Siege of Stralsund (1628)

The Siege of Stralsund, 13 May to 4 August 1628, took place during the Thirty Years' War when an Imperial Army under Albrecht von Wallenstein attempted to capture the key Baltic Sea port of Stralsund. Then an independent city and part of the Hanseatic League, Stralsund was initially reinforced by small numbers of Scots mercenaries in Danish service, before Gustavus Adolphus of Sweden sent a larger force under Alexander Leslie.
