Excerpt that is missing: My country is Kiltartan Cross,
My countrymen Kiltartan's poor,
No likely end could bring them loss

Explanation:
This poem is how an Irish soldier is feeling during World War I and about what he is thinking. Soldiers are often thinking about their home and country during the war.
- It is written by W. B. Yeats and he used parallelism in this poem to show the readers how strong and big it is soldiers' love for his Irish nationality.
We can see parallelism in "My country is Kiltartan Cross" and "My countrymen Kiltartan's poor." where he is talking about the place in Western Ireland.
