He was killed in 807, in a battle against Gerold, duke of Suabia, and his tomb is still to be seen at Ratisbonne.

Several families of Germany hold him for their ancestor; and some French genealogists have, without solid ground, discovered in him the grandfather of Robert the Strong, great-grandfather of Hugh Capet.
However that may be, after making peace with Wittikind, Charlemagne had still, for several years, many insurrections to repress and much rigor to exercise in Saxony, including the removal of certain Saxon peoplets out of their country and the establishment of foreign colonists in the territories thus become vacant; but the great war was at an end, and Charlemagne might consider Saxony incorporated in his dominions.
[Illustration: THE SUBMISSION OF WITTIKIND----218] He had still, in Germany and all around, many enemies to fight and many campaigns to re-open.

Even amongst the Germanic populations, which were regarded as reduced under the sway of the king of the Franks, some, the Frisons and Saxons as well as others, were continually agitating for the recovery of their independence.

Farther off towards the north, east, and south, people differing in origin and language--Avars, Huns, Slavons, Bulgarians, Danes, and Northmen--were still pressing or beginning to press upon the frontiers of the Frankish dominion, for the purpose of either penetrating within or settling at the threshold as powerful and formidable neighbors.

Charlemagne had plenty to do, with the view at one time of checking their incursions and at another of destroying or hurling back to a distance their settlements; and he brought his usual vigor and perseverance to bear on this second struggle.
