With the western surroundings of Kolberg flooded by the defenders, fighting concentrated on the eastern forefield of the fortress, where Wolfsberg sconce had been constructed on Lucadou's behalf. Aiding the defense from the nearby Baltic Sea were a British and a Swedish vessel. By late June, Napoleon massively reinforced the siege forces to bring about a decision. The siege force then also concentrated on taking the port north of the town. On 2 July, fighting ceased when Prussia had agreed on an unfavourable peace after her ally Russia suffered a decisive defeat at Friedland. Of the twenty Prussian fortresses, Kolberg was one of the few remaining in Prussian hands until the war's end. The battle became a myth in Prussia and was later used by Nazi propaganda efforts. While prior to World War II the city commemorated the defendants, it started to honor the commander of the Polish troops after 1945, when the city became part of a Polish state.
