In 1942 a labor camp for Polish Jews, run by “Schmelt Organization”, was opened in the area of Ludwikowice Kłodzkie, at Wiejska Street. About 600 inmates were employed in the ammunition factory established in a closed mine. In 1944 the camp in Ludwikowice became the branch of Gross-Rosen concentration camp. The second camp, consisting of 50 baracks, sprung up, in which stayed almost 1500 inmates, who worked in the ammunition factory in Miłkowo and probably were also used to build a huge complex of the underground drifts in the hillside of Gontowa and Włodyka. Until today the fate of the inmates from the male camp is unknown. There is reason to believe that they could have been murdered and buried in one of the excavations.
