“3dly.—The horse grenadiers and the dragoons of the guard, under the command of General Guyot, engaged without orders. Thus, at five in the afternoon, the army found itself without a reserve of cavalry. If, at half past eight, that reserve had existed, the storm which swept all before it on the field of battle would have been dispersed, the enemy’s charges of cavalry driven back, and the two armies would have slept on the field, notwithstanding the successive arrivals of General Bulow and Marshal Blucher: the advantage would also have been in favour of the French army, as Marshal Grouchy’s 34,000 men, with 108 pieces of cannon, were fresh troops and bivouacked on the field of battle. The enemy’s two armies would have placed themselves in the night under cover of the forest of Soignes. The constant practice in every battle was for the horse-grenadiers and the dragoons of the guard never to lose sight of the Emperor, and never to make a charge but in consequence of an order verbally given by that Prince to the General who commanded them.
“Marshal Mortier, who was Commander in Chief of the guards, gave up the command on the 15th, at Beaumont, just as hostilities were on the point of commencing, and no one was appointed in his stead, which was attended with several inconvenient results.
Sixth Observation.—“1st, The French army manœuvred on the right of the Sambre, on the 13th and 14th. It encamped, the night between the 14th and 15th, within half a league of the Prussian advanced posts; and yet Marshal Blucher had no knowledge of it, and when, on the morning of the 15th, he learned at his head-quarters at Namur that the Emperor had entered Charleroi, the Prusso-Saxon army was still cantoned over an extent of thirty leagues; two days were necessary for him to effect the junction of his troops. It was his duty, from the 15th of May, to advance his head-quarters to Fleurus, to concentrate the cantonments of his army within a radius of eight leagues, with his advanced posts on the Meuse and Sambre. His army might then have been assembled at Ligny on the 15th at noon, to await in that position the attack of the French army, or to march against it in the evening of the 15th, for the purpose of driving it into the Sambre.
“2dly.—Yet, notwithstanding this surprise of Marshal Blucher, he persisted in the project of collecting his troops on the heights of Ligny, behind Fleurus, exposing himself to the hazard of being attacked before the arrival of his army. On the morning of the 16th, he had collected but two corps, and the French army was already at Fleurus. The third corps joined in the course of the day, but the fourth, commanded by General Bulow, was unable to get up in time for the battle. Marshal Blucher, the instant he learned the arrival of the French at Charleroi, that is to say, on the evening of the 15th, ought to have assigned, as a point of junction for his troops, neither Fleurus nor Ligny, which were under the enemy’s cannon, but Wavres, which the French could not have reached until the 17th. He would have also had the whole of the 16th, and the night between the 16th and 17th, to effect the total junction of his army.
“3dly.—After having lost the battle of Ligny, the Prussian General, instead of making his retreat on Wavres, ought to have effected it upon the army of the Duke of Wellington, whether at Quatre-Bras, where the latter had maintained himself, or at Waterloo. The whole of Marshal Blucher’s retreat on the morning of the 17th was contrary to common sense, since the two armies, which were, on the evening of the 16th, little more than three miles from each other, and had a fine road for their point of communication, in consequence of which their junction might have been considered as effected, found themselves, on the evening of the 17th, separated by a distance of nearly twelve miles, and by defiles and impassable ways.
“The Prussian General violated the three grand rules of war; 1st, To keep his cantonments near each other; 2dly, To assign as a point of junction a place where his troops can all assemble before those of the enemy; 3dly, To make his retreat upon his reinforcements.
Seventh Observation.—“1st, The Duke of Wellington was surprised in his cantonments; he ought to have concentrated them on the 15th of May, at eight leagues about Brussels, and kept advanced guards on the roads from Flanders. The French army was for three days manœuvring close upon his advanced posts; it had commenced hostilities twenty four hours, and its head-quarters had been twelve hours at Charleroi, and yet the English General was at Brussels, ignorant of what was passing, and all the cantonments of his army were still in full security, extended over a space of more than twenty leagues.
“2dly.—The Prince of Saxe-Weimar, who belonged to the Anglo-Dutch army, was, on the 16th, at four o’clock in the afternoon in position before Frasne, and knew that the French army was at Charleroi. If he had immediately despatched an aide-de-camp to Brussels, he would have arrived there at six in the evening; and yet the Duke of Wellington was not informed that the French army was at Charleroi until eleven at night. He thus lost five hours, in a crisis, and against a man, that rendered the loss of a single hour highly important.
“3dly.—The infantry, cavalry, and artillery of that army were in cantonments, so remote from each other that the infantry was engaged at Waterloo without cavalry or artillery, which exposed it to considerable loss, since it was obliged to form in close columns to make head against the charges of the cuirassiers, under the fire of fifty pieces of cannon. These brave men were slaughtered without cavalry to protect or artillery to avenge them. As the three branches of an army cannot, for an instant, dispense with each other’s assistance, they should be always cantoned and placed in such a way as to be able to assist each other.
“4th.—The English General, although surprised, assigned Quatre-Bras, which had been, for the last four-and-twenty[four-and-twenty] hours in possession of the French, as the rallying point of his army. He exposed his troops to partial defeats as they gradually arrived; the danger which they incurred was still more considerable, since they came without artillery and without cavalry; he delivered up his infantry to his enemy piece-meal, and destitute of the assistance of the two other branches. He should have fixed upon Waterloo for his point of junction; he would then have had the day of the 16th, and the night between the 16th and 17th, an interval quite sufficient, to collect the whole of his army, infantry, cavalry, and artillery. The French could not have arrived until the 17th, and would have found all his troops in position.
