Oflag IV-B Koenigstein was a German POW camp for Allied officers during World War II. It was located in Festung Königstein ("Königstein Fortress") near the town of Königstein in Saxony. Camp history After the Invasion of Poland of 1939, most high-ranking Polish officers were imprisoned there. The staff officers were imprisoned in the casemates and the generals in one of the forts. The lower-ranking officers were incarcerated in the lower levels of the fortress. Despite harsh conditions in the living chambers, the officers were granted relative freedom and had a part of the fortress gardens at their disposal. Apart from Antoni Szylling and Tadeusz Piskor, who were imprisoned in Murnau, all Polish army commanders taken by the Germans in 1939 were held there.

Only one execution was to be carried out, General Gustave Mesny, shot in the neck with a bullet near Nossen. The camp was surrendered to the French General Condé on May 8, the French flag was raised over the fortress for a while. A few Russians reached the fortress on May 9, 1945. The Russians stayed only long enough to remove anything of value, and loading up the German guards, they returned to their HQ leaving the French Generals alone. A short while afterwards, a French light aircraft landed and the pilot informed them that he had come to collect General Saint Ceran of the French Air Force. The remaining inmates asked that he inform the Americans of their plight which he
