According to some reports, the assassination attempt, as well as OZN's decreasing popularity, were a signal for both OZN and ONR "Falanga" to attempt a second military coup, on 25/26 October 1937 (days when Śmigły-Rydz was to be in Romania). The reports claim that Koc was planning some kind of "St. Bartholomew's massacre" or "Night of the Long Knives", allegedly, with Śmigły-Rydz's support, which was supposed to physically eliminate the Sanational politicians opposing OZN. The plan was to assassinate 300-1500 people and to imprison an equal number, including: Mościcki; Sławek; Kwiatkowski; Janina Prystorowa, wife of then Marshal of Senate, Aleksander Prystor; and Aleksandra Piłsudska, widow of Józef Piłsudski, with Jerzy Paciorkowski and Zygmunt Wenda leading the massacre.
