After the death of his father, Hunald I allied himself with free Lombardy. However, Odo had ambiguously left the kingdom jointly to his two sons, Hunald and Hatto. The latter, loyal to Francia, now went to war with his brother over full possession. Victorious, Hunald blinded and imprisoned his brother, only to be so stricken by conscience that he resigned and entered the church as a monk to do penance. The story is told in Annales Mettenses priores. His son Waifer took an early inheritance, becoming duke of Aquitaine and ratified the alliance with Lombardy. Waifer decided to honour it, repeating his father's decision, which he justified by arguing that any agreements with Charles Martel became invalid on Martel's death. Since Aquitaine was now Pepin's inheritance because of the earlier assistance that was given by Charles Martel, according to some the latter and his son, the young Charles, hunted down Waifer, who could only conduct a guerrilla war, and executed him.
