Harriet had a change of heart when entering the free land that caused her to come back. "I had crossed the line. I was free; but there was no one to welcome me to the land of freedom. I was a stranger in a strange land."-Harriet Tubman
This is Harriet Tubman's greatest achievement because she helped the slaves escape even though she had a open road to freedom, and convinced the slaves they were not workers giving them hope to help free other slaves from neighboring plantations.
