Battle of Drakenburg The Battle of Drakenburg (German: "Schlacht bei Drakenburg" ) took place on 23 May 1547 to the north of Nienburg, between the Protestant army of the Schmalkaldic League and the imperial troops of Eric II, Duke of Brunswick-Lüneburg, Prince of Calenberg. It resulted in an imperial defeat. Eric was forced to swim over the Weser River to save his own life. As a consequence, the imperialists left northern Germany, contributing to freedom of religion for Lutherans and Catholics in northern Germany.
