It was the Italian blood which formed that character most, but he was thoroughly French by birth and training. Born in Paris, and desiring a career in the French army, it was a slight offered to his mother by the French king that gave his whole life a personal hatred of Louis XIV. for its motive. From boyhood till his death, between sixty and seventy, this great captain directed his energies uniquely against the fortunes of the French king. When, later in life, there was an attempt to acquire his talents for the French service, he replied that he hoped to re-enter France, but only as an invader. It has been complained that he lacked precision in detail, and that as an organiser he was somewhat at fault; but he had no equal for rapidity of vision, and for seizing the essential point in a strategic problem. From that day in his twentieth year when he had assisted at Sobiesky's destruction of the Turks before Vienna, through his own great victory which crushed that same enemy somewhat later at Zenta, in all his career this quality of immediate perception had been supremely apparent. He was at this moment--the end of the campaign of 1703--the head of the imperial council of war; and he it was who first grasped the strategic necessity which 1703 had created. The determination to carry the defence of the empire into the valley of the Upper Danube was wholly his own. He wrote to Marlborough suggesting a withdrawal of forces as considerable as possible from the northern field to the southern. By a happy accident, the judgment of the Englishman exactly coincided with his own, and indeed there was so precise a sympathy between these two very different men that when they met in the course of the ensuing campaign there sprang up between them not only a lasting friendship, but a mutual comprehension which made the combination of their talents invincible during those half dozen years of the war which all but destroyed the French power. * * * * * Such was the origin of Marlborough's advance southward from the Netherlands in the early summer of 1704, an advance famous in history under the title of "the march to the Danube." PART III THE MARCH TO THE DANUBE The position of the enemy at the moment when Marlborough's march to the Danube from the Netherlands was conceived may be observed in the sketch map on page 59. Under Villeroy, who must be regarded as the chief of the French commanders of the moment, lay the principal army of Louis XIV., with the duty of defending the northern front and of watching the Lower Rhine. It was this main force which was expected to have to meet the attack of Marlborough and the Dutch in the same field of operations as had seen the troops in English pay at work during the two preceding years. But Villeroy was, of course, free to detach troops southwards somewhat towards the Middle Rhine, or the valley of the Moselle, if, as later seemed likely, an attack should be made in that direction.
