Зембицкое княжество
From about 1425 onwards, Hussite forces campaigned the lands and used Hummel Castle as a base for their attacks. They laid siege to Karpień Castle and devastated the towns of Bystrzyca, Radków and Nowa Ruda. A major battle with the royal Bohemian forces led by the Kladsko governor Půta III of Častolovice and the Silesian duke John I of Münsterberg was fought at Stary Wielisław on 27 December 1428. Duke John was killed in action and Půta received his Duchy of Münsterberg as well as Kladsko and the adjacent Silesian lands of Ząbkowice as a pledge from the hands of Emperor Sigismund. After Půta's death, his widow Anne of Colditz sold Kladsko Land to the former Hussite leader Hynek Krušina of Lichtenburg in September 1440, and married him three weeks later.
