"Christian IV" and his surviving troops fled to the Prince-Archbishopric and took their headquarters in "Stade". Administrator "John Frederick", in personal union also Administrator of the Prince-Bishopric of Lübeck, fled to the latter and left the rule in the Prince-Archbishopric to the Chapter and the Estates.
