Proof of existing hell (cavatina) (in answer to Czeslaw Milosz)

As soldiers we have smelt the scorching flames
of man made hell,
witnesses to the effects of exploding
shell upon shell,
know the destruction that man can bring
only too well,
have stories to tell of a kind of hate,
when mere boys are thrown to the care of fate.
