Kłodzko, Poland
During World War II, the fortress was changed into a prison administered by the Reich Ministry of Justice and Wehrmacht.[15][16] It housed prisoners of various nationalities, including Allied prisoners of war. In 1941–1942, many prisoners were sent to forced labour in various locations in German-occupied Poland, Czechoslovakia and Austria, and in 1942–1943, six FStGA field penal battalions (1, 7, 10, 13, 16, 20) were established in the town and afterwards relocated to the Eastern Front.[16] In November 1942 and January 1943, the town was the site of a German trial of 39 members of the Związek Orła Białego Polish resistance organization, 18 of which were sentenced to death.[17] 198 prisoners were deported from the prison to various Nazi concentration camps, chiefly Gross-Rosen.[18] Presumably only two men, a Pole and a Russian, managed to escape from the prison (on 23 September 1944).[19] Beginning in 1944, the casemates housed the AEG arms factory evacuated from Łódź, in which some 1,500 Poles were subjected to slave labour. The stronghold was turned into a subcamp of the Gross-Rosen concentration camp. The Germans also established and operated eight forced labour subcamps of the Stalag VIII-B/344 POW camp in the town.[20]
In January and February 1945, many prisoners from other locations, including Katowice, Racibórz, Brzeg and Nysa, were brought to the local prison either during death marches or transports, and many were then sent further west to Bautzen.[21]
The town itself was not damaged by the war and was taken over by the Soviet Red Army without a major battle on 9 May 1945. However, all the bridges, except the Gothic stone bridge of 1390, were destroyed.
