explain why free and enslaved african americans fought for and against the
patriots

During the American Revolutionary War, many African American slaves participated as soldiers on both sides of the conflict. Most of them, some 20,000, did so for the British side, hoping for the Dunmore's Proclamation, which guaranteed freedom for slaves to join the Loyalist cause. In turn, some 10,000 joined the Patriot forces, although in this case many of them did so sent by their owners, who supported the independence of the United States. However, many of the African Americans who fought on the Patriot side were released once independence was obtained.
