African American Slaves

Explanation: African Slaves did fight for both sides, but if they had to pick between the British or the Americans, the slaves would've picked the British. Due to the fact that the British got rid of slavery a long time ago. The Americans would most likely set some slaves free for fighting for their side, but in the end, most would go back to slavery.
