In honor of Black History Month, I thought it appropriate to talk about the part African-Americans played during the Civil War. Everyone knows that President Lincoln signed into law the Emancipation Proclamation on January 1, 1863. What they likely don't know is that he had no intention to free slaves in northern states, or states that he had jurisdiction in. In fact, in his home state of Illinois, freed slaves were disallowed, and Lincoln did nothing to reverse the fact.
During the War Between the States, the Union army enlisted black soldiers. However, most of those poor guys were forced to hard labor, and didn't engage in battles. By the war's end, African Americans constituted less that one percent of the U.S. population, yet made up 10 percent of the Union army. Altogether, 180,000 black men enlisted, which was more than 85 percent of those eligible.
On the Confederate side, General Patrick Cleburne advocated enlisting slaves to fight for the cause in return for their freedom. But after he was killed in 1864, the idea fizzled until it was again raised in November 1864 by President Jefferson Davis. The Confederate Congress authorized enlisting 300,000 black soldiers in March 1865, but the war ended the following month. Speculation arises that if the war had ended sooner, Lincoln probably would not have signed the Emancipation Proclamation into law. The Confederacy missed the opportunity to tap into their largest source of manpower, and were thus so outnumbered that they were doomed to fail.
