The Battle of the Unstrut River is said to have been fought in 531 CE near the river Unstrut when the king of Francia, Theuderic I decisively defeated the Thuringian army led by their king Hermanfrid. Thuringia was subjugated in 530 CE, soon after the battle. The battle was so decisive that it is said that the Franks were able cross the river by walking over the corpses of their foes. After the battle, Chlothar took Radegund as a wife as part of his war booty.
