Square. Sławek delivered weapons to some participants, and the rally ended in an exchange of fire with the police. It was the first act of armed resistance in Congress Poland since the January Uprising. During the 1905 Congress of the PPS, Sławek was elected to the Central Workers Committee (CKR), as its youngest member. His main duty was coordination of local party chambers in southwestern corner of Congress Poland. Sławek himself never became a true Socialist: he regarded this party as the only real organization which would bring back independent Poland. During the Revolution of 1905, he was a key member of Combat Organization of the Polish Socialist Party, and participant in numerous missions. On September 10, 1905, he was arrested and sent to the Warsaw Citadel. Russian authorities planned to send him to Siberia, but on October 19, amnesty was declared, and on November 4, 1905, Sławek was released. He continued his activities: during a raid on a train near Milanówek (June 9, 1906), a bomb exploded in his hand, injuring his head and chest. Sławek lost his left eye, three fingers in his right hand and two fingers in his left hand. Furthermore, he permanently lost hearing in his left ear, and for the rest of his life, Sławek wore a beard, which covered numerous scars on his face. Arrested again, he was acquitted by court and ordered to leave the Russian Empire. Sławek left for Kraków, then located in Austrian Galicia. There, he underwent two operations, which improved his health. Nevertheless, he suffered from severe depression, caused both by the injuries, and the death of his wife. Józef Piłsudski ordered him to oversee party finances. In 1908, he was sent to Paris, and after his return, took part in the legendary Bezdany raid. On June 1, 1909, Sławek, already a member of the Union of Active Struggle (ZWC), was arrested by the Austrian authorities. He was released after two weeks, with help from Austrian military intelligence (Hauptkundschaftstelle, HK-Stelle), which cooperated with the leadership of the ZWC. The Austrians highly appreciated the information on Russian army, stationed in Congress Poland. In exchange, the HK-Stelle allowed the ZWC to carry out its activities. World War I Sławek was one of the chief advisors of Piłsudski. In mid-1914, he joined 1st Brigade, Polish Legions, but in August, he did not march with First Cadre Company to Congress Poland, remaining in
