5 under von Kluck (First German Army), attacking British. 4 under von Buelow (Second German Army), attacking 5th French Army. 4 under von Hausen (Third German Army), attacking 4th French Army. The general lines of advance will be seen in plan A (page 71) and plan B (page 98). Thus, the total German force concentrated on or about this immediate front must have numbered at least 812,500, with, say, 3,010 field-guns and 936 machine-guns. It is not unreasonable to add to this total the not inconsiderable number of cavalry which operated, more or less independently, on the extreme flanks, and particularly from Tournai down through Amiens towards Le Havre. _The French Forces_ The total strength, all ranks, of a French Army Corps is, roughly, 40,000, with, say, 160 field- and 48 machine-guns. In this area there were present 3 corps under Lanrezac (5th French Army) holding the line Charleroi-Namur, and 3 corps under de Langle de Gary (4th French Army) holding a line west of the River Meuse south-west from Namur. Away on the left flank of the British was another Corps, of Territorials, under d'Amade; and near Maubeuge, in reserve, were two or three Cavalry Divisions. These last did not, I believe, operate; and the Territorials were also fully occupied in their own area. Reckoning up, then, we get an approximate total of, say, 240,000 men, 960 field- and 288 machine-guns. _The British Forces_ A British Army Corps, of two Divisions, contains about 36,145, all ranks, with 152 field- and 48 machine-guns. A Cavalry Division contains about 9,270, all ranks, with 24 field- and 24 machine-guns; a Cavalry Brigade about 2,285, all ranks, 6 field- and 6 machine-guns. This is not revealing State secrets, because the numbers may be obtained from any military reference books. Now it was, I believe, originally intended that the Expeditionary Force should be about 120,000 strong, or half the strength of the army with the colours. The force actually present at Mons on August 22nd consisted, nominally, of two Army Corps, a Cavalry Division and a Cavalry Brigade. But several authorities, including Mr. Hilaire Belloc, assert that one of these corps was considerably below strength, and that, in round numbers, the strength of the Force was no more than 75,000, with 250 guns. If we calculate up the _official_ strength the numbers should work out at 83,845 all ranks, 334 field- and 126 machine-guns. Another Infantry Brigade came up on the 23rd and joined the Second Corps, and another Division (the 4th) also arrived.[1] Taking everything into account it is, I think, reasonable to put the British strength at about 80,000 men, 300 field- and 100 machine-guns when battle was first joined. Let me put these figures in tabular form so that we can get a comparison at a glance. _Machine-_ _All ranks. Field-guns. guns._ _Actual Approximate Numbers on August_ 22_nd_
