Napoleon sent an Order to Ney to renew the attack upon the Centre. To execute this with effect, however, fresh Infantry was requisite; and the Marshal had none at his disposal. He therefore despatched his first Aide de Camp, Colonel Heymès, to represent to the Emperor the exhausted condition of his troops: half of which were placed hors de combat, and the other half overcome by fatigue, and failing in ammunition; and to request he would send him reinforcements. At this moment, however, Lobau's Corps and the Young Guard were required for the security of the French Right Flank against the offensive operations of the Prussians; consequently, the Battalions of the Old Guard, which constituted the only remaining Reserve of Infantry, could not be spared. To Ney's demand for fresh troops, Napoleon therefore replied,—"Ou voulez vous que j'en prenne? Voulez vous que j'en fusse?"

Ney, on being made acquainted with the manner in which his request had been received, saw very plainly that the Battle was far from being gained: and darted off to animate, by his presence, the attack which was now renewed upon La Haye Sainte; and which was covered by a vigorous fire from the French Artillery against that portion of the Anglo-Allied Line immediately in rear of this Post, in order to disturb any attempt to relieve or assist its defenders.

The united remains of Somerset's and Ponsonby's Brigades, which were on the reverse slope, behind Ompteda's Brigade of the King's German Legion, and which were extended in Single File for the purpose of making a show of force, suffered much from this cannonade. On perceiving its effects, Lord Uxbridge sent an Aide de Camp to recommend Lord Edward Somerset to withdraw his men from the range of the Enemy's guns. The latter sent back word that, were he to do so, the Dutch-Belgian Cavalry, who were in support, would immediately move off the Field! Somerset retained his position until the end of the Battle.

Shortly before the Columns from Donzelot's Division advanced to this attack of La Haye Sainte, a party of Horse Artillery, which had been detached from Whinyates's Rocket Battery, proceeded, under Captain Dansey, along the Charleroi road, to the front of the Centre of the Anglo-Allied Line, and came into action with rockets, near that Farm, leaving its two guns in the rear, under Lieutenant Wright.

Captain Dansey very soon received a severe wound, which obliged him to retire; and the party, after firing a few rockets, fell back a little, to where its horses were standing. It was then commanded by a Serjeant (Daniel Dunnett), who, on perceiving the advance of the nearest French Column towards the Farm, dismounted his men as coolly and deliberately as if exercising on Woolwich Common, though without any Support whatever; laid rockets on the ground, and discharged them in succession into the mass—every one of them appearing to take effect. The advance of the Column was checked, and was not resumed until Sergeant Dunnett, having expended all his rockets, retired with his party to rejoin the guns in rear.

Major Baring's Detachment, after its extraordinary and successful exertions in repelling the previous assaults, was fearfully reduced in numbers; but its excellent spirit and conspicuous bravery remained unshaken. One circumstance, however, could not fail to render unavailing all their efforts, their courage, and their endurance. Notwithstanding Major Baring's urgently repeated applications for a supply of ammunition, his men were still left without the means of adequately defending their Post against the host of enemies by which they were successively assailed.[12] They cheerfully repaired, as far as practicable, the gaps made in the walls by the French Artillery, and betrayed no despondency as they looked upon the sad and numerous proofs that lay around them of the immense sacrifices they had already made. But when, upon counting the cartridges, they discovered that they had not, upon an average, more than from three to four each, their consciousness of the desperate situation to which they were reduced, and of the impossibility of holding out under such circumstances, led to remonstrances, which their gallant Commander could not but admit to be reasonable. Yet no sooner did the latter, upon perceiving two French Columns again advancing towards the Farm, exhort them to renewed courage, and also to a careful economy of the ammunition, than he received the unanimous reply,—"No man will desert you,—we will fight and die with you!"

The French, exasperated by the protracted resistance of this handful of brave defenders, now came on with redoubled fury. The open end of the Great Barn was first assailed. Again they succeeded in setting the building on fire; but the Germans, having recourse to the same expedient as on the previous occasion, again contrived to extinguish the flames. Baring's anxiety and uneasiness increased with every shot that was fired by his men; and he again sent to the rear for ammunition, coupling his demand with a distinct report, that he must and would abandon the place should no supply be forthcoming. This message, however, proved equally ineffectual. The fire of the garrison was gradually diminishing: perplexity was depicted in every countenance: many of the men now called out urgently for ammunition,—"We will readily stand by you, but we must have the means of defending ourselves!" Even their Officers, who during the whole day had displayed the greatest courage, represented to their Commander the impossibility of retaining the Post under such circumstances.

The French, who failed not to observe the distressing situation to which the defenders were reduced, now boldly broke in the door at that end of the long western building which is nearest to the entrance of the Great Barn, already so frequently assailed. The passage from the door through the building into the Farm yard having been barricaded, but few of the Enemy could enter at a time. These were instantly bayoneted, and the rear hesitated to follow. They now climbed up the outer wall of the long building, and mounted the roof, from which they easily picked off the defenders; who, not possessing the means of retaliation, were completely at their mercy. At the same time, they pressed in through the open Barn, which it was impossible to defend any longer. Baring was now reduced to the painful necessity of abandoning the place, and gave the Order to retire through the Dwelling House into the Garden. Many of the men were overtaken in the narrow passage through the House by the victors, who vented their fury upon them in the lowest abuse and most brutal treatment.

Baring having satisfied himself that the possession of the Dwelling House by the Enemy must render the Garden quite untenable; and finding that his Officers fully agreed with him on this point, he made the men retire, singly, to the main position. The greater part of them, accompanied by their brave but disconsolate Commander, descended into the high road by an opening in the bank adjoining the north-east angle of the Garden, and retired along the opposite side of the chaussée.
