[Q]: Question: What was the original name of the Służba Bezpieczeństwa? Passage:On 30 June 1943 he was arrested by the Gestapo in Warsaw and sent to Berlin. Rowecki was arrested due to his betrayal by Ludwik Kalkstein "Hanka", Eugeniusz Swierczewski "Genes" and Blanka Kaczorowska "Sroka" who were Gestapo agents. All of them were members of the Home Army but in fact collaborated with the Gestapo. Swierczewski, Kalkstein and Kaczorowska were sentenced to death for high treason by the Secret War Tribunal of the Polish Secret State. The sentence on Eugeniusz Swierczewski was carried out by troops commanded by Stefan Rys ("Jozef"). They hanged Swierczewski in the basement of the house at 74 Krochmalna Street in Warsaw. Kalkstein received protection from the Gestapo and was not harmed. He fought in a Waffen SS unit during the Warsaw Uprising of 1944 under the name of Konrad Stark. After the war, he worked for the Polish Radio station in Szczecin and was later recruited as an agent by the Urząd Bezpieczeństwa. In 1982, he emigrated to France; he died in 1994. Blanka Kaczorowska also survived the war. Her death sentence was not carried out because she was pregnant. After the war, she also worked as a secret agent for the Urząd Bezpieczeństwa and later for the renamed Służba Bezpieczeństwa. She emigrated to France in 1971. She died in 2002
