Following the end of World War II, more than 10,000 German civilians trapped in the Red Army’s way pack aboard the Wilhelm Gustloff. Soon after the ship leaves port, three Soviet torpedoes strike it, inflicting catastrophic damage and throwing passengers into the frozen waters of the Baltic. Drawing on interviews with survivors, as well as the letters and diaries of those who perished, award-wining author Cathryn Prince reconstructs this forgotten moment in history.
