During the forenoon, however, the troops intended to join Ney were ordered to Marbais on the turnpike,—Lobau[457] at ten o’clock,—the Guard and Milhaud’s cuirassiers at eleven. At noon, it having been reported that the English were still at Quatre Bras, another order[458] was sent to Ney, directing him to attack the enemy there, and informing him that the Emperor was leading the troops now at Marbais to support his operations. Thus the execution of the plan of campaign marked out in the letters to Ney and Grouchy was at last resumed; the reserves under Napoleon marched to join the left wing under Ney; the right wing under Grouchy was assigned to take care of the defeated Prussians. Girard’s division of the 2d Corps, which had suffered severely in the battle,—Girard himself having been mortally hurt,—was left on the field to take care of the wounded. Napoleon had undoubtedly assumed that the Prussian army, if beaten, would retire on its base of operations, towards Namur and Liége. This assumption was strengthened by the circumstances of the battle of Ligny. He had not failed to note the strong force retained by Marshal Blücher to protect his communications with Namur as well as the road to Gembloux, by which the IVth Corps was expected to arrive. He was perfectly justified in inferring that if Blücher had established a new or secondary base at Wavre, for instance, or Louvain, or if he had had any idea whatever of renouncing his line of communications, so as to be able to coöperate with the English in subsequent operations, he would without doubt have placed his left wing in a wholly different position, where he could have made some use of it in the battle.[459] The fact that Thielemann’s Corps was placed where it could not be of any assistance to those of Zieten and Pirch I., seemed to indicate that reliance was placed upon the English for any help these corps might need, and corroborated the presumption that Blücher and Gneisenau were willing to take the risk of the defeat of a part of the Prussian army by accepting battle where support could only be furnished by their allies, and had no intention whatever of renouncing their base of operations, _via_ Namur and Liége. Added to these considerations was the general presumption against such a dangerous and inconvenient course as a change of base must always be.[460] It must also be remembered that the Prussians held the villages of Brye and Sombreffe till after midnight, so that there was no obstacle whatever to the troops of the two beaten corps retiring after the battle by the Quatre-Bras-Namur turnpike towards Namur. It may well be questioned whether there was any need for these troops to cross the pike at all; or whether any of them would have crossed it, had Blücher given orders for the whole army to retire on Namur.[461]
