The duke perceiving that they were continually reinforced from the other parts of the lines, ordered the horse to charge their cavalry, which were soon broken and routed; but rallying behind their infantry, interlined with foot, and joined by fresh squadrons, they advanced again towards the allies, who were now sustained by their infantry, and moved forward to renew the charge.

After a warm though short engagement, the enemy's horse were defeated with great slaughter.
The infantry, seeing themselves abandoned in the plain, retreated in great disorder, between the villages of Heylesem and Golsteven, where they were joined by the rest of their army, and formed again in order of battle.

Meanwhile the duke of Marlborough ordered all his troops to enter the lines; and extended his right towards the great Geete before Tirlemont, where the enemy had left the battalion of Montluc, which surrendered at discretion.

In this action the confederates took the marquis d'Alegre and the count de Home, lieutenant-generals, one major-general, two brigadier-generals, with many other officers, and a great number of common soldiers; a large heap of standards, four colours, one pair of kettle-drums, and ten pieces of cannon.

In the action, as the duke of Marlborough advanced to the charge at the head of several squadrons, a Bavarian officer rode up to attack him sword in hand; but in raising himself on his stirrups to strike with the greater advantage, he fell from his horse and was immediately slain.
The body of troops commanded by monsieur d'Alegre being thus defeated with little or no loss to the confederates, the elector of Bavaria and the mareschal de Villeroy passed the great Geete and the Deule, with great expedition, and took possession of the strong camp at Parck, their left extending to Eoselser, and their right to Winselen against the height of Louvain.
