Szare Szeregi
Radom was a center of Polish resistance, with various organizations, such as Service for Poland's Victory, , Union of Armed Struggle, Bataliony Chłopskie, Grey Ranks and numerous Home Army units operating in the area. The resistance carried out various actions, which included sabotage, stealing weapons, secret education, etc. Poles were even able to produce weapons for Polish partisans in the local arms factory, even though it was seized by the Germans. In 1942, the Germans discovered the activity, and then publicly hanged 50 Poles, including 26 employees of the arms factory, and a pregnant woman. Scouts from the Gray Ranks who worked at the local post office stole and destroyed anonymous letters to the Gestapo, thus possibly saving many lives. Two German doctors from a local hospital helped the Polish resistance, for which one was even arrested and sent to a concentration camp. In April 1943, the resistance successfully assassinated the chief of the local German police.
