What beautiul images you've conjured, esp. in the first line. I also like "If my ears were stronger..." The only suggestion I have is in the second stanza, where you say "there must be a story for so much...". Somehow the word "story" doesn't seem right. Perhaps "word" or "name?" There are stories about this kind of carnage, but nobody to my knowledge has ever assigned a single word to it.

Brilliant opening Stephan, waking the 'dead' on L2, after giving life to the butterflies in the first line.
I tend to agree with Josie on the 'story' thing - purpose to, meaning behind, legend of? and I'd also use 'such' rather than 'so much' (carnage tends to imply scale anyway).
"the images of summers embers" - that doesn't sound/read right, it should be either "summers' embers" (possesive plural with apostrophe), "summer's embers" (the embers of this particular summer) or just summer embers (summer in general, as these images are common to all summers)
Perhaps a comma after "no headstones" (as you're using [inconsistent] punctuation throughout)
"is sanctified only by me" reads awkwardly - perhaps "is sanctified by me alone" would sound better?
What are 'footprints of snow'? Snow itself doesn't leave footprints, so maybe "footprints in snow" would be better, although 'in' and 'atop' might be a problem...not sure about that.
I looked up 'taupe(s)', but couldn't find anything - what are 'taupes'?
"beige of missed opportunities" is a wonderful application of colour...great start, and finish, and the whole thing is seasonally redolent and full of strategic contrasts and contradictions...wistfully atmospheric.

I will only quibble with the footprints of snow. As snow melts, it can, and often does leave oddly shaped 'prints' where shade or drifting leave some parts unmelted. It does look like footprints.

Ok - yes, I agree, a melt can give the impression of imprints, though not necessarily 'foot' prints - that's not important, 'footprints' is fine if that was your impression, or the impression you intended to make. I read this -
"This holy ground
is sanctified by only me, and the footprints
of snow..."
and assumed that they were associated with you (your steps) in some way. So for me, ambiguous, but now you've explained, I can see the intention. I'm a bit pedantic that way :>
*footnote* So, I've read it over again - now I can see it's you and the footprints...I do so much 'reading into' that I forget how to just read :>
