During the battle, the Frisian army is beaten and King Poppo is killed.^[1] The Franks gain control of the Frisian lands west of the Lauwers (Netherlands), and begin plundering the pagan sanctuaries. The Frisians become Frankish vassals, apart from the tribes living in East Frisia in present-day Germany.
