Marlborough had watched, with the deepest anxiety, the progress of the French arms on the Rhine and in Bavaria, and he saw the futility of carrying on a war of posts and sieges in Flanders, while death-blows to the empire were being dealt on the Danube. He resolved therefore to let the war in Flanders languish for a year, while he moved with all the disposable forces that he could collect to the central scenes of decisive operations. Such a march was in itself difficult, but Marlborough had, in the first instance, to overcome the still greater difficulty of obtaining the consent and cheerful co-operation of the Allies, especially of the Dutch, whose frontier it was proposed thus to deprive of the larger part of the force which had hitherto been its protection. Fortunately, among the many slothful, the many foolish, the many timid, and the not few treacherous rulers, statesmen, and generals of different nations with whom he had to deal, there were two men, eminent both in ability and integrity, who entered fully into Marlborough's projects, and who, from the stations which they occupied, were enabled materially to forward them. One of these was the Dutch statesman Heinsius, who had been the cordial supporter of King William, and who now, with equal zeal and good faith, supported Marlborough in the councils of the Allies; the other was the celebrated general Prince Eugene, whom the Austrian cabinet had recalled from the Italian frontier, to take the command of one of the Emperor's armies in Germany. To these two great men, and a few more, Marlborough communicated his plan freely and unreservedly; but to the general councils of his allies he only disclosed part, of his daring scheme. He proposed to the Dutch that he should march from Flanders to the Upper Rhine and Moselle, with the British troops and part of the Foreign auxiliaries, and commence vigorous operations against the French armies in that quarter, whilst General Auverquerque, with the Dutch and the remainder of the auxiliaries, maintained a defensive war in the Netherlands. Having with difficulty obtained the consent of the Dutch to this portion of his project, he exercised the same diplomatic zeal, with the same success, in urging the King of Prussia, and other princes of the empire, to increase the number of the troops which they supplied, and to post them in places convenient for his own intended movements.
