The purpose of the War between the States was to kill the idea of secession. Slavery was secondary. Lincoln once supported an amendment to enshrine slavery if it would “save the Union”. It was not the war to free the slaves but to enslave the free.
Lincoln ordered at least one escaped slave returned to his master in UNION state Missouri. The Emancipation Proclamation ONLY applied to the SOUTHERN states, NOT Missouri or Maryland, Delaware or Kentucky. To this day Mississippi folks consider Kentucky as “North”.
