IN midnight sleep, of many a face of anguish, 
   Of the look at first of the mortally wounded--of that indescribable 
         look; 
   Of the dead on their backs, with arms extended wide, 
       I dream, I dream, I dream. 
 
 
   Of scenes of nature, fields and mountains; 
   Of skies, so beauteous after a storm--and at night the moon so 
         unearthly bright, 
   Shining sweetly, shining down, where we dig the trenches and gather 
         the heaps, 
       I dream, I dream, I dream. 
 
 
   Long, long have they pass'd--faces and trenches and fields; 
   Where through the carnage I moved with a callous composure--or away 
         from the fallen, 
   Onward I sped at the time--But now of their forms at night, 
       I dream, I dream, I dream.                                     10
