Question

Why does Tennyson most likely make the fifth stanza longer than the third stanza of "The Charge of the Light Brigade"? to make each stanza in the poem slightly longer than the previous one to show that the fifth stanza is more critical in understanding the poem to draw the reader’s focus to the fourth stanza where the battle occurs to highlight the aftermath of the fierce battle waged in the fourth stanza

Answer 1

I believe it is the last one (to draw the readers focus to the forth stanza where the battle occurs....)

Answer 2

to make each stanza in the poem slightly longer than the previous one
