Der heimliche Aufmarsch (English: "The Secret Deployment") is a poem by Erich Weinert written in 1929. In 1930, Wladimir Vogel composed music to it, and there is one extant recording of this original melody with Weinert himself providing the vocals. In 1931, Ernst Busch sang a version of the song at the end of the film Hell on Earth by Victor Trivas. The most famous version is the 1938 remake with a new arrangement by Hanns Eisler, which can be heard at Communist Party rallies from that point forward.
