What triggered the duel at Sedan?

 title: 'A classical temple with columns.'

The duel at Sedan between the Baron des Guerres (or d’Aguerres) and the Lord de Fendilles was triggered by a quarrel[1]. The source mentions, 'To settlement their affair...applied to King Henry to appoint them a place for combat'[1]. It also states that the subject of the quarrel 'was one unsuited for any other form of discussion'[1]. Therefore, this led to a duel being fought at Sedan[1].
