In March 1947 at his apartment in the American occupational zone of Vienna Kachorovsky too loudly celebrated his birthday and upset neighbors called a police. The Austrian law officers handed the detained over the Soviet military or chekists. The Ministry of State Security (MGB) Counter-Intelligence Department (SMERSH) of the Central Group of Forces that was based in Austria was already interested in Kachorovsky and several months before tried to detain him, but the strong man then managed to fight them off and flee. After interrogations of Kachorovsky in MGB became aware who were Roman Novosad and Vasyl Vyshyvanyi, while the latter one obviously had previously been trapped in field of vision of the Soviet secret service. After several months of hunting after, they first detained Novosad and then Vyshyvanyi, de facto Novosad was detained on 14 June and Habsburg on 26 August. In most documents appear dates not detention, but rather arrest when against them have already taken preventive measures 26 June and 22 September respectively. Snyder writes that Kachorovsky soon was executed, while it is unclear from what source is that information.
