P.S.—An intercepted letter informs us that the Prussian general Bulow is about to attack our right flank; we think we see the corps on the heights of St.-Lambert; so approach us without losing an instant, and destroy Bulow, should you catch him in the fact.”

The order was in itself no doubt sound and judicious; but the original vice we have already alluded to, as characterizing the movements of the French army after the passage of the Sambre, rendered obedience impossible. The letter, written at one o’clock, did not reach Grouchy until seven, about which time Napoleon’s right had been attacked and driven back by Bulow’s advanced brigades.

It was half-past seven o’clock A.M. on the 18th of June, when Grouchy moved from his bivac at Gembloux, and, owing to the bad state of the roads, nearly half-past eleven, before he reached Sart-lez-Walhain, a distance of about six miles. At the latter place, the report of a heavy cannonade was distinctly heard in the direction of Waterloo: Grouchy was strongly urged by some of his generals to march towards the firing; and for not doing so, he has been attacked at all points. He declined the proposition of his generals, on the ground that he did not consider it his duty to march towards the battle already raging elsewhere, but to attack, according to his instructions, the Prussians with whom he had just come up. Grouchy has since declared, that he did not consider it his duty to follow the advice of Gérard and the other generals, and that to have done so would have been acting contrary to his orders. To have detached a portion of his force towards the main French army would have separated his two corps by the Dyle river, whose waters were much swollen by the heavy rains, and whose banks were so swampy, that it would have been impossible for his divisions to have mutually supported each other; consequently he continued his march upon Wavre.

For argument’s sake, we will suppose that Grouchy adopts the advice of his generals, and commences his march at the time the firing was first heard, about half-past twelve o’clock. On average roads in fair condition, an army of thirty-two thousand men of all arms would take seven hours to march fifteen miles; they had already marched about six miles, as we have seen, over bad roads. From Sart-lez-Walhain to Plancenoit, Napoleon’s right, the distance is about sixteen miles, and over bad roads; how could they have come up in time, and that, without taking into account the obstructions which they must have encountered from the Prussian corps who were scouring the whole of that part of the country? It was utterly impossible for Grouchy, after breaking up his bivac at Gembloux so late as half-past seven o’clock on the morning of the 18th, to prevent the three Prussian corps, who well knew his movements, from forming a junction with us, or from attacking the French right. Had Grouchy left Gembloux at two o’clock A.M., and marched, unmolested by the Prussians, by St.-Guibert and Moustier to St.-Lambert, and taken position near the defiles of the Lasne and St.-Lambert, he might have kept Bulow from attacking the French right, and Napoleon might, before eight o’clock, about which time a brigade of Pirch’s and part of a brigade of Zieten’s corps came up, have attacked Wellington with his whole remaining force.

After the unaccountable delay on the 17th, the division of his force by Napoleon appears a false move; for a corps of cavalry would have sufficed to watch the Prussians. Grouchy, unquestionably, was dilatory, and wanting in his former energy and judgment; for though he must have known that the Prussians, or a large portion of them, would attempt their junction with us, he sent out no patrols to ascertain whether the contemplated movement was in operation, and neglected to keep up that which is always so essential, a close communication with the main body of the French army. His whole attention appears to have been directed to his right; the events on his left he entirely neglected.

We have stated Napoleon’s anxiety to impute the blame of the failure exclusively to his two marshals. We have endeavoured, in the fair and fearless spirit of military criticism, to examine how far such inculpation is borne out by facts in the case of marshal Grouchy, and we now, in the same impartial manner, propose to analyze the accusation made against the gallant and daring Ney, “the bravest of the brave.” The charges are twofold: delay at Quatre-Bras, and rashness at Waterloo.

Ney, as we have seen, had been ordered by Napoleon, on the morning of the 16th, to seize Quatre-Bras, to occupy Genappe if practicable, and to be ready to march on Brussels the same evening, (16th,) or on the morning of the 17th at latest, as the seizure of the capital by a coup de main on the 17th was the Emperor’s grand object. For this purpose Ney was, if possible, to press forward three or four leagues at least, on the 16th, and to be supported by the light cavalry of the Imperial guard.

Now, Ney is blamed by Napoleon and other military writers (French,) for not having gained possession of Quatre-Bras early on the 16th, before our force came up. Certainly no British soldier underrates the value of an early attack: (as Aroyo-de-Molinos can testify:) but was Ney justified in attempting to obtain possession of Quatre-Bras? We incline to think he was not. More than one half of his force was still in the rear: D’Erlon’s corps was on the Sambre, or close to it, Girard’s division of Reille’s corps was near Fleurus with Grouchy, and Kellermann’s cavalry had not joined. No blame to him, the gallant Ney, for that; he had joined the army but the evening before, (the 15th). Notwithstanding these untoward events, he ordered forward Reille’s (second) corps; but finding that heavy masses of the enemy were concentrating at St.-Amand on his right, and ignorant of the force in his front, he judiciously declined to press on till D’Erlon came up as a support.

Napoleon, before he left Charleroi, sent another order to Ney to unite his force, (Reille’s and D’Erlon’s corps, and Kellermann’s cuirassiers who were about to join him,) remarking, “With this force you ought to overwhelm any strength the enemy may oppose to you.” When Ney commenced his attack on Quatre-Bras he was cautious. Napoleon had now arrived at Fleurus, and sent word to Ney, that Grouchy would attack the Prussians at half-past two o’clock; that he, Ney, was to press vigorously upon any enemy in his front, and then turn round and assist in crushing the Prussians at Ligny. About three o’clock, Ney got another dispatch, informing him that the battle of Ligny had already begun, directing him to manœuvre immediately, so as to fall upon the Prussian rear with all his force, which would be utterly destroyed if he acted with vigour, adding, in his own emphatic language addressed to a heart so susceptible and patriotic as Ney’s, “The fate of France is in your hands!” But that which pre-eminently characterized Napoleon’s early career, that to which he almost exclusively owed his brilliant victories, that in which all men of all nations will admit his wonderful excellence,—rapidity in executing his plans,—here again failed him. Lightning may slumber; but Time will ceaselessly march on, heedless of the errors of heroes! The Emperor’s delay enabled our noble Picton, with his gallant band, to come up from Brussels, closely followed by the Brunswickers, headed by their cherished and chivalrous duke, who found Quatre-Bras to be his last battle field. Such foes occupied Ney: and Napoleon knew it not!

Observe, Napoleon (who, according to French historians, could not err,) intrusting the fate of France to a flank movement by Ney, who was unable ultimately to hold his own position! He accuses Ney of having kept Reille’s and D’Erlon’s corps detached, saying, “Had he united them, not an Englishman would have escaped at Quatre-Bras;” and yet it was by Napoleon’s own order, (in a pencilled note,) conveyed by colonel Laurent, that Ney was ordered to detach D’Erlon’s corps to St.-Amand! Laurent, falling in with the head of the column then marching on Frasnes, upon his own responsibility changed its direction. On inquiring for count D’Erlon, he was informed that, as was his habit, he had gone ahead to Frasnes, preceding his column. On his arrival at the latter place, Laurent found the general, and handed over to him the pencilled note, stating, at the same time, the position in which he might find the head of his column.
