The Rhume then flows in northwesterly direction through the municipalities of Gieboldehausen, Katlenburg-Lindau and Northeim.
On the Saxon side, in addition to Count Otto of Northeim and Bishop Burchard II von Halberstadt, were Magnus Billung, meanwhile Duke of Saxony, Margrave Lothair Udo II of the Nordmark and Count Gebhard of Supplinburg, who was killed in battle, as well as the Saxon count palatine Frederick II of Goseck and Count Dietrich II of Katlenburg.
It flows in that direction through Osterode-Dorste before entering the westward-flowing Rhume between the villages of Berka and Elvershausen, both part of the borough of Katlenburg-Lindau in the district of Northeim.
