[1] The group expanded from Łódź to many other towns in the Russian partition of Poland: Warsaw, Częstochowa, Kraków, Radom, Kielce, Sosnowiec, Będzin, Ostrów, Kalisz, Żyrardów and Zgierz.

[1] The group carried out many assassinations, assaults, and burglaries targeting members of the tsarist government and the bourgeoisie; about a hundred people died due to their actions.

[1] They robbed shops, banks and trains,[1] and this financed the purchase of weaponry and supported the families of those who died in the "line of duty".

[1] The group paid attention to propaganda, distributing notes and sending letters to newspapers and the authorities.

[1] In another well-known event, one of the group members survived a three-day siege in an attic; he killed a policeman, and then left the scene in his victim's uniform.

[1] The group was inspired by the philosophy of Jan Wacław Machajski, an anti-intelligentsia advocate refusing political activity and parties, and focusing on economic struggle, as well as anarcho-communism and anarcho-syndicalism.

[4] All members had one vote during meetings, but during combat operations they selected a temporary commander whom they all swore to obey without question.

[4] Stańczyk speculates that one of the reasons that the group was and still is relatively unknown was that after the communist takeover of Poland in the aftermath of World War II, research on "terrorist" communism was strongly discouraged.
