Die Soldaten (The Soldiers) is a four act opera in German by German composer Bernd Alois Zimmermann, based on the 1776 play by Jakob Michael Reinhold Lenz. It is dedicated to Hans Rosbaud.[1] Zimmermann himself faithfully adapted the play into the libretto, the only changes to the text being repeats and small cuts. It is the composer's only completed opera and is considered an important work of the second half of the 20th century. -- Wikipedia
