Answer: 2) The regiment charges the enemy lines even though they think they will be defeated.
Step-by-step explanation:
I am unsure as to which novel this is from but the second option shows more courage than the first.
Courage in times of war means fighting against the enemy even though you know you may not survive. It is courageous because you did not give up and run away but rather stayed to fulfil your duty to your country.
The regiment charging even though they thought they would be defeated shows courage because they are not running away but rather staying to fight for their country at the risk of their lives.
