Villars now set himself with immense energy to strengthen his position; and, when Marlborough and Eugene surveyed the defences at daybreak of the following morning, they were astonished at the formidable appearance of the entrenchments. Marlborough was once more for attacking without further delay, but he was opposed by the Dutch deputies and even by Eugene. The attack was therefore fixed for the morrow; and another day was lost which Villars did not fail to turn to excellent account.

The entrance from the westward to the Trouée d'Aulnois or southern entrance to the plain of Mons is marked by the two villages of Campe du Hamlet on the north and Malplaquet on the south. About a mile in advance of these villages the ground rises to its highest elevation, the opening being about three thousand paces wide, and the ground broken and hollowed to right and left by small rivulets. This was the point selected by Villars for his position. It was bounded on his right by the forest of Laignières, the greatest length of which ran parallel to the Trouée, and on the left by a forest, known at different points by the names of Taisnières, Sart and Blaugies, the greatest length of which ran at right angles to the Trouée. Villars occupied the forest of Laignières with his extreme right, his battalions strengthening the natural obstacles of a thick and tangled covert by means of abattis. From the edge of the wood he constructed a triple line of entrenchments, which ran across the opening for full a third of its width, when they gave way to a line of nine redans. These redans in turn yielded place to a swamp backed by more entrenchments, which carried the defences across to the wood of Taisnières. Several cannon were mounted on the entrenchments and a battery of twenty guns before the redans. On Villars's left the forests of Taisnières and Sart projected before the general front, forming a salient and re-entering angle. Entrenchments and abattis were constructed in accordance with this configuration, and two more batteries were erected on this side, in addition to several guns at various points along the line, to enfilade an advancing enemy. Feeling even thus insecure Villars threw up more entrenchments at the villages of Malplaquet and Chaussée du Bois in rear of the wood of Sart, and was still hard at work on them to the last possible moment before the action. Finally in rear of all stood his cavalry, drawn up in several lines. The whole of his force amounted to ninety-five thousand men.

The position was most formidable, but it had its defects. In the first place the open space before the entrenchments was broken at about half a mile's distance by a small coppice, called the wood of Tiry, which could serve to mask the movements of the Allied centre. In the second place the forest of Sart ran out beyond the fortified angle in a long tongue, which would effectually conceal any troops that might be directed against the extreme left flank. Finally the French cavalry, being massed in rear of the entrenchments, could take no part in the action until the defences were forced, and was therefore incapable of delivering any counterstroke. Marlborough and Eugene accordingly decided to make a feint attack on the French right and a true attack on their left front and flank. Villars would then be obliged to reinforce his left from his centre, which would enable the defences across the open to be carried, and the whole of the allied cavalry to charge forward and cut the French line in twain.

Aug. 31
Sept. 11.

The dawn of the 11th of September broke in dense heavy mist which completely veiled the combatants from each other. At three o'clock prayers were said in the Allied camp, and then the artillery was moved in position. Forty pieces were massed in a single battery in the open ground against the French left, and were covered with an epaulment for defence against enfilading fire; twenty-eight more were stationed against the French right, and the lighter pieces were distributed, as usual, among the different brigades. Then the columns of attack were formed. Twenty-eight battalions under Count Lottum were directed against the eastern face of the salient angle of the forest of Taisnières, and forty battalions of Eugene's army under General Schulemberg against the northern face, while a little to the right of Schulemberg two thousand men under General Gauvain were to press on the French left flank in rear of their entrenchments. In rear of Schulemberg fifteen British battalions under Lord Orkney were drawn up in a single line on the open ground, ready to advance against the centre as soon as Schulemberg and Lottum should have done their work. Far away beyond Gauvain to the French left General Withers with five British and fourteen foreign battalions and six squadrons was to turn the extreme French left at the village of La Folie.

For the feint against the French right thirty-one battalions, chiefly Dutch, were massed together under the Prince of Orange. The cavalry was detailed in different divisions to support the infantry. The Prince of Orange was backed by twenty-one Dutch squadrons under the Prince of Hesse, Orkney by thirty more under Auvergne, Lottum by the British and Hanoverian cavalry, and Schulemberg by Eugene's horse. The orders given to the cavalry were to sustain the foot as closely as possible without advancing into range of grape-shot, and as soon as the central entrenchments were forced to press forward, form before the entrenchments and drive the French army from the field. The whole force of the Allies was as near as may be equal to that of the French.

At half-past seven the fog lifted and the guns of both armies opened fire. Eugene and Marlborough thereupon parted, the former taking charge of the right, the latter of the left of the army. Then the divisions of Orange and of Lottum advanced in two dense columns up the glade. Presently the Dutch halted, just beyond range of grape-shot, while Lottum's column pushed on under a terrific fire to the rear of the forty-gun battery and deployed to the right in three lines. Then the fire of the cannon slackened for a time, till about nine o'clock a salvo of the forty guns gave the signal for attack. Lottum's and Schulemberg's divisions thereupon advanced perpendicularly to each other, each in three lines, Gauvain's men crept into the wood unperceived, and Orkney extended his scarlet battalions across the glade.

Entering the wood Schulemberg's Austrians made the best of their way through marshes and streams and fallen trees, nearer and nearer to the French entrenchments. The enemy suffered them to approach within pistol-shot and delivered a volley which sent them staggering back; and though the Austrians extended their line till it joined Gauvain's detachment, yet they could make little way against the French fire. Lottum's attack was little more successful. Heedless of the tempest of shot in their front and flank the Germans pressed steadily on, passed a swamp and a stream under a galling fire, and fell fiercely upon the breastwork beyond; but being disordered by the ground and thinned by heavy losses they were forced to fall back. Schulemberg then resumed the attack with his second line, but with all his exertions could not carry the face of the angle opposed to him. Picardie, the senior regiment of the French Line, held this post and would not yield it to the fiercest assault. The utmost that Schulemberg could accomplish was to sweep away the regiments in the wood, and so uncover its flank.

Lottum, too, extended his front and attacked once more, Orkney detaching three British battalions, the Buffs, Sixteenth, and Temple's, to his assistance, while Marlborough took personal command of Auvergne's cavalry in support. The Buffs on Lottum's extreme left found a swamp between them and the entrenchments, so deep as to be almost impassable. In they plunged, notwithstanding, and were struggling through it when a French officer drew out twelve battalions and moved them down straight upon their left flank. The British brigade would have been in a sorry plight had not Villars caught sight of Marlborough at the head of Auvergne's horse and instantly recalled his troops. So the red-coats scrambled on, and turning the flank of the entrenchment while Lottum's men attacked the front, at length with desperate fighting and heavy loss forced the French back into the wood. Thus exposed to the double attack of Lottum and Schulemberg Picardie at last fell back, but joined itself to Champagne, the next regiment in seniority; and the two gallant corps finding a rallying-point behind an abattis turned and stood once more. Their comrades gave way in disorder, but the wood was so dense that the troops on both sides became disjointed, and the opposing lines broke up into a succession of small parties fighting desperately from tree to tree with no further guidance than their own fury.
