Duchy of Brunswick-Lüneburg
The second largest Swedish garrison in North Germany, after Swedish Pomerania, was the twin Duchy of Bremen-Verden. For political reasons, and to prevent the Swedes from advertising and recruiting mercenaries, the Allies decided to conquer these two duchies. Denmark - Norway and Brandenburg-Prussia were joined by allies from the neighbouring imperial principalities of Münster and the Duchy of Brunswick-Lüneburg.
