Footage showing Hitler's triumphant journey across Germany is accompanied by the song "Wenn die soldaten", a German march that was actually written in the late 19th century, and famously sung by Marlene Dietrich. Although unconnected with the Nazi cause, the song has been identified with it in other films. In the TV Movie "Hitler's S.S.: Portrait in Evil" (1985), the song plays over scenes of SS officers mobilizing on the eve of "The Night of Long Knives", the infamous 1934 purge of the Sturmabteilung.
