The siege of Danzig took place between 1655 and 1660 when a Swedish force tried to capture this important Baltic Sea port city from the Polish–Lithuanian Commonwealth during the Second Northern War. After 5 years of fighting around Danzig (Gdańsk), the Swedish force, having made little progress, surrendered.
