I really enjoyed this poem - it does what I wish that all of my poems could do, and that is tell a story. I am also a big fan of history - and this poem reminds me a lot of the civil war - although I feel from that it is probably about war in a general sense more than (don't know if you had a specific war in mind when writing it - the mention of armor definitely precludes the chance of it being about the civil war) anything else.
they moan and cry
and mourn the loss
of limbs and friends and peaceful nights
this part stood out to me, and really felt true and original at the same time.
The only thing that I didn't like about the poem was the ending. The mention of
"the moon appears and men kneel
to a God they never believed in"
really seemed like it was supposed to be a focal point in the story (maybe I am reading my own thoughts into it?) but then looses its momentum as poem keeps on going.
In the end, it really reminds me of the book/movie Silent Night about the miracle Christmas truce in WW1 (the book is called Silent Night, the movie JOYEUX NOňL), but could be just me. Worth checking out though if you're interested that - the movie is very moving and encouraging.
