The old division of General Gérard was left at Fleurus.
The Emperor, with his staff, took his station on a little knap, near the farm of La Belle Alliance, which commanded the plain, and whence he could easily direct the movements of the army, and observe those of the English.
At half after twelve, the Emperor, persuaded that Marshal Grouchy must be in motion, caused the signal for battle to be given.
Prince Jerome, with his division, proceeded against Hougoumont. The approaches were defended by hedges and a wood; in which the enemy had posted a number of artillery. The attack, rendered so difficult by the state of the ground, was conducted with extreme impetuosity. The wood was alternately taken and retaken. Our troops and the English, most frequently separated by a single hedge, fired on each other reciprocally, their muskets almost touching, without retreating a single step. The artillery made fearful ravages on both sides. The event was doubtful, till General Reille ordered Foy's division to support the attack of Prince Jerome, and thus succeeded in compelling the enemy, to abandon the woods and orchards, which they had hitherto so valiantly defended and kept possession of.
It was one o'clock. A few moments before, an intercepted despatch informed the Emperor of the near approach of thirty thousand Prussians, commanded by Bulow[49].
Napoleon thought, that the strength of this corps, some of the skirmishers of which had appeared on the heights of St. Lambert, was exaggerated; and persuaded too, that Grouchy's army was following it, and that it would soon find itself between two fires, it gave him but little uneasiness. However, rather from precaution than from fear, he gave orders to General Domont, to advance with his cavalry and that of General Suberwick, to meet the Prussians and directed Count de Lobau, to be ready to support General Domont in case of necessity. Orders were despatched at the same time to Marshal Grouchy, to inform him of what was passing, and enjoin him anew, to hasten his march, to pursue, attack, and crush Bulow.
Thus by drawing off the divisions of Domont and Suberwick, and by the paralyzation of the 6th corps, our army was reduced to less than fifty-seven thousand men: but it displayed so much resolution, that the Emperor did not doubt its being sufficient, to beat the English.
The second corps, as I have already said, had effected the dislodgment of the English from the woods of Hougoumont; but the first corps, notwithstanding the continual play of several batteries, and the resolution of our infantry and of the light horse of General Lefevre Desnouettes and Guyot, had been unable to force either La Haie Sainte, or Mont St. Jean. The Emperor ordered Marshal Ney, to undertake a fresh attack, and to support it by eighty pieces of cannon. A tremendous fire of musketry and artillery then took place throughout the whole line. The English, insensible to danger, supported the charges of our foot and of our horse with great firmness. The more resistance they displayed, the more furiously did our soldiers engage. At length the English, driven from one position to another, evacuated La Haie Sainte and Mont St. Jean, and our troops seized on them with shouts of "Long live the Emperor!"
To sustain them there, Count d'Erlon immediately sent the second brigade of General Alix. A body of English horse intercepted the passage, threw the brigade into disorder, and then, falling on our batteries, succeeded in dismounting several pieces of artillery. The cuirassiers of General Milhaud set off at a gallop, to repulse the English horse. A fresh division of these came and fell upon our cuirassiers. Our lancers and chasseurs were sent to their assistance. A general charge ensued, and the English, broken, overthrown, cut down, were forced to retire in disorder.
Hitherto the French army, or, to speak more properly, the forty thousand men of Generals Reille and d'Erlon, had obtained and preserved a marked superiority. The enemy, driven back, appeared hesitating on their movements. Dispositions had been observed, that seemed to indicate an approaching retreat. The Emperor, satisfied, joyfully exclaimed: "They are ours: I have them:" and Marshal Soult, and all the generals, considered, as he did, the victory certain[50]. The guard had already received orders to put itself in motion, to occupy the ground we had gained, and finish the enemy, when General Domont sent to inform the Emperor, that Bulow's corps had just formed in line, and was advancing rapidly on the rear of our right. This information changed the design of Napoleon; and, instead of employing his guard to support the first and second corps, he kept it in reserve; ordering Marshal Ney to maintain his ground in the woods of Hougoumont, at La Haie Sainte, and at Mont St. Jean, till the event of the movement, which Count Lobau was about to make against the Prussians, was known.
