The Gustloff sinking and its namesake
In the novel, the Soviet submarine S-13 under Alexander Marinesko torpedoes the Wilhelm Gustloff on 30 January 1945, a former 'Strength Through Joy' liner evacuating refugees, wounded soldiers and naval personnel from East Prussia, and thousands die, many of them children. The ship bore the name of Wilhelm Gustloff, a German Nazi official working in Switzerland whom the Jewish student David Frankfurter shot in Davos in 1936, after which the regime honoured him as a party martyr.
