Frank,
I think you have a fine poem here. It's not a 'throwaway' one, as many competition entries are (either topical or very specific) - it's definitely a 'keeper' and deserves to be seen in an anthology, beside Fenton's original photo, which you've captured the esssence of very well, IMO.
Maybe it's worth enquiring whether anyone's planning to produce a new volume of war-related poems?
Meanwhile, it would be great to see it, and Roger's, on the
Speccie page
