The mythology serves purposes darker than sentiment, nothing more so than the currently popular, and arrantly nonsensical, assertion that Lee freed his inherited slaves in 1862 before the war was over, while Grant kept his until the Thirteenth Amendment freed them in 1865. The subtext is transparent. If Southerner Lee freed his slaves while Northerner Grant kept his, then secession and the war that followed can hardly have had anything to do with slavery and must instead have been over the tariff or state rights, or some other handy pretext invented to cloak slavery's pivotal role.
