What did African Americans jobs were during the civil war?

Many who were former slaves served in the war, because they had no money, homes, or family. The pay in the Union army was poor. The South was an even worse deal because it only offered them little more freedom than they had before. Those who had been born in the free north, continued with their lives, must likely studying or owning shops. (The north was not known for its agriculture, so it is unlikely that they worked on farms. )
