Hermann Kirchhoff, a military historian and admiral, recounts the life and military career of the officer and submarine commander Otto Weddigen through diaries, letters, and posthumous papers. Weddigen gained fame for sinking three English warships within a few hours in 1914. This event is considered a breakthrough in modern submarine warfare. The following year, Weddigen's submarine, U 29, was sunk by an English battleship. No one survived the attack, which ultimately cemented Weddigen's status as a legend. Illustrated with numerous images.
