No sooner was this design made manifest, than Marlborough followed with all his forces, with the double design of raising the investment of Oudenarde, and if possible forcing the enemy to give battle, under the disadvantage of doing so in a retreat. Anxious to improve their advantage, the Allied generals pushed forward with the utmost expedition, hoping to come up with the enemy when his columns and baggage were close upon the Scheldt, or in the very act of crossing that river. Colonel Cadogan, with a strong advanced guard, was pushed forward by daybreak on the 11th towards the Scheldt which he reached by eleven, and immediately threw bridges over, across which the whole cavalry and twelve battalions of foot were immediately thrown. They advanced to the summit of the plateau on the left bank of the river, and formed in battle array, the infantry opposite Eynes, the cavalry extending on the left towards Schaerken. Advancing slowly on in this regular array down the course of the river on its left bank, Cadogan was not long of coming in sight of the French rearguard under Biron, with whom he had some sharp skirmishing. Meanwhile, Marlborough and Eugene were pressing the passage at the bridges with all imaginable activity; but the greater part of their army had not yet got across. The main body was still half a league from the Scheldt, and the huge clouds of dust which arose from the passage of the artillery and carriages in that direction, inspired Vendome with the hope that he might cut off the advanced guard which was over the Scheldt, before the bulk of the Allied forces could get across to their relief. With this view he halted his troops, and drew them up hastily in order of battle. This brought on the great and glorious action which followed, towards the due understanding of which, a description of the theatre of combat is indispensable.
