To start slave farms since the land was bigger than most up state
The battle you are referring to is actually called the Battle of the Ironclads. In this battle, it was the Merrimac (from the Confederacy) versus the USS Monitor (from the Union). This was the first battle between iron-fortified vessels in the Civil War. This battle ended up in a draw but represented a new form of fighting that both the Union and Confederacy had to be ready for.
Civilization? I don't know the song/poem, so according to what ai have here this is my best guess...
Sorry I can't hell more!
South Carolina and Georgia were the most dependent during slavery.
