The Battle of Gniew or the Battle of Mewe was fought during the Polish–Swedish War (1626–1629), between Sweden and the Polish–Lithuanian Commonwealth from 22 September with initial skirmishes, to the main battle of October 1, 1626. Both the Swedish and Polish army were commanded by their kings – Gustavus Adolphus of Sweden and Sigismund III Vasa. The battle ended indecisively. However, Polish and Swedish armies had different objectives. Sigismund Vasa wanted to protect Gdańsk from besieging. Gustav had to protect Gniew, which was important for the prestige of his army. The battle ended in a Swedish victory.
