A quote from “The Charge of the Light Brigade” by Tennyson that illustrates the importance of sacrifice in heroism is, “Their's not to make reply, Their's not to reason why, Their's but to do and die.”
Step-by-step explanation:
An appropriate quotation from Alfred, Lord Tennyson's poem “The Charge of the Light Brigade” that matches the topic sentence “Sacrifice is more important than success to heroism because sacrifice is needed to reach success” is “Their's not to make reply, Their's not to reason why, Their's but to do and die”. This excerpt highlights the bravery and unquestioning sacrifice of the soldiers during the doomed charge. Despite their inevitable failure, Tennyson portrays their actions as the epitome of heroism, celebrating the nobility of their sacrifice for a cause they were ordered to uphold, regardless of the outcome.
