Planning and preparation By the time Mazanik had begun working as a maid in the Kube mansion, partisans had already been planning his assassination. After receiving authorization from Moscow the partisan detachments in the Minsk area began preparing to liquidate him. On 22 July 1943 they detonated a bomb in a Minsk theater, killing around 70 German soldiers; however, Kube had left the theater just minutes before the bomb went off. On 6 September 1943 after partisans attacked a banquet for German officers they managed to kill 36 high-ranking officials and officers, but because Kube was not present for unknown reasons they did not kill him that day, nor did they when they attempted to ambush him on a road on which he often traveled. On 8 August 1943, Tatyana Kalita, one of the maids who had worked for Kube, introduced Mazanik to other members of a partisan unit that had been given the task of killing Kube, including
Nadezhda Troyan under the pseudonym "Kanskaya" and a man named Artur working for the partisan detachment known as "Dyadi Koli". In a series of meetings, Mazanik agreed to kill Kube, either using an explosive or poison, but not before waiting for her sister Valentina Shchutskoi to confirm the identity of
Mariya Osipova and Nikolai Pokhlebayev, who had introduced Osipova to Mazanik while Troyan was trying to get her to agree to a task. Before carrying out the assassination they made plans for her family to be evacuated from Minsk because they would undoubtedly face retaliation. She then met with several other partisans, and after a few bumps in the road Mariya Osipova provided Mazanik with a bomb and a poison capsule in case she was caught. Originally they planned to poison Kube with arsenic, but Mazanik did not want to do that because there were children in Kube's mansion who might eat the food they would poison.
Execution of the plot On the night of 21 September 1943 Mazanik, with the assistance of her sister Valentina, set the bomb to go off in 24 hours. At 6:30 the next morning she wrapped the small bomb in a handkerchief and placed it in her purse before leaving to observe a mass execution. Meanwhile, Valentina and the rest of her family were packing their possessions into carts and leaving Minsk for partisan-controlled areas of the forest. The guards standing at the entrance to Kube's mansion did not pay much attention to the maids they knew worked for Kube, but nevertheless tried to see what was under the handkerchief in Mazanik's bag; however, she managed to stop them from lifting it enough to see the bomb by interrupting them by saying it held a gift for Kube's wife Anita. After entering the house Mazanik went to the bathroom and hid the bomb under her dress. Late at night on 12 October all of the conspirators in the plot were flown out of Belarus to Moscow, and after writing the final report on the mission the partisans were interrogated by
Vsevolod Merkulov,
Bogdan Kobulov, and
Fyodor Kuznetsov at the
Lubyanka. On 29 October 1943 the three main conspirators, Mazanik, Troyan, and Osipova, were awarded the title
Hero of the Soviet Union. == Postwar life ==
