U-9 Weddigen

U-9 Weddigen is a 1927 German silent war film directed by Heinz Paul and starring Carl de Vogt, Mathilde Sussin and Fritz Alberti. The film is based on the exploits of the submarine SM U-9 under the command of Otto Weddigen during the First World War. It is similar in theme to the previous year's Our Emden, which also depicted the Imperial German Navy in heroic terms.
