The Saxon Fratricidal War first broke out between Frederick II, Elector of Saxony and Duke William III in 1446 when they were unable to resolve their dispute in the Division of Altenburg. Frederick proved stronger, and William brought in forces from Bohemia, including Hussites. Frederick's forces were led by various commanders and captains, including Kunz von Kaufungen. Kunz won a victory at Gera while commanding Frederick's forces and occupied the small town, and in return William's forces and Bohemian allies pillaged the area around Kaufungen. Kunz had much of his property destroyed, was captured by Bohemian forces, and forced to pay 4,000 golden gulden for his freedom, a very large sum for the time. Neither side could gain a decisive advantage and the war dragged on for five years of "ruinous confusion" before ending on 27 January 1451, when a peace was reached at Naumburg.
