These lines, which had been making during the past three years, were now complete. They started from the Meuse a little to the east of Namur, passed from thence to the Mehaigne and the Little Geete, followed the Little Geete along its left bank to Leuw, the Great Geete from Leuw to the Demer, and the Demer itself as far as Arschot, from which point a new line of entrenchments carried the barrier through Lierre to Antwerp. Near Antwerp Marlborough had already had to do with these lines in 1703, but hitherto he had made no attempt to force them. Villeroy and the Elector of Bavaria now lay before him with seventy thousand men, a force superior to his own, but necessarily spread over a wide front for the protection of the entrenchments. The marshal’s headquarters were at Meerdorp, in the space between the Geete and the Mehaigne, which he probably regarded as a weak point. Marlborough posted himself over against him at Lens-les-Beguines, detaching a small force to recapture Huy, while Overkirk with the Dutch army covered the siege from Vignamont. Thus, as if daring the French to take advantage of the dispersion of his troops, he quietly laid his plans for forcing the lines. The point that he selected was on the Little Geete between Elixheim and Neerhespen, exactly in rear of the battlefield of Landen. The abrupt and slippery banks of the river, which the English knew but too well, together with the entrenchments beyond it, presented extraordinary difficulties; but the lines were on that account the less likely to be well guarded at that particular point. Marlborough had already obtained the leave of the States-General for the project, but he had now the far more difficult task of gaining the consent of the Dutch generals at a Council of War. Slangenberg and others opposed the scheme vehemently, but were overruled; and the Duke was at length at liberty to fall to work. ◆June 30./July 11.◆ Huy fell on the 11th of July, but to the general surprise the besieging force was not recalled. Six days later Overkirk and the covering army crossed the Mehaigne from Vignamont, and pushed forward detachments to the very edge of the lines between Meffle and Namur. ◆July.◆ Villeroy fell into the trap, withdrew troops from all parts of the lines and concentrated forty thousand men at Meerdorp. Marlborough then recalled the troops from Huy, and made them up to a total of about eight thousand men, both cavalry and infantry,[24] the whole being under the command of the Count of Noyelles. The utmost secrecy was observed in every particular. The corps composing the detachment knew nothing of each other, and nothing of the work before them; and, lest the sight of fascines should suggest an attack on entrenchments, these were dispensed with, the troopers only at the last moment receiving orders to carry each a truss of forage on the saddle before them. ◆July 6/17.◆
