Here's an example from the poem:
> "What are the buglers blowin' for?
> To call for men to fill the square?
> To fight the foe and win renown,
> To follow him that wears the crown?"
You can see the rhyming pattern in the bolded words: to (line 1) rhymes with square (line 3), and to (line 2) rhymes with crown (line 4).
This pattern is consistent throughout the poem, creating a strong and memorable rhythm that reinforces the poem's themes of duty, justice, and the tragedy of war.
