Hearing that matters were in this precarious state on the left, Marlborough galloped from the right centre, accompanied by his staff, where Lotturn's infantry and D'Auvergne's horse had gained such important advantages. Matters erelong became so alarming, that Eugene also followed in the same direction. On his way along the rear of the line, the English general had a painful proof of the enthusiastic spirit with which his troops were animated, by seeing numbers of the wounded Dutch and Hanoverians, whose hurts had just been bound up by the surgeons, again hastening to the front, to join their comrades, though some, faint from the loss of blood, yet tottered under the weight of their muskets. The reserves were hastily directed to the menaced front, and by their aid the combat was in some degree restored in that quarter; while Marlborough and Eugene laboured to persuade the Prince of Orange, who was burning with anxiety at all hazards to renew the attack, that his operations were only intended as a feint, and that the real effort was to be made on the right, where considerable progress had already been made. Order was hardly restored in this quarter, when intelligence arrived from the right that the enemy were assuming the initiative in the wood of Taisnière, and were pressing hard both upon the troops at La Folie and in front of the wood. In fact, Villars, alarmed at the progress of the enemy on his left in the wood, had drawn considerable reinforcements from his centre, and sent them to the threatened quarter. Marlborough instantly saw the advantage which this weakening of the enemy's centre was likely to give him. While he hastened back, therefore, with all imaginable expedition to the right, to arrest the progress of the enemy in that quarter, he directed Lord Orkney to advance, supported by a powerful body of horse on each flank, directly in at the opening between the two woods, and if possible force the enemy's intrenchments in the centre, now stripped of their principal defenders.

These dispositions, adopted on the spur of the moment, and instantly acted upon, proved entirely successful. Eugene galloped to the extreme right, and renewed the attack with Schulemberg's men, while Withers again pressed on the rear of the wood near La Folie. So vigorous was the onset, that the Allies gained ground on both sides of the wood, and Villars hastening up with the French guards to restore the combat near La Folie, received a wound in the knee, when gallantly heading a charge of bayonets, which obliged him to quit the field. In the centre, still more decisive advantages were gained. Lord Orkney there made the attack with such vigour, that the intrenchments, now not adequately manned, were at once carried; and the horse, following rapidly on the traces of the foot soldiers, broke through at several openings made by the artillery, and spread themselves over the plain, cutting down in every direction. The grand battery of forty cannon in the allied centre received orders to advance. In the twinkling of an eye the guns were limbered up, and moving on at a quick trot. They soon passed the intrenchments in the centre, and facing to the right and left, opened a tremendous fire of canister and grape on the dense masses of the French cavalry which there stood in the rear of the infantry, who were almost all in front among the works. These noble troops, however, bore up gallantly against the storm, and even charged the allied horse before they had time to form within the lines; but they were unable to make any impression, and retired from the attack sorely shattered by the allied artillery.

The battle was now gained. Villars' position, how strong and gallantly defended soever, was no longer tenable. Pierced through in the centre, with a formidable enemy's battery thundering on either side, in the very heart of his line, on the reserve squadrons, turned and menaced with rout on the left, it was no longer possible to keep the field. Boufflers, upon whom, in the absence of Villars in consequence of his wound, the direction of affairs had devolved, accordingly prepared for a retreat; and he conducted it with consummate skill, as well as the most undaunted firmness. Collecting a body of two thousand chosen horse yet fresh, consisting of the élite of the horse-guards and garde-du-corps, he charged the allied horse which had penetrated into the centre, and was by this time much blown by its severe fatigues in the preceding part of the day. It was accordingly worsted and put to flight; but all the efforts of this noble body of horsemen were shattered against Orkney's infantry, which, posted on the reverse of the works they had won, poured in, when charged, so close and destructive a fire, as stretched half of the gallant cavaliers on the plain, and forced the remainder to a precipitate retreat. Still the indefatigable Boufflers made another effort. Drawing a large body of infantry from the works on his extreme right, which had been little engaged, he marched them to the left, and reforming his squadrons again, advanced to the charge. But Marlborough no sooner saw this, than he charged the garde-du-corps with a body of English horse which he himself led on, and drove them back, while the infantry staggered and reeled like a sinking ship under the terrific fire of the allied guns, which had penetrated the centre. At the same time the Prince of Orange and the Prince of Hesse-Cassel, perceiving that the intrenchments before them were stript of great part of their defenders, renewed the attack; in ten minutes these works were carried; a tremendous shout, heard along the whole line, announced that the whole left of the position had fallen into the hands of the Allies.

In these desperate circumstances, Boufflers and his brave troops did all that skill or courage could suggest to arrest the progress of the victors, and withdraw from the field without any additional losses. Forming his troops into three great masses, with the cavalry which had suffered least in rear, he slowly, and in perfect regularity, commenced his retreat. The Allies had suffered so much, and were so completely exhausted by the fatigue of this bloody and protracted battle, that they gave them very little molestation. Contenting themselves with pursuing as far as the heath of Malplaquet, and the level ground around Taisnière, they halted, and the men lay down to sleep. Meanwhile the French, in the best order, but in deep dejection, continued their retreat still in three columns; and after crossing the Hon in their rear, reunited below Quesnoy and Valenciennes, about twelve miles from the field of battle.[39]

Such was the desperate battle of Malplaquet, the most bloody and obstinately contested which had yet occurred in the war, and in which it is hard to say to which of the gallant antagonists the palm of valour and heroism is to be given. The victory was unquestionably gained by the Allies, since they forced the enemy's position, drove them to a considerable distance from the field of battle, and hindered the siege of Mons, the object for which both parties fought, from being raised. The valour they displayed had extorted the admiration of their gallant and generous enemies.[40] On the other hand, these advantages had been purchased at an enormous sacrifice, and never since the commencement of the contest had the scales hung so even between the contending parties. The Allies lost, killed in the infantry alone, five thousand five hundred and forty-four; wounded and missing, twelve thousand seven hundred and six; in all eighteen thousand two hundred and fifty, of whom two hundred and eighty-six were officers killed, and seven hundred and sixty-two wounded. Including the casualties in the cavalry and artillery, their total loss was not less than twenty thousand men, or nearly a fifth of the number engaged. The French loss, though they were worsted in the fight, was less considerable; it did not exceed fourteen thousand men—an unusual circumstance with a beaten army, but easily accounted for, if the formidable nature of the intrenchments which the Allies had to storm in the first part of the action, is taken into consideration. In proportion to the numbers engaged, the loss to the victors was not, however, nearly so great as at Waterloo.[41] Few prisoners, not above five hundred, were made on the field; but the woods and intrenchments were filled with wounded French, whom Marlborough, with characteristic humanity, proposed to Villars to remove to the French headquarters, on condition of their being considered prisoners of war—an offer which that general thankfully accepted. A solemn thanksgiving was read in all the regiments of the army two days after the battle, after which the soldiers of both armies joined in removing the wounded French on two hundred waggons to the French camp. Thus, after the conclusion of one of the bloodiest fights recorded in modern history, the first acts of the victors were in raising the voice of thanksgiving, and doing deeds of mercy.[42]

No sooner were these pious cares concluded, than the Allies resumed the investment of Mons: Marlborough, with the English and Dutch, having his headquarters at Belian, and Eugene, with the Germans, at Quaregnon. The Prince of Orange, with thirty battalions and as many squadrons, was intrusted with the blockade. Great efforts were immediately made to get the necessary siege equipage and stores up from Brussels; but the heavy rains of autumn set in with such severity, that it was not till the 25th September that the trenches could be opened. Boufflers, though at no great distance, did not venture to disturb the operations. On 9th October, a lodgement was effected in the covered way; on the 17th, the outworks were stormed; and on the 26th, the place surrendered with its garrison, still three thousand five hundred strong. By this important success, the conquest of Brabant was finished; the burden and expense of the war removed from the Dutch provinces; the barrier which they had so long sought after was rendered nearly complete; and the defences of France were so far laid bare, that by the reduction of Valenciennes and Quesnoy, in the next campaign, no fortified place would remain between the Allies and Paris. Having achieved this important success, the allied generals put their army into winter-quarters at Ghent, Bruges, Brussels, and on the Meuse; while fifty battalions of the French, with one hundred squadrons, were quartered, under the command of the Duke of Berwick, in the neighbourhood of Maubeuge, and the remainder of their great army in and around Valenciennes and Quesnoy.[43]

During the progress of this short but brilliant campaign, Marlborough was more than ever annoyed and disheartened by the evident and increasing decline of his influence at home. Harley and Mrs Masham contrived to thwart him in every way in their power; and scarcely disguised their desire to make the situation of the Duke and Godolphin so uncomfortable, that out of spleen they might resign; in which case, the entire direction of affairs would have fallen into their hands.[44] Influenced by these new favourites, the Queen became cold and resentful to the Duchess of Marlborough, to whom she had formerly been so much attached; and the Duke, perceiving this, strongly advised her to abstain from any correspondence with her Majesty, as more likely to increase than diminish the estrangement so rapidly growing between them. The Duchess, however, was herself of too irritable a temper to follow this sage advice; reproaches, explanations, and renewed complaints ensued on both sides; and as usual in such cases, where excessive fondness has been succeeded by coldness, all attempts to repair the breach only had the effect of widening it. Numerous events at court, trifles in themselves, but "confirmation strong" to the jealous, served to show in what direction the wind was setting. The Duchess took the strong and injudicious step of intruding herself on the Queen, and asking what crime she had committed to produce so great an estrangement between them. This drew from her Majesty a letter, exculpating her from any fault, but ascribing their alienation to a discordance in political opinion, adding, "I do not think it a crime in any one not to be of my mind, or blamable, because you cannot see with my eyes, or hear with my ears." While this relieved Marlborough from the dread of a personal quarrel between the Duchess and Royalty, it only aggravated the precarious nature of his situation, by showing that the split was owing to the wider and more irremediable division on political subjects.[45]

Encouraged by this powerful support at court, Harley now openly pursued his design of effecting the downfall of Marlborough, and his removal from office, and the command of the armies. The whole campaign which had terminated so gloriously, was criticised in the most unjust and malignant spirit. The siege of Tournay was useless and expensive; the battle of Malplaquet an unnecessary carnage. It was even insinuated the Duke had purposely exposed the officers to slaughter, that he might obtain a profit by the sale of their commissions. The preliminaries first agreed to at the Hague were too favourable to France; when Louis rejected them, the rupture of the negotiations rested with Marlborough. In a word, there was nothing done by the English general, successful or unsuccessful, pacific or warlike, which was not made the subject of loud condemnation, and unmeasured invective. Harley even corresponded with the disaffected party in Holland, in order to induce them to cut short the Duke's career of victory by clamouring for a general peace. Louis was represented as invincible, and rising stronger from every defeat: the prolongation of the war was entirely owing to the selfish interests and ambition of the allied chief. These and similar accusations, loudly re-echoed by all the Tories, and sedulously poured into the royal ear by Harley and Mrs Masham, made such an impression on the Queen, that she did not offer the smallest congratulation to the Duchess on the victory of Malplaquet, nor express the least satisfaction at the Duke's escape from the innumerable dangers which he had incurred.[46]

An ill-timed and injudicious step of Marlborough at this juncture, one of the few which can be imputed to him in his whole public career, inflamed the jealousy of the Queen and the Tories at him. Perceiving the decline of his influence at court, and anticipating his dismissal from the command of the army at no distant period, he solicited from the Queen a patent constituting him Captain-general for life. In vain he was assured by the Lord Chancellor that such an appointment was wholly unprecedented in English history; he persisted in laying the petition before the Queen, by whom it was of course refused. Piqued at this disappointment, he wrote an acrimonious letter to her Majesty, in which he reproached her with the neglect of his public services, and bitterly complained of the neglect of the Duchess, and transfer of the royal favour to Mrs Masham. So deeply did Marlborough feel this disappointment, that on leaving the Hague to return to England, he said publicly to the deputies of the States—"I am grieved that I am obliged to return to England, where my services to your republic will be turned to my disgrace."[47]

Marlborough was received in the most flattering manner by the people, on landing on 15th November, and he was greeted by the thanks of both Houses of Parliament for his great and glorious services. The Queen declared in her speech from the throne, that this campaign had been at least as glorious as any which had preceded it; and the Chancellor, in communicating the thanks of the House of Lords, added—"This high eulogium must be looked upon as added to, and standing upon the foundation already laid in the records of this House, for preserving your memory fresh to all future times; so that your Grace has also the satisfaction of seeing this everlasting monument of your glory rise every year much higher." Such was the impulse communicated to both Houses by the presence of the Duke, and the recollection of his glorious services, that liberal supplies for carrying on the war were granted by both Houses. The Commons voted £6,000,000 for the service of the ensuing year, and on the earnest representation of Marlborough, an addition was made to the military forces.
