that was a self-serving LIE, compounded by the lincoln regime AFTER they started losing the war & it appeared that England, France & several other nations would enter the war on the southern side.
the so-called Emancipation Proclamation was INTENTIONALLY worded so that it would NOT free any slaves in US-held areas of the south AND NOT free any northern-owned slaves.
the only MAIN CAUSE of the war was the continuing lust for dixie LIBERTY!
