seeing no chances of victory, Duke Louis II of Brieg entered into an arrangement with John, under which he was compelled to not interfere with the movements of enemy troops. However, for unknown reasons, John broke the ceasefire, and with this he began his participation in the war. John died on 27 August 1428 in the battle of Altwilmsdorf (Stary Wielisław), in the Valley of Glatz (Kłodzko), fighting against the Hussite leader Jan Kralovca. The cause of the disaster was a thoughtless attack of the Hussite troops, or earthwork built wagons from the battle. It's unknown where John was buried. On the alleged place of the Duke's death was built a Chapel during 1904–1905 designed by Ludwig Schneider. After his death, and according to the treaty of 1343, the Duchy of Münsterberg was annexed by the Kingdom of Bohemia.
