The Battle of Dirschau (also known as Battle of Tczew) took place in the summer of 1627 (17–18 August) and was one of the battles of the Polish–Swedish War (1626–29). The Polish forces led by Crown Field Hetman Stanisław Koniecpolski met with troops commanded by Swedish King Gustavus Adolphus of Sweden. Gustavus Adolphus was wounded in the battle, which ended inconclusively. Fighting in Prussia ended in a stalemate for that year, and would not resume until 1628.
