Why is the falling rhythm of the pattern that starts with a stressed syllable, followed by two unstressed syllables, appropriate for "The Charge of the Light Brigade."?

because of the defeat the army suffered

because six hundred soldiers returned

because of the tremendous battle fought

because the heroes found glory in the end

because of the defeat the army suffered

Explanation:

The question above is related to the military action that failed called "The Charge of the Light Brigade."

The British light cavalry, led by Lord Cardigan consisted of the "Light Brigade." However, due to miscommunication, the brigade was sent to a different artillery battery, which they were not well-prepared or well-suited to fight against. This resulted to the increased number of British casualties.

Thus, the poem used a falling rhythm in its pattern in order to show how the army suffered because of being defeated. Their defeat forced them to retreat at once.

So, this explains the answer.
