The French horsemen discharged their carbines at a considerable distance with little effect, and immediately wheeled about and fled.
"The battle was gained.

The allied horse rapidly inundated the open space between the two villages.

The six battalions in the middle were surrounded, cut to pieces, or taken.

They made a noble resistance; and the men were found lying on their backs in their ranks as they had stood in the field." Thus at one blow the whole French line of defence was broken up.
Blenheim was entirely cut off; and the rear of their left beyond Oberglau threatened.
General Marsin's cavalry, seeing the defeat of their main body, fell back to avoid being taken in rear; and Prince Eugene, seeing the Bavarian infantry left unsupported, called up all his reserves, and advanced at the head of the Danes and Prussians against them.
The Bavarian infantry fought stubbornly, but the battle was lost, their line of retreat threatened by the allied horse, who were now masters of the field, and, setting fire to the villages of Oberglau and Lutzingen, they fell back sullenly.
In the meantime, Marshal Tallard was striving bravely to avert the defeat.

He brought up his last reserves, rallied his cavalry, and drew them up in line stretching towards Blenheim in hopes of drawing off his infantry from that village.
