The Civil War, like many wars, began with neither side having a clear idea about how long and costly it would be. Each side expected to win and win quickly. Confederate strategy was to

a
destroy Washington, D.C., force slaves to relocate to Cuba, restore the Union
b
invade the North, conquer Canada, outlaw slavery within its borders
c
blockade all southern ports, acquire more territory, slowly abolish slavery
d
separate from the Union, protect property, be recognized as an independent country

D, obviously!
