Slaughterhouse-Five, or The Children's Crusade: A Duty-Dance with Death (1969) is a satirical novel by Kurt Vonnegut about World War II experiences and journeys through time of a chaplain's assistant named Billy Pilgrim. It is generally recognized as Vonnegut's most influential and popular work. Vonnegut's use of the firebombing of Dresden as a central event makes the novel semi-autobiographical, because he was present then.
