A portion of the French army was already in movement, when the news came that the allies were fast coming up. Early the next morning their advance guard, composed of twelve battalions of infantry and the whole of the cavalry, reached the Scheldt; and, having thrown bridges over the river, crossed, and soon came in contact with the French advance guard, under Biron. There was some severe fighting, in which neither party gained any great advantage, the French maintaining possession of the village of Eynes.
While this conflict was going on, Marlborough and Eugene, with the main body, had reached the river, and were engaged in crossing it; and Vendome determined to attack them while carrying out the operation. He was, as usual, opposed by Burgundy, who wished to continue the march to Ghent. Marshal Vendome pointed out that, in a country so broken and interspersed with hedges, an army possessing the greatest strength--for the French numbered eighty-five thousand, while Marlborough had but eighty thousand under him--would lose the advantage of that superiority; and, upon Berwick strongly siding with the marshal, Burgundy was forced to give way.
The discussion lasted some time, enabling the allies to pass bodies of troops across the river, where they were formed up at a village a few hundred yards north of Oudenarde; and immediately Marlborough felt strong enough to risk an attack, orders were sent to Cadogan, who commanded the advance guard, to drive the enemy out of Eynes.
Four English battalions attacked the seven French battalions in the village, while the cavalry crossed higher up, and came down on the back of the village. Three of the French battalions were surrounded and made prisoners, while the other four were dispersed.
It was now evident, even to Burgundy, that an action could not be avoided, but again an angry dispute took place. Vendome would have stood on the defensive, with the river Norken to be crossed before he could be attacked. He was, however, overruled by Burgundy, who had nominally chief command. Marlborough took advantage of the delay, and posted his troops in front of the castle of Bevere, and sent the twelve battalions at Eynes to reinforce his left, against which he saw the main attack of the French would be directed. He then lined all the hedges with infantry, and stationed twenty British battalions, under Argyle, in reserve.
Crossing the Norken, the French fell upon the Dutch and Hanoverians, who constituted the left wing, and who, though fighting obstinately, were driven back. Marlborough moved from the centre with twenty battalions to reinforce them, and despatched Eugene to command on the right.
A desperate fight now took place. On both flanks, the ground was broken by enclosures with deep wet ditches, bridges, woods, and small villages; and the cavalry were unable to act on such ground. The infantry on both sides fought with extreme resolution; every hedge, ditch, bridge, and house being defended to the last. Seldom, indeed, in modern warfare, has so obstinate and terrible a fight taken place. Frequently the combatants were mingled together, and fought with bayonets and the butt ends of their muskets.
Gradually, however, the Dutch and the Hanoverian battalions won their way forward, and drove the French back to the village of Diepenbeck, where the latter successfully maintained themselves. Marlborough then ordered General Overkirk to move round and seize the hill at Oycke, which, although it flanked the enemy's position, was not held by them.
This he did, with twenty Dutch and Danish battalions, who had only just crossed the river. He then pressed on and seized the mill of Royegham, thus cutting the communication between the French at Diepenbeck and the troops that still remained on the plateau beyond the Norken. Eugene then swung round his right, and, pressing forward, surrounded the French on that side, so completely enveloping them that his men and those of Overkirk each believed the other to be French--for darkness had now fallen--and fought for some time before the mistake was discovered.
As, in such a country, it was impossible to move troops in regular formation in the darkness, Marlborough gave orders for the troops to halt in the positions they held. Had the light lasted two hours longer, the whole of the French army would have been slain or captured; but, under cover of darkness, the greater portion made their way through the intervals of the allied troops. Many fled to Ghent, while thousands made for the French frontier. Vendome lost in killed and wounded six thousand men, and nine thousand prisoners, and his total loss exceeded twenty thousand; while the allies lost five thousand, of whom the great majority were Dutch, Danes, and Germans.
