The three survivors of the shipwreck were being driven mad
by hunger.
The Irishman, an expert navigator, told the others that if
they could row
the lifeboat for three more days they could make
landfall.
The Pole, the ship's doctor, said that they could not
possibly last that
long, that there was only one solution to the problem and
that one of them
would have to sacrifice themselves for the good of the
others.
The Englishman, the captain, said that he quite understood
and that he
would volunteer as he should have gone down with the ship
anyway.
After saying an emotional farewell to his crewmen,
the captain jumped overboard and sank without trace.
