Viborg, Denmark
In December 1534, the army of Johan Rantzau defeated the peasant army which had retreated to Aalborg and strengthened the defenses of the city. After a hard battle, Rantzau's army overcame the defenses, sacked the city and killed as many as 2,000 people. Clement managed to escape, but was betrayed and captured by his enemies. He was kept in prison until the end of the civil war and was then executed by breaking on the wheel in Viborg, Denmark.
