Like Hannibal, Marlborough relied principally on his cavalry for achieving his decisive successes, and it was by his cavalry that Blenheim, the greatest of his victories, was won. The battle had lasted till five in the afternoon. Marlborough had now eight thousand horseman drawn up in two lines, and in the most perfect order for a general attack on the enemy's line along the space between Blenheim and Oberglau. The infantry was drawn up in battalions in their rear, so as to support them if repulsed, and to keep in check the large masses of the French that still occupied the village of Blenheim. Tallard now interlaced his squadrons of cavalry with battalions of infantry; and Marlborough by a corresponding movement, brought several regiments of infantry, and some pieces of artillery, to his front line, at intervals between the bodies of horse. A little after five, Marlborough commenced the decisive movement, and the allied cavalry, strengthened and supported by foot and guns, advanced slowly from the lower ground near the Nebel up the slope to where the French cavalry, ten thousand strong, awaited them. On riding over the summit of the acclivity, the Allies were received with so hot a fire from the French artillery and small arms, that at first the cavalry recoiled, but without abandoning the high ground. The guns and the infantry which they had brought with them, maintained the contest with spirit and effect. The French fire seemed to slacken Marlborough instantly ordered a charge along the line. The allied cavalry galloped forward at the enemy's squadrons, and the hearts of the French horseman failed them. Discharging their carbines at an idle distance, they wheeled round and spurred from the field, leaving the nine infantry battalions of their comrades to be ridden down by the torrent of the allied cavalry. The battle was now won. Tallard and Marsin, severed from each other, thought only of retreat. Tallard drew up the squadrons of horse which he had left in a line extended towards Blenheim, and sent orders to the infantry in that village to leave and join him without delay. But long ere his orders could be obeyed, the conquering squadrons of Marlborough had wheeled to the left and thundered down on the feeble army of the French marshal. Part of the force which Tallard had drawn up for this last effort was driven into the Danube; part fled with their general to the village of Sonderheim, where they were soon surrounded by the victorious Allies, and compelled to surrender. Meanwhile, Eugene had renewed his attack upon the Gallo-Bavarian left, and Marsin, finding his colleague utterly routed, and his own right flank uncovered, prepared to retreat. He and the Elector succeeded in withdrawing a considerable part of their troops in tolerable order to Dillingen; but the large body of French who garrisoned Blenheim were left exposed to certain destruction. Marlborough speedily occupied all the outlets from the village with
