I really don't think the South had a plan to win.
Lee squandered many advantages he had in winning the war.
I think after every battle the South was suprised that the North did not give in and allow them to be a nation.
It was more of a plan not to be defeated in the field and loose the war.
Had some of the advantages been exploited early in the war and Lee invaded the North or threateded DC, Del, NJ, NY, Eastern PA, or other parts of New England the population that was willing to send sons, husbands, brothers and fathers to the battlefields in the South would not be willing to have those battle fields in the North.
William, are you planning on warming up the way back machine with Mr Peabody 150 years and changing our history?
