In November 1626, the Swedish Empire recruited troops in Pomerania even though the duke had disapproved. In February 1627, Swedish troops crossed the duchy for Poland, an imperial ally Sweden was at war with. In July, imperial troops crossed into the duchy near Pyritz (now Pyrzyce). To prevent the pending occupation, duke Bogislaw XIV offered 60,000 Talers in October, later raised to 200,000 Talers. Unimpressed Albrecht von Wallenstein instead ordered Hans-Georg von Arnim to occupy all Pomeranian ports and to confiscate all vessels.
