wounded. After that he joined the Polish 1st Lithuanian–Belarusian Division which at this time had taken over Minsk and was heading east with offensive (see: Polish–Soviet War); he took part in Battle of Warsaw (1920). From 7th of April 1920 to 10th of January 1921, he studied in army officers school Szkoła Podchorążych Piechoty as Belarusian in the 29th United Polish-Belarusian class. He was demobilised on May 12, 1921. After leaving the army Sergiusz Piasecki found himself in a very difficult situation. He had no education, and his father's estate remained abroad. He had walked the distance from Minsk to Wilno to visit his brother, who lived in poverty himself and couldn't help Sergiusz. He traveled around Wileńszczyzna hustling, falsifying bank cheques and acting in pornographic photoshoots. He has described this episode of his life in a book The Life of a Disarmed Man. Ambiguities In the monograph about his life, work and legend, researcher Krzysztof Polechoński noted that most available data about Piasecki's whereabouts often do not correspond to reality, not to mention the claims made by the writer himself. Perhaps the discrepancies came from his work as intelligence agent, but there is no way to confirm many of his personal stories. Piasecki's addresses in Vilnius are not available and neither are the registers of houses in which he lived. His personal documents in possession of Piasecki's son: such as the copy of a marriage certificate with Jadwiga Waszkiewicz or the birth certificate of his son Władysław Tomaszewicz are falsifications, as revealed by Polechoński himself after a search performed in Vilnius archives. It is not possible to say whether his evacuation card is authentic. There is no photo of him in the prisoners' photo archives of Łukiszki penitentiary. There is no proof of his residency amongst the Vilnius city dwellers. He might have stayed in a hotel. Self-generated legend Sławomir Andruszkiewicz noted, that Piasecki boasted in "The Tower of Babel" about his many false papers, thus making it difficult even for himself to pull out the correct one every time. The researchers are unable to prove any of his family names, surnames and pseudonyms used during the war. It is impossible to explain, said Andruszkiewicz, why so many of his official statements contain made up facts. It is not known what underground organizations Piasecki belonged to as there is no proof of any. According to his autobiographical writing, at
