Flossenbürg was established in 1938 near the German town of the same name, about 8 miles from Weiden. Built at relatively high elevation, the camp endured a cold climate for most of the year. The location of the camp made additional construction difficult and as a result overcrowding increased and was only slightly alleviated by making the prisoners work and sleep in shifts. Unhygienic conditions inevitably led to epidemic disease and the prevalence of lice. Poor rations of inadequate food resulted in malnutrition and lowered resistance to disease. This situation deteriorated further in the last months of the war with increased food shortages.
Flossenbürg had its own SS Death Head´s Battalion led by SS Untersturmfuhrer Bruno Skierka, whose activities earned him a death sentence (later commuted) from an American military court after the war.
Flossenbürg was originally a men’s camp, although there were subcamps for women during the war and some female political prisoners were brought in to work in a camp brothel located near the cellblock. As of 1st January 1945 Flossenbürg and its subcamps had a total of 3,046 guards (including 521 female warders) responsible for preventing the escape of 40,437 prisoners (including 11,191 women).
Separated from other prisoners were a number of Allied POWs. The NCO in charge of the cellblock from June to December 1944 recalled finding about 15 Allied officers when he arrived there “ two of whom were shot in June or later on, at different times”. A Yugoslav prisoner recalled seeing 13 naked bodies hanging in the cellblock courtyard near the end of the war, one tattooed with the name “Mary” in English spelling. An SS man told him they were Americans and Britons. An Austrian prisoner also recalled seeing these corpses and ascertained that they were Anglo American POWs. A Swiss prisoner imprisoned in the cellblock from February 1944 testified that American and British POWs were brought to the camp in spring 1944 and held in darkened cells.
Between 1938 and 1945 approximately 30,000 prisoners died in Flossenbürg, roughly three quarters of them during the last nine months of the war. As many as 1,500 people were brought to Flossenbürg for the execution of extrajudicial death sentences ordered by the Reich Security Main Office. There were also some public hangings on the roll call square, and one such killing took place in December 1944 in front of the assembled prisoners next to a decorated Christmas tree.
According to a U.S. postwar tabulation (Nuremberg Document NO-393), there were 155 Spanish citizens at Flossenbürg, of whom 60 died.
Jews were shown to be transported to Flossenburg on these dates: 8/13/44, 9/22/44, 10/12/44. I’m sure there were others, but that’s all my research found as of now.
