The poet uses repetition with the word 'they're' to refer to the survivors of the war. The whole poem is one large sentence broken up by ',' and '-'. The poem starts with a sentence and ends in the same sentence, just more developed.
L - Language
The meaning of the poem was to emphasise how many soldiers have fallen in war and are being brought back home. The title 'Homecoming' could also suggest that the soldiers are being waited for when they return.
E - Emotion
The image intended to be created in the readers head is dark, and helps the reader to feel the pain of the war by creating the image of the dead bodies 'piled on the hulls of Grants'.
The poet used concise language to get his meaning across and doesn't develop on his ideas much. Alliteration is also in place to emphasise what the poet is trying to say.
The poet uses the subject he is talking about to bring out empathy within the reader. The sensitive topic of dead bodies in piles could also make the reader feel guilt as it is often referred to that those soldiers died for us and our freedom.
