Венанций Фортунат
In 531 or 532, Theuderic, his son Theudebert I, and his brother King Clotaire I of Soissons attacked the Thuringii. The Franks won a battle near the river Unstrut and took the royal seat at Scithingi (modern Burgscheidungen). Hermanfrid managed to flee, but the Franks captured his niece Radegund (see Venantius Fortunatus, "De excidio Thoringae") and his nephews.
