On 10 June, Marlborough met for the first time the President of the Imperial War Council, Prince Eugene – accompanied by Count Wratislaw – at the village of Mundelsheim, halfway between the Danube and the Rhine. By 13 June, the Imperial Field Commander, Prince Louis, had joined them in Großheppach. The three generals commanded a force of nearly 110,000 men. At this conference it was decided that Prince Eugene would return with 28,000 men to the Lines of Stollhofen on the Rhine to watch Villeroi and Tallard and prevent them going to the aid of the Franco-Bavarian army on the Danube. Meanwhile, Marlborough's and Prince Louis's forces would combine, totalling 80,000 men, and march on the Danube to seek out Maximilian II and Marsin before they could be reinforced.
