How did slaves who were still on the plantations during the war the union cause? 1) they prayed for the war to end. 2) they ate less food so that more food could be sent to the union soldiers. 3) they passed information to the union soldiers through a network they established. 4) they slowed down their work production or did not work. 5) all of the above

The best answer between all the possibilities is 4) They slowed down their work production or did not work. As the war grew in scope and duration, however, enslaved African Americans took advantage of the turmoil created by the war to run away, engage in sabotage, to serve as a guide and join the Union war effort, or pursue their own interests. Also, they slowed down their work product or did not work, as some plantation-owners confessed.
