"Lincoln took an oath to preserve the union" -- FALSE
That's what George Hazard said in the movie but it's not so. Article 2 section 1 of the constitution gives the presidential oath and it says nothing about preserving the union. It does say preserve the constitution.
"I do solemnly swear (or affirm) that I will faithfully execute the Office of President of the United States, and will to the best of my Ability, preserve, protect and defend the Constitution of the United States."
This has always been a problem for the yankees. They needed to explain why the south was not allowed to secede like the original 13 colonies seceded from england. America was founded on secession. The movie got around that by simply telling a lie.
