There had been absent from this great meeting a Saxon chieftain, called Wittikind, son of Wernekind, King of the Saxons at the north of the Elbe. He had espoused the sister of Siegfried, King of the Danes; and he was the friend of Ratbod, King of the Frisians. A true chieftain at heart as well as by descent, he was made to be the hero of the Saxons just as, seven centuries before, the Cheruscan Herman (Arminius) had been the hero of the Germans. Instead of repairing to Paderborn, Wittikind had left Saxony, and taken refuge with his brother-in-law, the King of the Danes. Thence he encouraged his Saxon compatriots, some to persevere in their resistance, others to repent them of their show of submission. War began again; and Wittikind hastened back to take part in it. In 778 the Saxons advanced as far as the Rhine; but, “not having been able to cross this river,” says Eginhard, “they set themselves to lay waste with fire and sword all the towns and all the villages from the city of Duitz (opposite Cologne) as far as the confluence of the Moselle. The churches as well as the houses were laid in ruins from top to bottom. The enemy, in his frenzy, spared neither age nor sex, wishing to show thereby that he had invaded the territory of the Franks, not for plunder, but for revenge!” For three years the struggle continued, more confined in area, but more and more obstinate. Many of the Saxon tribes submitted; many Saxons were baptized; and Siegfried, King of the Danes, sent to Charlemagne a deputation, as if to treat for peace. Wittikind had left Denmark; but he had gone across to her neighbors, the Northmen; and, thence reentering Saxony, he kindled there an insurrection as fierce as it was unexpected. In 782 two of Charlemagne’s lieutenants were beaten on the banks of the Weser, and killed in the battle, “together with four counts and twenty leaders, the noblest in the army; indeed, the Franks were nearly all exterminated. At news of this disaster,” says Eginhard, “Charlemagne, without losing a moment, reassembled an army and set out for Saxony. He summoned into his presence all the chieftains of the Saxons, and demanded of them who had been the promoters of the revolt. All agreed in denouncing Wittikind as the author of this treason. But as they could not deliver him up, because immediately after his sudden attack he had taken refuge with the Northmen, those who, at his instigation, had been accomplices in the crime, were placed, to the number of four thousand five hundred, in the hands of the King; and, by his order, all had their heads cut off the same day, at a place called Werden, on the river Aller. After this deed of vengeance the King retired to Thionville to pass the winter there.”
