Fresh squadrons of French cavalry came up, and General Lumley sent some squadrons of cavalry across to Rowe’s assistance.  Then, with a cheer, the dragoons rode at the French, who were twice their strength.  In an instant every one was engaged in a fierce conflict, cutting, slashing, and using their points.

The French gave way under the onslaught, but fresh squadrons came up from their side, a heavy musketry fire broke out from the enclosure round Blenheim, and leaving many of their number behind them, the British horse and foot fell back to the stream.

Marlborough, seeing that Blenheim could not be taken, now resolved upon making his great effort to break the French line midway between Oberglau and Blenheim.

On the stream at this part stood the village of Unterglau, having a stone bridge across the Nebel.  This was but weakly held by the French, who, upon seeing the allies advancing at full speed, fired the village to check the advance, and then fell back.

General Churchill’s division rushed through the burning village, crossed the bridge, and began to open out on both sides.  Then the duke gave the order for the whole cavalry to advance.  Headed by the English dragoons, they came down in good order through the concentrated fire of the enemy’s batteries to the edge of the stream; but the difficulties here were immense.  The stream was divided into several branches, with swampy meadows between them, and only by throwing down fascines could a footing be obtained for the horses.

“I don’t call this fighting, Master Rupert,” Hugh said, as they floundered and struggled through the deep marshes, while the enemy’s shell burst in and around the ranks; “it’s more like swimming.  Here come the French cavalry, and we’ve not even formed up.”

Had the French charge been pressed home, the dragoons must have been crushed; but Churchill’s infantry on their right opened such a heavy fire that the French cavalry at that end of the line paused.  On their left, however, near Blenheim, the dragoons, suffering terribly from the artillery and musketry fire from that village, were driven back by the French cavalry to the very edge of the swamp.

Marlborough, however, anxiously watching the struggle, continued to send fresh bodies of horse across to their assistance, until the Dutch and Hanoverian squadrons were all across, and the allied cavalry formed in two long lines.

While this had been going on, a serious fight had been raging in front of Oberglau; and here, as at Blenheim, the allies suffered disaster.  Here the Hanoverians, led by the Prince of Holstein, had attacked.  The powerful body of French and Irish infantry did not, however, wait for the assault, but, 9000 strong, charged down the slope upon the 5000 Hanoverians before they had formed up after crossing the river, repulsed them with great loss, and took the prince himself prisoner.

This was a serious disaster, as, by the rout of the Hanoverians the connexion between Marlborough’s army and that of Prince Eugene was broken.
