Sylvia Plath wrote the poem "Daddy" shortly before her death by suicide in 1963. The poem uses the metaphor of a train journey to represent Plath working through her complex feelings about her father, who died when she was young, as well as her estranged husband, Ted Hughes. Through vivid, surreal imagery and references to death and World War 2, Plath conveys her deep-seated anger and desire to break free of the men who dominated her life. The intensely personal work is considered a prime example of confessional poetry and gives insight into Plath's inner psychological state near the end of her life.
