Marlborough’s eye, however, was everywhere; and galloping to the spot, he put himself at the head of some squadrons of British cavalry, and, closely followed by three battalions of fresh infantry, charged the Irish battalions, who, in the impetuosity of their pursuit, had fallen into disorder.  The cavalry charge completed their confusion, and the infantry opening fire in flank on the lately victorious column, drove it back with immense slaughter.  Thus the battle was restored at this point.

All this time the fight had raged between Eugene’s array and the Bavarians and French opposed to them.  At first the prince had been successful, and the Danes and Prussians under his orders captured a battery of six guns.  His cavalry, however, while advancing in some disorder, were charged by the French, driven back across the Nebel, and the guns were retaken.  Twice the prince himself rallied his cavalry, and brought them back to the charge, but each time the Bavarian horse, led by the elector, drove them back, defeated and broken, across the river.  The Prussian and Danish infantry stood their ground nobly, although the enemy charged them over and over again; but, cheered by the presence of Prince Eugene, who took his place amongst them, they beat off all attacks.

The Duke of Marlborough, after restoring the battle at Oberglau, rode back to his centre, and prepared for the grand attack by his cavalry.  Marshal Tallard, in preparation for the attack he saw impending, brought up six battalions of infantry, and placed them in the centre of the ridge.  Marlborough brought up three battalions of Hessians to front them, placed the rest of his infantry to cover the left of the cavalry from the attack of the strong battalions in Blenheim, and then, drawing his sword, placed himself in front of his troops, and ordered the trumpets to sound the advance.

This grand and decisive charge is thus described by Allison in his “Life of Marlborough:” 

“Indescribably grand was the spectacle that ensued.  In compact order, and in the finest array, the allied cavalry, mustering 8000 sabres, moved up the gentle slope in two lines—­at first slowly, as on a field day, but gradually more quickly as they drew near, and the fire of the artillery became more violent.  The French horse, 10,000 strong, stood their ground at first firmly.  The choicest and bravest of their chivalry were there; the banderolls of almost all the nobles of France floated over the squadrons.

“So hot was the fire of musketry and cannon when the assailants drew near, that their advance was checked.  They retired sixty paces, and the battle was kept up for a few minutes only by a fire of artillery.  Gradually, however, the fire of the artillery slackened; and Marlborough, taking advantage of the pause, led his cavalry again to the charge.  With irresistible vehemence the line dashed forward at full speed, and soon the crest of the ridge was passed.  The French horsemen discharged their carbines at a considerable distance with little effect, and immediately wheeled about and fled.
