The Frankish force was led by Arnulf of Carinthia. The Franks successfully repelled the Viking assault and it is reported that the bodies of dead Northmen blocked the run of the river (ita ut cadaveribus interceptum alveum amnis siccum appareret). After the success, Arnulf built a castle on a small island in the Dijle River. The Annales Fuldenses, the source that mentions this battle is the first source that mentions the city of Leuven (), which was at that time called Loven. The battle is also mentioned in the Anglo-Saxon Chronicle.
