At this exact time, Billy becomes "un-un-unstuck in time" and has flashbacks from his former and future life. Billy and the other prisoners are transported into Germany. By 1945, the prisoners have arrived in the German city of Dresden to work in "contract labor" (forced labor). The Germans hold Billy and his fellow prisoners in an empty slaughterhouse called "Schlachthof-fünf" ("slaughterhouse five"). During the extensive bombing of Dresden by the Allies, German guards hide with the prisoners in the slaughterhouse, which is partially underground and well-protected from the damage on the surface. As a result, they are among the few survivors of the firestorm that rages in the city between February 13 and 15, 1945. After V-E Day in May 1945, Billy is transferred to the United States and receives his honorable discharge in July 1945.
