Military necessity rather than abolitionist conviction forced Union anti-slavery moves

Evidence

After the Confederates humiliated Union soldiers in the First Battle of Bull Run in northern Virginia on July 21, 1861, proposals about enslaved Africans’ potential war utility besieged Congress and the Lincoln administration. Initially, Congress passed a resolution emphatically declaring that the war was not “for the purpose of overthrowing or interfering with the rights and or established institutions of these states.” But war demands soon changed their calculations. — Ibram X. Kendi, Stamped from the Beginning, 576

Categorization

• XREF: Supports Kendi’s core causal inversion: self-interested war utility (not moral ideas) drove the Confiscation Act — policy from interest, then ideas follow to justify it. — connects to: Slavery is a continuing state of war, not a legitimate compact — John Locke, Second Treatise of Government, 32
• QUESTION: Reader wants to test the inversion against cases where ideas seem to precede policy — this is a clean example where self-interest (war necessity) clearly drove the policy shift, no abolitionist morality needed.
