The song talks about the soldier's love and longing for his girlfriend, with whom he always met under a lantern in front of the barracks entrance, before being sent to the front.
The German version of this song was recorded in 1939 by Lala Anderson. The same version in English was sung by the American naturalized German American Marlene Dietrich.
It was a symbol and motive for the German army during World War II, no matter what front they were on.
