During the World War I, the buildings on the castle peninsula together with the so-called Villa Schiborr were handed over to the army. At the turn of 1914 and 1915, from November 16 to February 11, units of the Russian army stayed in the old town building. The headquarters of the 10th Army operated there. After the enemy was driven out of East Prussia, the imperial army was housed in the old town and the adjacent buildings. The headquarters of the 10th German army was located in the village. It was commanded by General Hermann von Eichhorn and Colonel Emil Hellis was the Chief of Staff. General Paul von Hindenburg and Erich Ludendorff visited the troops. Frederick Augustus III, the last king of Saxony, paid his respects with his visit.
