Polish–Swedish War (1626–1629)

The Polish–Swedish War (1626–1629) was the last in a series fought by Sweden and the Polish–Lithuanian Commonwealth between 1600 and 1629. In July 1626, Gustavus Adolphus landed in Polish Prussia in an attempt to capture Gdańsk, but neither side could win a decisive advantage and the war became a stalemate.
