[3] As a consequence of the fall of the city, Prussia lost its last major port on the Baltic Coast,[4] while at the same time the Russian forces were able to take winter quarters in Pomerania.

Though Russian reinforcements brought up Palmenbach's strength to 5,000 the following month, heavy rain and storms rendered successful construction of siege works impossible.

In July, a Russian expedition commanded by Gottlob Heinrich Tottleben advanced into Brandenburg-Prussian Pomerania but, upon reaching the Rega valley, was ordered to the Silesian battlefields.

[9] On 27 August, Kolberg was bombarded from the sea by the entire Russian Baltic fleet: 21 ships of line, three frigates and three bomb vessels, all of which had arrived the day before.

[9] While the siege was sluggish,[8] Frederick II of Prussia ordered a force of 3,800 commanded by Major-General Paul von Werner to disengage from the battles in Silesia and instead relieve Kolberg, which was some 340 kilometres (210 mi) to the North.

Rumyantsev, who lost naval support on 9 October when the Russian warships sailed home because of bad weather, was reinforced by part of Alexander Borisovich Buturlin's army the same month.

His cavalry, commanded by Gustav Berg, cut off Prussian communication lines, countered excursions of Württemberg's 2,700 horse and captured at least four of their units.

[15] Another Russian achievement was that Rumyantsev's siege kept Platen's forces in check, whom hard-pressed Frederick had expected to aid him in Silesia once Kolberg was relieved.

[8] By the time of the sieges, Russian Tsaress Elizabeth of Russia was suffering from an illness, which led to her death on 25 December 1761 (OS) or 5 January 1762 (NS).

[5] Peter, who had opposed Russia's involvement in the Seven Years' War, ceased the hostilities with Prussia at once and, by the terms of the Treaty of Saint Petersburg, returned to her all occupied territories (including Kolberg) as well as providing Frederick with 20,000 troops.

[5] Deprived of their Russian ally, the Austrian House of Habsburg was unwilling to continue the war on its own[5] and returned to the status quo ante with Prussia in the Treaty of Hubertusburg.
