Marlborough's army remained on the ground they had won, collecting and caring for the wounded of both armies.
Two days later, Berwick's corps joined Vendome, and that of Eugene marched into Marlborough's camp.

In spite of the loss that he had suffered at Oudenarde, this reinforcement raised Vendome's army to over one hundred and ten thousand men, which was about the same force as Marlborough had under his command.
After Eugene had joined him, standing as he did between Vendome's army and Paris, Marlborough proposed that the enemy's fortresses should be neglected, and that the army should march directly on Paris.

The movement might have been attended with success, but was of so daring a description that even Eugene opposed it, while the commanders of the Dutch, Danes, and Prussians were unanimously against it; and he consequently decided to lay siege to Lille--a tremendous undertaking, for Lille was considered the strongest fortress in France, and Vendome, with over a hundred thousand men, was within a couple of days' march of it.
His dispositions were made with extreme care, and a tremendous convoy of heavy artillery, ammunition, and provisions was brought up from Ostend, without the French being able to interfere with its progress.

Marlborough, with his British contingent and the Hanoverians, was to cover the operations of the siege, which was to be undertaken by Prince Eugene with the rest of the allied army.
Vendome marched at once with his army, and, making a circuit, placed himself between Lille and Paris, deserting his recent conquests in Ypres, Ghent, and Bruges, all of which fell into the hands of the allies..
