Hey You!
The correct answer to your question is: Stated that freed slaves could join the U.S Military.
(This is because an estimated 180,000 freed slaves joined the military, and about 18,000 joined the navy).
And that's your answer! ^

Slaves first arrived in Mississippi in French ships that came from West Africa where they had bought the slaves, and then brought them to Mississippi to sell/trade. Hope it helps!
