From the foregoing, however, it would appear that the concentration of WELLINGTON's Army on its own Left, and that of BLÜCHER's Army on its own Right, required longer time than that in which they could have been respectively accomplished on other points; and further that the distribution of the former was better calculated to meet the Enemy's advance by Mons, and that of the latter to meet it by Namur, than to oppose a line of attack by Charleroi. This peculiar feature in the dispositions of the two Commanders did not escape the vigilance of NAPOLEON, who, as will be seen in the sequel, made it subservient to his hopes of beating their Armies in detail. * * * * * The French troops destined to constitute the Grand Army with which NAPOLEON had decided upon taking the field against the allied forces in Belgium, comprised the First, Second, Third, Fourth, and Sixth _Corps d'Armée_; four Corps of Cavalry; and the Imperial Guard: amounting altogether to 116,124 men:-- Infantry 83,753 Cavalry 20,959 Artillery, Waggon-Train, and Engineers 11,412 ------- 116,124 men and 350 guns.

In the beginning of June, this Corps was stationed in and around Lille.
