Mr. Ropes considers that on the morning of the 17th Napoleon had thus far in the main fulfilled his programme. This view may be questioned. He had merely defeated two of the four Prussian corps; he had not wrecked Blücher. He had failed to occupy Quatre Bras; the Anglo-Dutch army had succeeded in effecting a partial concentration and in repulsing his left wing there. Still it must be admitted that with two corps absolutely intact and with no serious losses in the Guard and cavalry, Napoleon was in good shape for carrying out his plan. If Ney had sent him word overnight that Wellington's army was bivouacking about Quatre Bras in ignorance, as it turned out, of the result of Ligny, he might have attacked it to good purpose in conjunction with Ney in the early morning of the 17th. But Ney was silent and sulky; Napoleon himself was greatly fatigued, and Soult was of no service to him. During the night the Prussians "had folded their tents like the Arabs, and as silently stolen away." They had neither been watched nor followed up, all touch of them had been lost, and there was nothing to indicate their line of retreat. This slovenliness on the part of the French would not have occurred in Napoleon's earlier days; nor in those days of greater vigour would he have delayed until after midday of the 17th to follow up an army which he had defeated on the previous evening, and which had disappeared from before him in the course of the night. The reports which had been sent in from a cavalry reconnaissance despatched in the morning indicated that the Prussians were retiring on Namur. No reconnaissance had been made in the direction of Tilly and Wavre. This was a strange error, since Blücher had two corps still untouched, and as above everything a fighting man, was not likely to throw up his hands and forsake his ally after one partial discomfiture. Napoleon tardily determined to despatch Grouchy on the errand of following up the Prussians with a force consisting of about 33,000 men with ninety-six guns. Thus far all authorities are agreed; but as regards the character of the orders given to Grouchy for his guidance in an obviously somewhat complicated enterprise, there is an extraordinary contrariety of evidence. It is stated in the _St. Helena Memoirs_ that Grouchy received positive orders to keep himself always between the main French army and Blücher; to maintain constant communication with the former and in a position easily to rejoin it; that since it was possible that Blücher might retreat on Wavre, he (Grouchy) was to be there simultaneously; if the Prussians should continue their march on Brussels and should pass the night in the forest of Soignies, he was to follow to the edge of the forest; should they retire on the Meuse, he was to watch them with part of his cavalry and himself occupy Wavre with the mass of his force, where he should be in position for easy communication with Napoleon's headquarters.
