Sources include "Antapodosis, seu rerum per Europam gestarum", written by Liutprand of Cremona, "Continuator Reginonis", "Annales Alamannici", and the necrologies of the Swabian counts Gozbert and Managolt, who were killed in this battle. The chronicle "Annalium Boiorum VII", written in the 16th century by the Bavarian humanist Johannes Aventinus, gives a detailed narration of the battle, relying on older documents which today are lost. However, he errs in dating this battle to 907, soon after the Battle of Pressburg, mistakenly locates it at Ennsburg in Bavaria, and instead of Swabians, names the Bavarians as participants.
