During the Seven Years' War, the Prussian-held town of Kolberg in Brandenburg-Prussian Pomerania (now Kołobrzeg) was besieged by Russian forces three times. The first two sieges, in late 1759 and from 26 August to 18 September 1760, were unsuccessful. A final and successful siege took place from August to December 1761. In the sieges of 1760 and 1761, the Russian forces were supported by Swedish auxiliaries.
