Though Villars was relieved by the departure of Eugene from a considerable part of the force opposed to him, and he naturally felt desirous of now measuring his strength with his great antagonist in a decisive affair, yet he was restrained from hazarding a general engagement. Louis, trusting to the progress of the Tory intrigues in England, and daily expecting to see Marlborough and the war-party overthrown, sent him positive orders not to fight; and soon after detached twenty-five battalions and forty squadrons, in two divisions, to the Upper Rhine, to watch the movements of Eugene. Villars encouraged this separation, representing that the strength of his position was such, that he could afford to send a third detachment to the Upper Rhine, if it was thought proper. Marlborough, therefore, in vain offered battle, and drew up his army in the plain of Lens for that purpose. Villars cautiously remained on the defensive; and, though he threw eighteen bridges over the Scarpe, and made a show of intending to fight, he cautiously abstained from any steps which might bring on a general battle.32 It was not without good reason that Louis thus enjoined his lieutenant to avoid compromising his army. The progress of the negotiations with England gave him the fairest ground for believing that he would obtain nearly all he desired from the favour with which he was regarded by the British cabinet without running any risk. He had commenced a separate negotiation with the court of St James's, which had been favourably received; and Mr Secretary St John had already transmitted to Lord Raby, the new plenipotentiary at the Hague, a sketch of six preliminary articles proposed by the French king, which were to be the basis of a general peace.33
The high tone of these proposals proved how largely Louis counted upon the altered dispositions of the British cabinet. The Spanish succession, the real object of the war, was evaded. Every thing was directed to British objects, and influenced by the desire to tempt the commercial cupidity of England to the abandonment of the great objects of her national policy. Real security was tendered to the British commerce with Spain, the Indus, and the Mediterranean; the barrier the Dutch had so long contended for was agreed to; a reasonable satisfaction was tendered to the allies of England and Holland; and, as to the Spanish succession, it was to be left to "new expedients, to the satisfaction of all parties interested." These proposals were favourably received by the British ministry; they were in secret communicated to the Pensionary Heinsius, but concealed from the Austrian and Piedmontese plenipotentiaries; and they were not communicated to Marlborough– a decisive proof both of the altered feeling of the cabinet towards that general, and of the consciousness on their part of the tortuous path on which they were now entering.34
After much deliberation, and a due consideration of what could be effected by the diminished force now at his disposal, which, by the successive drafts to Eugene's army, was now reduced to one hundred and nineteen battalions, and two hundred and fifty-six squadrons, not mustering above seventy-five thousand combatants, Marlborough determined to break through the enemies' boasted lines; and, after doing so, undertake the siege of Bouchain, the possession of which would give him a solid footing within the French frontier. With this view, he had long and minutely studied the lines of Villars; and he hoped that, even with the force at his disposal, they might be broken through. To accomplish this, however, required an extraordinary combination of stratagem and force; and the manner in which Marlborough contrived to unite them, and bring the ardent mind and lively imagination of his adversary to play into his hands, to the defeat of all the objects he had most at heart, is perhaps the most wonderful part of his whole military achievements.35
During his encampment at Lewarde, opposite Villars, the English general had observed that a triangular piece of ground in front of the French position, between Cambray, Aubanchocil-au-bac, and the junction of the Sauzet and Scheldt, offered a position so strong, that a small body of men might defend it against a very considerable force. He resolved to make the occupation of this inconsiderable piece of ground the pivot on which the whole passage of the lines should be effected. A redoubt at Aubigny, which commanded the approach to it, was first carried without difficulty. Arleux, which also was fortified, was next attacked by seven hundred men, who issued from Douay in the night. That post also was taken, with one hundred and twenty prisoners. Marlborough instantly used all imaginable expedition in strengthening it; and Villars, jealous of a fortified post so close to his lines remaining in the hands of the Allies, attacked it in the night of the 9th July; and, though he failed in retaking the work, he surprised the Allies at that point, and made two hundred men and four hundred horses prisoners. Though much chagrined at the success of this nocturnal attack, the English general now saw his designs advancing to maturity. He therefore left Arleux to its own resources, and marched towards Bethune. That fort was immediately attacked by Marshal Montesquieu, and, after a stout resistance, carried by the French, who made the garrison, five hundred strong, prisoners. Villars immediately razed Arleux to the ground, and withdrew his troops; while Marlborough, who was in hopes the lure of these successes would induce Villars to hazard a general engagement, shut himself up in his tent, and appeared to be overwhelmed with mortification at the checks he had received.36
Villars was so much elated with these successes, and the accounts he received of Marlborough's mortification, that he wrote to the king of France a vain-glorious letter, in which he boasted that he had at length brought his antagonist to a ne plus ultra. Meanwhile, Marlborough sent off his heavy baggage to Douay; sent his artillery under a proper guard to the rear; and, with all imaginable secresy, baked bread for the whole troops for six days, which was privately brought up. Thus disencumbered and prepared, he broke up at four in the morning on the 1st of August, and marched in eight columns towards the front. During the three following days, the troops continued concentrated, and menacing sometimes one part of the French lines and sometimes another, so as to leave the real point of attack in a state of uncertainty. Seriously alarmed, Villars concentrated his whole force opposite the Allies, and drew in all his detachments, evacuating even Aubigny and Arleux, the object of so much eager contention some days before. On the evening of the 4th, Marlborough, affecting great chagrin at the check he had received, spoke openly to those around him of his intention of avenging them by a general action, and pointed to the direction the attacking columns were to take. He then returned to the camp, and gave orders to prepare for battle. Gloom hung on every countenance of those around him; it appeared nothing short of an act of madness to attack an enemy superior in number, and strongly posted in a camp surrounded with entrenchments, and bristling with cannon. They ascribed it to desperation, produced by the mortifications received from the government, and feared that, by one rash act, he would lose the fruit of all his victories. Proportionally great was the joy in the French camp, when the men, never doubting they were on the eve of a glorious victory, spent the night in the exultation which, in that excitable people, has so often been the prelude to disaster.37
Having brought the feeling of both armies to this point, and produced a concentration of Villars's army directly in his front, Marlborough, at dusk on the 4th, ordered the drums to beat; and before the roll had ceased, orders were given for the tents to be struck. Meanwhile Cadogan secretly left the camp, and met twenty-three battalions and seventeen squadrons, drawn from the garrisons of Lille and Tournay, which instantly marched; and continuing to advance all night, passed the lines rapidly to the left, without opposition at Arleux, at break of day. A little before nine, the Allied main army began to defile rapidly to the left, through the woods of Villers and Neuville – Marlborough himself leading the van, at the head of fifty squadrons. With such expedition did they march, still holding steadily on to the left, that before five in the morning of the 5th they reached Vitry on the Scarpe, where they found pontoons ready for their passage, and a considerable train of field artillery. At the same time, the English general here received the welcome intelligence of Cadogan's success. He instantly dispatched orders to every man and horse to press forward without delay. Such was the ardour of the troops, who all saw the brilliant manœuvre by which they had outwitted the enemy, and rendered all their labour abortive,
