When he was leaving there, a certain Saxon, Kizo, boldly invaded the same burg with the aid of the Liutizi rashly enough against the king’s command, and, with the perseverance of the aforesaid Slavs, altogether unjustly subjugated it to his control contrary to human or divine law. He attempted frequent attacks of robbery in Saxony along the river Elbe. By the grace of God he fled from them into hiding, not as a victor but a like a fugitive thief.9

Kizo, who had previously been a rebel and a fugutive, voiding the faith formerly promised to the Slavs, subjected himself with his men and the aforesaid burg of Brandenburg10 to the king’s power. … In the same year, the Saxons prepared an expedition against the Slavs three times but they achieved nothing; by contrast, the Slavs wearied Saxony with frequent robberies.11

In the meantime however, while the august emperor, that is Otto III, passed through Hevaldum laying waste, the assembled Veletabi attacked unexpectedly the province of Bardengau with much plundering and burning. Seeing this, the Westphalians, whom the aforementioned emperor, proceeding on his campaign, had left to guard the province, swiftly and powerfully overtook the Liutizi and, although they were few, they laid low an innumerable multitude of pagans with such great slaughter and seized so much booty from them that the amount neither of that slaughter nor of the booty can in any way be set forth in human speech.13
