I’ve watched the Seasons passing slow, so slow,  
In the fields between La Bassée and Bethune;  
Primroses and the first warm day of Spring,  
Red poppy floods of June,  
August, and yellowing Autumn, so  
To Winter nights knee-deep in mud or snow,  
And you’ve been everything.  
 
Dear, you’ve been everything that I most lack  
In these soul-deadening trenches—pictures, books,  
Music, the quiet of an English wood,  
Beautiful comrade-looks,  
The narrow, bouldered mountain-track,  
The broad, full-bosomed ocean, green and black,  
And Peace, and all that’s good.
Robert Graves
