Cud nad Wisłą (1921)

Eastern Borderlands, 1919. The Bolsheviks, taking part in the Polish-Russian war, appear at the Granowski manor house. It's a story based on the war of 1920, which ended with the Battle of Warsaw going down in history as the "Miracle on the Vistula". The film was commissioned by the Propaganda Department of the Ministry of Military Affairs and has survived only in fragments (just 53 minutes out of the 2-hour-long film).
