64521: The Trenches (Heard In The Ranks)

Scratches in the dirt?
No, that sounds much too nice.
Oh, far too nice.
Seams, rather, of a Greyback Shirt,
And we're the little lice
Wriggling about in them a week or two,
Till one day, suddenly, from the blue
Something bloody and big will come
Like---watch this fingernail and thumb!---
Squash! and he needs no twice.
