It was recorded by the medieval Polish chronicler Bishop Wincenty Kadłubek of Kraków in his Chronica seu originale regum et principum Poloniae several decades later.
The contemporary author Gallus Anonymus in his Gesta principum Polonorum, written between 1112 and 1118, mentioned several armed encounters with the Imperial forces led by King Henry V of Germany.
[1] According to Wincenty Kadłubek, the Germans were ambushed by the Polish forces and the result was a complete victory of Bolesław III Wrymouth, whereafter King Henry withdrew from Poland.
After the encounter, due to the many dead and dying left on the battlefield; Kadłubek remarked, that the "...dogs which, devouring so many corpses, fell into a mad ferocity, so that no one dared venture there."
Present-day historians are split on the issue, with some arguing that the battle was rather an unimportant skirmish, and the Chronica, written at the court of Bolesław's son Casimir II the Just almost hundred years after the event, is not fully reliable.
