‘American need to stop buying the fairy tales they have been taught in gov’t schools. From an illegal military invasion of the Southern states, to illegal imprisonment of newspaper men that did not agree with him, to using troops with cannons on New Yorkers against the draft, to the support for massive rape-murder-pillage in the valley of Virginia and the “march to the sea”, Lincoln betrayed everything American and today would be a tried as a world class war criminal.’
The long-accepted death toll of 620,000 between 1861 and 1865, cited by historians since 1900, was reconsidered by Binghamton University history demographics professor J. David Hacker. In research published in Civil War History, Prof Hacker said he's uncovered evidence that the toll is actually closer to 750,000.

Those who betrayed America were Jeff Davis, Lee, Jackson, et al. Their insurrection was ruled illegal in Texas v. White.
Sadly, the victorious Union showed too much mercy, so that treason was not so harshly punished as it should have been.
