Answer: Escaped by train; Disguised as a sailor.
Step-by-step explanation:
Fredrick Douglass was one of the most prominent faces in the Abolitionist movement as well as being a vocal supporter of women's rights. He had escaped to freedom in the North from Baltimore about suffering many hardships normal to enslaved people in the South.
He pulled off the escape by climbing a train from Baltimore to Philadelphia.
His disguise was that of a sailor as he wore a red shirt, a tarpaulin hat, and a black scarf that was tied loosely around his neck.
He had extensive knowledge of shipping and so was able to get through when questioned by the train conductor.
