Chapter 22: Oudenarde. 

The trumpet call which summoned Rupert and his friends to horse was, as he suspected, an indication that there was a general movement of the troops in front. 

Vendome had declined to attack the allies in the position they had taken up, but had moved by his right to Braine le Leude, a village close to the ground on which, more than a hundred years later, Waterloo was fought, and whence he threatened alike Louvain and Brussels. Marlborough moved his army on a parallel line to Anderleet. No sooner had he arrived there, than he found that Vendome was still moving towards his right--a proof that Louvain was really the object of the attack. Again the allied troops were set in motion, and all night, through torrents of rain, they tramped wearily along, until at daybreak they were in position at Parc, covering the fortress of Louvain. Vendome, finding himself anticipated, fell back to Braine le Leude without firing a shot. 

But though Marlborough had so far foiled the enemy, it was clear that he was not in a condition to take the offensive before the arrival of Prince Eugene, who would, he trusted, be able to come to his assistance; and for weeks the armies watched each other without movement. 

On the 4th of July, Vendome suddenly marched from Braine le Leude, intending to capture the fortress of Oudenarde. Small bodies of troops were sent off at the same time to Ghent and Bruges, whose inhabitants rose and admitted the French. Marlborough, seeing the danger which threatened the very important fortress of Oudenarde, sent orders to Lord Chandos who commanded at Ath, to collect all the small garrisons in the neighbourhood, and to throw himself into Oudenarde. This was done before Vendome could reach the place, which was thus secured against a coup de main. Vendome invested the fortress, brought up his siege train from Tournay, and moved towards Lessines with his main army, to cover the siege.
