When Tristan gets mortally wounded, he sends his servant for Isolde, since she's the only one who can cure him. If Isolde comes back with the servant, he is supposed to put up white sails, and black sails if she doesn't come. White sails are up, but Tristan's wife lies and says that the sails are black, and Tristan dies of a broken heart.
