Charge of the Light Brigade
By Alfred Tennyson

Half a league, half a league,
Half a league onward,
All in the valley of Death
Rode the six hundred.
"Forward the Light Brigade !
Charge for the guns !" he said.
Into the valley of Death
Rode the six hundred.
"Forward, the Light Brigade!"
Was there a man dismay'd ?
Not tho' the soldier knew
Some one had blunder'd.
Theirs not to make reply,
Theirs not to reason why,
Theirs but to do and die.
Into the valley of Death
Rode the six hundred.

Which of the following statements is not true ?

The military discipline teaches the soldiers :

The correct answer is to act tactfully in the battlefield.

Step-by-Step Explanation:

1. Analyze the Extract:
The lines in the poem highlight strict military discipline and unconditional obedience:
"Theirs not to make reply,
Theirs not to reason why,
Theirs but to do and die."

2. Evaluate the Options:
- "to do and die.": This is directly stated in the lines ("Theirs but to do and die"), so it is true according to the text.
- "to obey their commander's order.": The poem emphasizes charging on command ("Forward, the Light Brigade!") regardless of a blunder, making this true.
- "not to ask any question.": This corresponds directly to "Theirs not to make reply / Theirs not to reason why", making this true.
- "to act tactfully in the battlefield.": The poem does not describe the soldiers questioning or strategically adapting tactfully on their own; rather, it highlights blind obedience to orders even when someone has blunder'd. Thus, this statement is not true in the context of the poem's description of military discipline.

3. Conclusion:
Since the question asks for the statement that is not true, the correct choice is to act tactfully in the battlefield.
