Invasion of Rügen

The invasion of Rügen of 22 to 24 September 1678 was a military operation in the Swedish-Brandenburg War, or Scanian War, that ended with the annexation of the Swedish-ruled island of Rügen by the Allies – Brandenburg-Prussia and Denmark – for just under a year before it was restored by treaty to Sweden.

The operation was a prelude to the long-planned Siege of Stralsund that followed shortly thereafter.
