A war consist of constant fighting and the civil war was best known because of the US fight not other countries but themselves. I don't believe anyone was deported to Mississippi because that happened to be a free state and the civil war was about freedom for African-Americans. The battles tended to take place at farms and villages so B is out. And though women did fight during the war, the fact that they were joining didn't make that much of a difference for the war (respectfully). Now it makes a difference but then it didn't. Plus with C, the war could be won easily. People surrender and the war is over. I believe this strategy was used at Fort Wagner.
