After Piłsudski's May 1926 "coup d'état", Section II intensified its engagement with Prometheism. The movement's leaders included prominent Sanation figures such as Colonel Walery Sławek and the publicist and Sejm deputy, Tadeusz Hołówko. Great importance was attached to Prometheism by Section II's successive chiefs, Colonel Tadeusz Schaetzel and Colonel Tadeusz Pełczyński, and by deputy chief Lieutenant Colonel Józef Englicht. The movement's intelligence operations were directed by Edmund Charaszkiewicz. Contacts were maintained with Ukrainians and Cossacks, and with representatives of several peoples of the Caucasus: Azeris, Armenians and Georgians.
