Answer:
Lost Cause
Step-by-step explanation:
Personally I believe lost cause fits the war best because it was a fight between people of the same country. A people that had just earlier fought as one to declare freedom from an oppressive king. Even though the North technically won the war, no one truly won the war because the casualty rate was one that had never been seen before. The many names come from the different points of view (Northern Aggression, Rebellion), but in the end it comes down to a lost cause because either way the war ends there would be death and destruction.
