William, to do him justice, had strained every nerve to spur his indolent allies to be first in the field. The contingents, awaked by the sudden stroke at Namur, came in fast to Brussels; but it was too late. The French had destroyed all forage and supplies on the direct route to Namur, and William's only way to the city lay across the Mehaigne. Behind the Mehaigne lay Luxemburg, the ablest of the French generals. The best of luck was essential to William's success, and instead of the best came the worst. Heavy rain swelled the narrow stream into a broad flood, and the building of bridges became impossible. There was beautiful fencing, skilful feint, and more skilful parry, between the two generals, but William could not get under Luxemburg's guard. On the 5th of June, after a discreditably short defence, Namur fell, almost before William's eyes, into the hands of the French. [Sidenote: July 23 ------- August 2. ] Then Luxemburg thought it time to draw the enemy away from the vicinity of the captured city; so recrossing the Sambre, and keeping Boufflers always between himself and that river, he marched for the Senne as if to threaten Brussels. William followed, as in duty bound; and French and Allies pursued a parallel course to the Senne, William on the north and Luxemburg on the south. The 2nd of August found both armies across the Senne, William at Hal, facing west with the river in his rear, and Luxemburg some five miles south of him with his right at Steenkirk, and his centre between Hoves and Enghien, while Boufflers lay at Manny St. Jean, seven miles in his rear. The terrible state of the roads owing to heavy rain had induced Luxemburg to leave most of his artillery at Mons, and as he had designed merely to tempt the Allies away from Namur, the principal object left to him was to take up a strong position wherein his worn and harassed army could watch the enemy without fear of attack. Such a position he thought that he had found at Steenkirk.[263] The country at this point is more broken and rugged than is usual in Belgium. The camp lay on high ground, with its right resting on the river Sennette and its right front covered by a ravine, which gradually fades away northward into a high plateau of about a mile in extent. Beyond the ravine was a network of wooded defiles, through which Luxemburg seems to have hoped that no enemy could fall upon him in force unawares. It so happened, however, that one of his most useful spies was detected, in his true character, in William's camp at Hal; and this was an opportunity not to be lost. A pistol was held at the spy's head, and he was ordered to write a letter to Luxemburg, announcing that large bodies of the enemy would be in motion next morning, but that nothing more serious was contemplated than a foraging expedition. This done, William laid his plans to surprise his enemy on the morrow. [Sidenote: July 23 -------- August 3. ]
