And each slow dusk a drawing-down of blinds. (14)
This quiet, beautiful image points to death in about a bazillion ways. Dusk and drawn blinds are both a sort of end or closing. Plus, the line even comes at the end of the poem; yep, the poem itself is dead, too. Plus it can be read from the soldiers' perspective, with the onset of dusk standing as the equivalent of pulling down blinds (making it night). Or it can be seen as an image of civilians reacting to the death of soldiers, either to keep out the reality of it, or to shut out the world so they can mourn in their own private ways.
