Billy Pilgrim, the hero of Slaughterhouse-Five, discovers as a soldier in World War II that he moves in the fourth dimension, detached from the sequentiality of time. Thus, he involuntarily oscillates from the present to his own death, from his post-war life back to the prisoner of war camp in Dresden, where he witnessed the destruction of the city on February 14, 1945. Vonnegut's poignant anti-war novel is a literary tour de force. In Slaughterhouse-Five, he processed his own war experiences.
