An Imperial army commanded by Albrecht von Wallenstein left besieged Stralsund to confront Christian IV.

Christian IV of Denmark-Norway had started the Danish-Norwegian intervention in the Thirty Years' War by invading the Holy Roman Empire in 1625.

[10] The Emperor Ferdinand II gave Wallenstein the Duchy of Mecklenburg in January, and promoted him "General of the Oceanic and Baltic Seas" in April 1628.

[13] The Pomeranian port of Stralsund, some 70 kilometers west of Wolgast, refused to accept the Capitulation of Franzburg and with Danish and Swedish support successfully resisted Wallenstein's siege.

[15] On 11 August,[2] Christian IV of Denmark-Norway with 7,000 troops[4] landed on Usedom, separated from the town of Wolgast by the Peenestrom sound, and occupied the island.

[16] After the Imperial garrison was expelled, Christian IV was met by an overwhelming support of the local population to turn Wolgast into a fortress like Stralsund.

[11] The defeat at Wolgast, ending the most ambitious operation of the Danish 1628 amphibious assault series,[13] was the decisive factor that led Christian IV to negotiate the Peace of Lübeck with Ferdinand II, Holy Roman Emperor.

[13] In 1630, Gustavus Adolphus of Sweden started the Swedish invasion of the Holy Roman Empire, landing on Usedom near Wolgast - in the same spot as Christian IV did before.

[22] While his success was longer lasting, he would return to Wolgast on 15 July 1633 in a casket, when his body was embarked for the final transfer to Sweden.
