Bede tells that Ebroin waylaid an Englishman returning from Rome, for fear that the Byzantine Emperor (Constans II, residing in Syracuse) was plotting an alliance against his rule.
Ebroin endeavoured to maintain the union of Neustria and Burgundy, but the great Burgundian nobles wished to remain independent.
They rose under bishop Leodegar (or Léger) of Autun and Adalrich, Duke of Alsace and offered the crown to Theuderic's elder brother Childeric II, then ruling in Austrasia.
[2] When Childeric II was murdered at Bondi that year, by a disaffected Frank, Theoderic III was reinstalled as king in Neustria with Leudesius as his mayor.
About 675 Ebroin reimposed his authority over Neustria and most of Burgundy, and induced the Duke of Champagne and the Bishops of Châlons and Valence to attack Autun.
After the battle, Duke Martin of Laon, who had made it back to his city, was lured to Ecry with false assurances on the pretext of negotiations with Theuderic.
Tales of Ebroin's infamy were also found useful by the Austrasians, whose own ambitious mayoral family commissioned the continuations to the chronicle of Fredegar.
