12. This rebellion having been put down, the king next made an attack upon a tribe of the Slavs, whom we call the Wiltzi, in their own tongue, Welatabi.... The cause of this war was the attacks which the Welatabi were making upon the Abodriti, who were formerly allies of the Franks, and their refusal to desist from these attacks at the command of the king. There is a great gulf [Baltic Sea] extending east from the western ocean [Atlantic], whose length is unknown, but whose width nowhere exceeds one hundred miles, and is in many places narrower. Many tribes dwell along its shores: on the northern shore and in the islands, the Danes and the Swedes, whom we call Northmen; on the southern shore, the Slavs and the Aisti, and other tribes, among whom are these Welatabi. These latter were defeated in a single campaign and have never dared to revolt again. 13. The greatest of all the wars of Karl except the Saxon war, was that against the Avars and the Huns.... The king himself led one expedition against them into Pannonia, where they dwelt, but intrusted the later ones to his son Pippin and to the dukes and counts of the neighboring regions. The war lasted for eight years, and the bloody character of it is shown by the fact that to-day Pannonia is uninhabited and the site of the Khan's palace is a desert, containing no trace of former human habitation. The whole nobility of the Huns was destroyed in the course of this war, and all the treasure of the Avars carried away by the Franks.{47} ... 14. ... His last war was waged against the Danes or Northmen. Beginning with small piratical raids, they had grown so bold that they attacked the shores of Gaul and Germany with large fleets, and their king, Godfrid, planned the conquest of Germany itself. He already claimed the Frisians and Saxons as his subjects, and had subjected the Abodriti and made them tributary. He even boasted that he would shortly proceed to Aachen and attack Karl himself. And indeed there was real danger that he might undertake this, but he was slain by one of his own followers and the danger passed.
