According to Fredegar, who seems to have been personally interested in this event, the last which he recorded, both were the victims of divine judgement, for they had sworn friendship in holy places and had subsequently despoiled land to enrich themselves and made war on each other. After the battle at Autun, Willibad's tent had been pillaged and his wealth dispersed. A hoard of coins found at Buis in Saône-et-Loire have been hypothesized to be from his treasure.
As reported by Fredegar, who seems to have had a vested interest in this case, both parties suffered the consequences of divine punishment, having sworn an oath of friendship in sacred sites and subsequently exploited land for personal gain, leading them into conflict. After the Autun battle, Willibad's tent was plundered, and his wealth was scattered. A hoard of coins found at Buis has been suggested as a possible origin of his treasure.
