Shocking as the Titanic's sinking undoubtedly is, one particular ship's demise has gone almost completely unnoticed yet stands as one of the worst acts of man's inhumanity to man, even during wartime. The ship was the Wilhelm Gusthloff.
Exactly why the Titanic is remembered and the far worse tragedy in the Baltic forgotten is discussed here:

The plain fact of the matter is that the war on the Eastern front does not figure in mainstream Western histories. It was a different war.
Even so, the Titanic itself was a symptom of the struggle for supremacy between the Kaiser and his uncle, Edward VII.
Whilst the Titanic was a milestone in this foolishness the Wilhelm Gustloff and its tragic passengers were the part of the conclusion.
