Преображенский лейб-гвардии полк
The Imperial Guard played a key role in suppressing the 1905 Revolution, most particularly at Saint Petersburg on Sunday, 22 (O.S. 9) January 1905 (Bloody Sunday). The Semyonovsky Regiment subsequently repressed widespread disturbances in Moscow. However, a full battalion of the Preobrazhensky Regiment mutinied in June 1906.
