About the book: 1971 / At the end of March 1919, Kolchak’s counterintelligence defeated the underground Bolshevik center in Chelyabinsk. 66 people were court-martialed. The court sentenced 32 underground fighters to death, the rest to various terms of hard labor. On the night of May 18, 1919, underground heroes were brutally murdered in the courtyard of the Ufa prison. Among them was one woman - S. A. Krivaya, a member of the Chelyabinsk underground city party committee. The book of journalist I. V. Bulatov “Sonya Krivaya” is dedicated to the blessed memory of Sofya Avseevna Krivaya».
