With the arrival of Prince Eugene the campaign entered upon a new phase. Dissimilar as they were in character and temperament, the prince and the duke at once became fast friends. Eugene not merely fell under the spell of Marlborough’s personal force of character; he recognized his transcendent genius, and threw himself with enthusiasm into his plans. Unluckily, the Prince of Baden was a man of a different stamp. He was a soldier of the old school, brave as a lion, but wanting in judgment, cautious, methodical, a stickler for form. He joined the others in counsel at Gros Heppach, and being the eldest in rank expected that they would yield him the chief command. But the execution of their plan, so daringly conceived, demanded qualities he did not possess, and Marlborough had to exercise all the tact and patience of which he was so consummate a master. With much difficulty he persuaded the prince to share the command with him on alternate days, but not all his diplomacy availed to induce him to depart for the Rhine army. He insisted on remaining with Marlborough on the Danube, and Eugene had reluctantly to accept the other charge. On the 14th of June, therefore, Eugene left for Philipsburg, to watch Marshal Tallard, who was marching along the Rhine to join forces with the Elector of Bavaria. Harry accompanied him. Then began a fortnight of wearisome marching, in cold and rainy weather. The Elector of Bavaria was by this time aware that Marlborough’s design was to attack him, and in order to cover his dominions and check the confederate army until the expected reinforcements reached him he sent General D’Arco to occupy the Schellenberg, a height commanding Donauworth, on the north bank of the Danube. Hearing from Eugene that Tallard and Villeroy were at Strasburg organizing these reinforcements, Marlborough decided immediately to attack the Schellenberg. It happened to be his turn of command; he knew that if the day was allowed to pass Baden would find reasons for postponing the attempt, and after a hard march he threw his weary troops upon the position and carried it with heavy loss against an obstinate defence. A diplomatic attempt to detach the Elector from his alliance with France having failed, Bavaria, now open to the confederates, was put to fire and sword. Marlborough, one of the humanest generals that ever lived, refused to allow his own forces to engage in the work of burning and pillage, and did his utmost to restrain the excesses of the German soldiery. Eugene meanwhile, having failed to prevent the junction of Tallard with Marsin and the Elector of Bavaria, paid a hurried visit to Marlborough at his camp at Sandizell to concert operations against the now formidable enemy. Luckily, Prince Louis of Baden agreed to lay siege to Ingolstadt, and his colleagues were relieved of the presence of one whose captious temper was a continual stumbling-block.
