The Prince of Hessen-Cassel soon overtook Orkney, from whom he learned that St. Ghislain was too strongly held to be carried by his small force. The Prince therefore at once pushed on. Rain was falling in torrents, and the roads were like rivers, but he continued his advance eastward behind the woods that line the Haine almost without a halt, till at length at two o'clock on the morning of the 6th of September he wheeled to the right and crossed the river at Obourg three miles to the north-east of Mons. Before him lay the river Trouille running down from the south through Mons, and in rear of it a line of entrenchments, thrown up from Mons to the Sambre during the last war to cover the province of Hainault. A short survey showed him that the lines were weakly guarded; and before noon he had passed them without opposition. His force, despite the weather and the state of the roads, had covered the fifty miles to Obourg in fifty-six hours.

Too late Villars discovered that for the second time he had been duped, and that Marlborough had no intention of forcing his way into France through the lines of La Bassée and the wet swampy country beyond them, when he could pass the lines of the Trouille without loss of a man. He was in a difficult position, for Mons was but slenderly garrisoned and difficult of access, while, if captured, it would be a valuable acquisition to the Allies. The approach to it from the westward was practically shut off by a kind of natural barrier of forest, running, roughly speaking, from St. Ghislain on the Haine on the north to Maubeuge on the Sambre to the south. In this barrier there were but two openings, the Trouée de Boussut between the village of that name and the Haine, and the Trouées d'Aulnois and de Louvière, which are practically the same, some miles further to the south. These will be more readily remembered, the northern entrance by the name of Jemappes, the southern by the name of Malplaquet. Villars no sooner knew what was going forward than he pushed forward a detachment with all speed upon the northern entrance, which was the nearer to him. The detachment came too late. The Prince of Hessen-Cassel was already astride of it, his right at Jemappes, his left at Ciply. The French thereupon fell back to await the approach of the main army of the Allies.

Meanwhile that army had toiled through the sea of mud on the northern bank of the Haine, and crossing the river had by evening invested Mons on the eastern side. On the following day Villars and his whole army also arrived on the scene and encamped a couple of miles to westward of the forest-barrier from Montreuil to Athis. Here he was joined by old Marshal Boufflers, who had volunteered his services at a time of such peril to France. The arrival of the gallant veteran caused such a tumult of rejoicing in the French camp that Marlborough and Eugene, not knowing what the clamour might portend, withdrew all but a fraction of the investing force from the town, and advancing westward into the plain of Mons caused the army to bivouac between Ciply and Quévy in order of battle.

Villars meanwhile had not moved, being adroit enough to threaten both passages and keep the Allies in doubt as to which he should select. While therefore the mass of the Allied army was moved towards the Trouée d'Aulnois, a strong detachment was sent up to watch the Trouée de Boussut. That night Villars sent detachments forward to occupy the southern passage, and by midday of the morrow his whole army was taking up its position across the opening. Marlborough at once moved his army forward, approaching so close that his left wing exchanged cannon shot with Villars's right. Everything pointed to an immediate attack on the French before they should have time to entrench themselves. Whether the Dutch deputies intervened to stay further movements is uncertain. All that is known is that a council of war was held, wherein, after much debate, it was resolved to await the arrival of the detachment from the Trouée de Boussut and of the troops that had been left behind at Tournay, and that in the meanwhile eighteen battalions should be sent north to the capture of St. Ghislain and the investment of Mons turned into a blockade. Evidently in some quarter there was reluctance to hazard a general action.
