Comment on the conversation between the characters in the strange meeting

In terms of the meaning of the poem, it describes a soldier's descent into Hell where he meets a dead enemy soldier who labels himself the man the speaker killed. The dead man talks about the horror of war and the inability for anyone but those involved in fighting to grasp the essential truth of the experience. There is more than meets the eye, however, and many critics believe that the man in hell is the soldier's "Other", or his double. A man's encounter with his double is a common trope in Romantic literature; it is seen in Shelley, Dickens, and Yeats for example.
