The deciding campaigns were in Belgium, where there were many fortresses, and progress was necessarily slow. After Marlborough's victory at Ramillies in 1706 the French lost ground, and when the princes, as they were called, took the field together, no French marshal had a chance. For Marlborough was now a prince of the empire; and Eugene, having driven the enemy out of Germany and Italy, was again by his side, thirsting for something to do. At Oudenarde, where he was present, with no troops of his own, at a critical moment he led a successful charge. Together they conquered Lille; and together they defeated Villars at Malplaquet. There, in the summer of 1709, the five years of constant victory which began at Blenheim came to an end. After Turin and Ramillies Lewis had been willing to treat. He was profoundly discouraged; and when Torcy came to The Hague in 1709 to meet the Triumvirate, Heinsius, Eugene, and Marlborough, he gave up almost every point. He even agreed that France should furnish men and money to drive Philip V out of Spain, where he felt quite safe and refused every summons. Lewis, in return, asked for Naples, and Naples only, without Sicily. The allies could have everything else, and could have compelled him to restore all the ill-gotten acquisitions of his reign. They were unwilling to be at the trouble of one more campaign in the Peninsula, where they had met with so much misfortune. They required that Lewis should undo his own offending deed, and himself compel his grandson to resign the Spanish throne. Marlborough, holding a position such as no Englishman had ever enjoyed, was preponderant in their councils. He aspired to be captain-general for life, and rejected an enormous sum with which France offered to repay his advocacy of peace. The attempt to prolong war for his own private advantage is the deadliest of his crimes. Lewis, in despair, made an appeal to his people, and a thrill of genuine indignation ran through the unhappy country. The tide began to turn. At Malplaquet, the greatest battle fought in modern Europe before Napoleon, the allies lost 23,000 out of less than 100,000; and the French not half so many.
