Why did African Americans join the British army during the war

Many African Americans joined the British army during war as they believed that they would get their civil rights and gradually achieve freedom.

Explanation:

In those days the Africans were treated as slaves and property. Their rights were denied and they had to live a life of slavery. But during British they were considered as humans and were given freedom.

This gave confidence among the African Americans to join British so that they could get freedom from slavery. They were treated as humans and also were placed in higher ranks in the military.
