Marlborough commenced his celebrated march on the 19th of May. The army, which he was to lead, had been assembled by his brother, General Churchill, at Bedburg, not far from Maestricht on the Meuse: it included sixteen thousand English troops, and consisted of fifty-one battalions of foot, and ninety-two squadrons of horse. Marlborough was to collect and join with him on his march the troops of Prussia, Luneburg, and Hesse, quartered on the Rhine, and eleven Dutch battalions that were stationed at Rothweil. [Coxe's Life of Marlborough.] He had only marched a single day, when the series of interruptions, complaints, and requisitions from the other leaders of the Allies began, to which he seemed doomed throughout his enterprise, and which would have caused its failure in the hands of any one not gifted with the firmness and the exquisite temper of Marlborough. One specimen of these annoyances and of Marlborough's mode of dealing with them may suffice. On his encamping at Kupen, on the 20th, he received an express from Auverquerque pressing him to halt, because Villeroy, who commanded the French army in Flanders, had quitted the lines, which he had been occupying, and crossed the Meuse at Namur with thirty-six battalions and forty-five squadrons, and was threatening the town of Huys. At the same time Marlborough received letters from the Margrave of Baden and Count Wratislaw, who commanded the Imperialist forces at Stollhoffen near the left bank of the Rhine, stating that Tallard had made a movement, as if intending to cross the Rhine, and urging him to hasten his march towards the lines of Stollhoffen. Marlborough was not diverted by these applications from the prosecution of his grand design. Conscious that the army of Villeroy would be too much reduced to undertake offensive operations, by the detachments which had already been made towards the Rhine, and those which must follow his own march, he halted only a day to quiet the alarms of Auverquerque. To satisfy also the margrave he ordered the troops of Hompesch and Bulow to draw towards Philipsburg, though with private injunctions not to proceed beyond a certain distance. He even exacted a promise to the same effect from Count Wratislaw, who at this juncture arrived at the camp to attend him during the whole campaign. [Coxe.]
