“The Emancipation Proclamation is perhaps the most misunderstood of the documents that have shaped American history. Contrary to legend, Lincoln did not free the nearly four million slaves with a stroke of his pen. It had no bearing on slaves in the four border states, since they were not in rebellion. It also exempted certain parts of the Confederacy occupied by the Union. All told, it left perhaps 750,000 slaves in bondage. But the remaining 3.1 million, it declared, “are, and henceforward shall be free.” The proclamation did not end slavery in the United States on the day it was issued. Indeed, it could not even be enforced in most of the areas where it applied, which were under Confederate control. But it ensured the eventual death of slavery — assuming the Union won the war. Were the Confederacy to emerge victorious, slavery, in one form or another, would undoubtedly have lasted a long time.... Nonetheless, the proclamation marked a dramatic transformation in the nature of the Civil War and in Lincoln’s own approach to the problem of slavery. No longer did he seek the consent of slave holders. The proclamation was immediate, not gradual, contained no mention of compensation for owners, and made no reference to colonization. In it, Lincoln addressed blacks directly, not as property subject to the will of others but as men and women whose loyalty the Union must earn. For the first time, he welcomed black soldiers into the Union Army; over the next two years some 200,000 black men would serve in the Army and Navy, playing a critical role in achieving Union victory. And Lincoln urged freed slaves to go to work for “reasonable wages” — in the United States. He never again mentioned colonization in public. Having made the decision, Lincoln did not look back. In 1864, with casualties mounting, there was talk of a compromise peace. Some urged Lincoln to rescind the proclamation, in which case, they believed, the South could be persuaded to return to the Union. Lincoln refused. Were he to do so, he told one visitor, “I should be damned in time and eternity.””
