How do Polly, Tidbit and Amari approach the entrance to Fort Mose?

They approach the entrance to Fort Mose as a road to freedom.

Explanation:

"Copper Sun" is a historicl fiction written by Sharon M. Drapper. The story is about a girl named Amari, who is captured by her neighbouring tribe, Ashanti and sold into slavery.

Amari was a fifteen-year-old girl who belonged to Ewe tribe. Polly was an indentured white girl, who was brought to Derbyshire Plantation along with Amari. Tidbit was a four-year-old son of Teenie, a kitchen slave.

They all were sent to auction with Doctor Hoskins. But he frees them near the jungle and ask them to go to the north, to Fort Mose. They all journey in thhe jungle tirelessly and without food for many days to reach the Fort Mose.

They all approached the Fort Mose as a road to their freedom; freedom from oppression, freedom from slavery, freedom from being abused.
