry Brigades, and the Fifth Cavalry Brigade was commanded independently by Brigadier-General Sir Philip Chetwode. By the evening of Friday, August 21, the concentration was practically complete, and during Saturday the 22d the Force moved up to its position on the left or western extremity of the French line.
