The article discusses the life and work of Bolesław Weszczak (1910–1977), a labourer, a prisoner of the German concentration camp in Dachau (1940–1945) and an associate of the nationalistic and neopagan “Zadruga”. It also presents the activities of the conspiratorial group he was leading. The article defends the thesis that the arrest of Weszczak was what started the series of arrests of members of the “Zadruga” in 1949.
