Focko Ukena - a former henchman of Ocko - thrashed the combined Bremen-Oldenburg cavalry force, after Count Dietrich of Oldenburg deserted his allies during the battle.[1] Count Johann von Rietberg, the second son of Otto II of Rietberg and Conrad X of Diepholz fell in battle.[2] and Archbishop Nicholas of Oldenburg-Delmenhorst was captured,[1] but released after negotiations with the Bremen town council.
