Three-fifths of all black troops were former slaves. Twenty-four African Americans received the Congressional Medal of Honor for extraordinary bravery in battle. Altogether, 186,000 black soldiers served in the Union Army and another 29,000 served in the Navy, accounting for nearly 10 percent of all Union forces and 68,178 of the Union dead or missing. Indeed, it seems likely that it was the availability of large numbers of African American soldiers that allowed President Lincoln to resist demands for a negotiated peace that might have including the retention of slavery in the United States.


By early 1863, voluntary enlistments in the Union army had fallen so sharply that the federal government instituted an unpopular military draft and decided to enroll black, as well as white, troops.
