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

As they near Fort Mose's entrance, they view it as a pathway to liberation. "Copper Sun" is a work of historical fiction authored by Sharon M. Draper. It revolves around a young girl named Amari, who is taken captive by her tribe's neighbors, the Ashanti, and sold into slavery. Amari, a fifteen-year-old from the Ewe tribe, is joined by Polly, an indentured white girl taken to Derbyshire Plantation along with her, and Tidbit, the four-year-old son of Teenie, a kitchen slave. Together, they are sent to the auction by Doctor Hoskins, who eventually liberates them near the jungle and instructs them to head north towards Fort Mose. They undertake a grueling trek through the jungle for days without sustenance, finally reaching the Fort, which they perceive as their escape from oppression, slavery, and abuse.
