The Battle of Wolgast was an engagement in the Thirty Years' War, fought on 22 August (O.S.) or 2 September (N.S.) 1628 near Wolgast, Duchy of Pomerania, Germany. Danish forces of Christian IV of Denmark had made landfall on Usedom and the adjacent mainland, and expelled the imperial occupation forces. An Imperial army commanded by Albrecht von Wallenstein left besieged Stralsund to confront Christian IV. Ultimately, the Danish forces were defeated. Christian IV and a faction of his landing force were able to escape by ship.
