In 955, some Saxon counts rebelled and were banished by Duke Herman. They found refuge in Swetlastrana, a Slav town, location unknown (maybe current Berlin-Lichtenberg), where the Obodrite chiefs Nakon and Stoinegin (or Stojgnev) resided. There Herman besieged them until an agreement was reached, but an ensuing skirmish spoiled the peace. The Obodrites, Wilzes, Chrepienyani, Redarii, and Dolenzi then banded together to oppose the coming army of Gero, the king, and Liudolf, Duke of Swabia. After negotiations failed because the Germans harsh terms, the Slavs were defeated in battle on the Drosa.
