Crossing the river Neckar, Marlborough marched in a southeastern direction to Mundelshene, where he had his first personal interview with Prince Eugene, who was destined to be his colleague on so many glorious fields. Thence, through a difficult and dangerous country, Marlborough continued his march against the Bavarians, whom he encountered on July 2d on the heights of the Schullenberg, near Donauwoerth. Marlborough stormed their intrenched camp, crossed the Danube, took several strong places in Bavaria, and made himself completely master of the Elector's dominions except the fortified cities of Munich and Augsburg. But the Elector's army, though defeated at Donauwoerth, was still numerous and strong; and at last Marshal Tallard, when thoroughly apprised of the real nature of Marlborough's movements, crossed the Rhine; and being suffered, through the supineness of the German general at Stollhoffen, to march without loss through the Black Forest, he united his powerful army at Biberach, near Augsburg, with that of the Elector and the French troops under Marshal Marsin, who had previously been cooperating with the Bavarians. On the other hand, Marlborough recrossed the Danube, and on August 11th united his army with the Imperialist forces under Prince Eugene. The combined armies occupied a position near Hoechstaedt,[1] a little higher up the left bank of the Danube than Donauwoerth, the scene of Marlborough's recent victory, and almost exactly on the ground where Marshal Villars and the Elector had defeated an Austrian army in the preceding year. The French marshals and the Elector were now in position a little further to the east, between Blenheim and Luetzingen, and with the little stream of the Nebel between them and the troops of Marlborough and Eugene. The Gallo-Bavarian army consisted of about sixty thousand men, and they had sixty-one pieces of artillery. The army of the allies was about fifty-six thousand strong, with fifty-two guns.
