On 12 August 1831 Prince William II at the head of the Dutch army reached the outskirts of Leuven, where Leopold I had established his headquarters. A battle broke out in which the Belgians were pushed back over the Dijle and the Dutch took the Ijzerenberg in Herent.

Then, William learned that a French army of 70,000 under Marshal Gérard had crossed the border to aid the Belgians. In order to avoid a war with France, Prince William concluded a truce with the Belgians at Pellenberg. Fighting continued for a short time, but at 16.30 on 13 August the campaign ended.

On 13 August, as agreed in the truce, the Dutch were allowed to symbolically occupy the city under the leadership of princes William and Frederick. The princes walked through the city and drank a beer in a local inn. On 14 August the Dutch pulled back. The last Dutch troops withdrew on 20 August.
