Gestern noch auf hohen Rossen, heute durch die Brust geschossen ...
This is the text from the Reiter's Morgengesang, written by Wilhelm Hauff, who is more known as an author of German tales.

It is a beautiful melody that invites you to work against it rhythmically and to build in a great deal of minor keys, which the melancholy overall mood of this nameless rider in the morning of this completely senseless war represents.
