In the previous episode of our animated historical documentary series on the Thirty Years' War we have covered Bohemian Rebellion and the battle of the White Mountain between the Catholic and Protestant forces. This new episode will see Denmark under its king Christian IV joining the war on the Protestant side and fighting a 4-year campaign against the Catholic League and Holy Roman empire armies led by Johann Tilly and Albrecht von Wallenstein. The battles of Lutter and Stralsund represented the peak of this part of the Thirty Years' War.
