In 1454, George of Poděbrady in his capacity as guardian of King Ladislaus Posthumus of Bohemia, who was still a minor, appointed Hans as Landeshauptmann of the County of Kłodzko.
Agreement could not be reached and, since the Silesian dukes were still at war with the heretic King George, Hans of Warnsdorf's soldiers began looting and pillaging villages in the Diocese of Wrocław.
This brought Broumov and Police nad Metují under the reign of Henry the Elder, who incorporated them, with permission of King Vladislav II of Bohemia into his County of Kłodzko.
[3] In 1477, Hans of Warnsdorf, together with Henry the Elder and the Bohemian noblemen William Krušina of Lichtenburg, Peter Kdulinec of Ostroměř and Christopher of Talkenberg at Talkenstein, participated in the peace talks between Bohemia and Silesia at Broumov as representatives of Vladislav II.
In the same year, King Vladislav II transferred the Silesian town of Kamienna Góra to Hans of Warnsdorf and his son-in-law Frederick of Schönburg.
In 1482, Duke Henry the Elder pledged the East Bohemian possession Vízmburk Castle (German: Wiesenburg) to Hans, but he repaid the loan three years later.
