In 924 Vikings made a fresh series of raids into West Francia. From the Loire Valley they threatened Hugh the Great, brother of Queen Emma, but Rudolph did nothing. Soon they attacked Burgundy, the domain of Rudolph's brother. They were repulsed, and moved on to Melun, where they threatened the royal lands. Joined only by his ecclesiastic vassals and Herbert, he recruited troops in Burgundy, while Hugh the Great was convinced to join him. After the Vikings left, the Normans, whom Charles the Simple had settled in Duchy of Normandy in 911, began ravaging that whole region. Herbert and Arnulf I of Flanders joined Rudolph and together they took Eu, but were ambushed near Fauquembergues where the king was wounded, the count of Ponthieu killed, and many Normans left dead on the field.
