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 horsemen 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 that he had left, in a line extended toward Blenheim, and sent orders to the infantry in that village to leave it 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 array 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 krge body of French who garrisoned Blenheim were left exposed to certain destruction. Marlborough speedily occupied all the outlets from the village with his victorious troops, and then, collecting his artillery round it, he commenced a cannonade that speedily would have destroyed Blenheim itself and all who were in it. After several gallant but unsuccessful attempts to cut their way through the allies, the French in Blenheim were at length compelled to surrender at discretion; and twenty-four battalions and twelve squadrons, with all their officers, laid down their arms and became the captives of Marlborough.
