Our animated historical documentary series on the Thirty Years' War comes to the end with a video on the battles of Lens and Prague of 1648 and the subsequent peace of Westphalia which ended the conflict. In the aftermath of the battle of Zusmarshausen, the Holy Roman Empire attempts to drive the attention away from Bavaria by attacking in Arras, leading to the battle of Lens between Conde and Beck, while the Swedes under Konigsmarck attack Prague to get a better deal during the peace conference.
