They didn't a very good job of it.I don’t think that Yankees have lost their identity. They understood and continue to understand that this country is something new in the history of the world. No matter where you are from, you can become an American and realize the American Dream. One of the complaints of southerners was that the Union Army wasn’t really American... many of them were German, Irish (heaven forbid), and even Eastern European or Italian. Gasp. Be still my heart. Why wouldn’t these people just go back where they came from?
These Yankees understood and understand that the business and duty of America is to make good on the promises of the Declaration and make sure that the definition of “all men created equal” continues to expand until that statement becomes fact. According to the Vice President of the so called CSA, the rebel government was founded on the “exact opposite” ideal.
