This inquiry examines the experiences of African Americans during the Civil War, those who served in the Union army and enslaved, formerly enslaved, and freed blacks in the south and north. The contributions of African Americans to the war effort were considerable. About 179,000 black soldiers (10% of the Union Army) served in the U.S. Army and 19,000 served in the Navy. This despite the fact that African Americans were only 1.5% of the population in northern states in the war years. Forty thousand black soldiers died over the course of the war.
