How does the form of "Strange Meeting," by Wilfred Owen, relate to its content?

The Poem’ Strange Meeting’ is written as an elegy: traditionally
a form used to lament or mourn the dead. Owen is mourning the death of the narrator, curiously a
poet who we take to be Owen himself, and a soldier with whom he died in battle who identifies
himself:

 I am the
enemy you killed, my friend

This use
of antithesis and contrast occurs throughout the poem to highlight the opposites of life and
death, war and peace, friend and enemy. The effect is to draw attention to the cruel ambiguities
and senseless contradictions of war.
