Caesar was a horse owned by a horse livery in Calabar, on the West Coast of Africa. Captain Jack Sparrow intended to ride to Roger Dalton's farm to help Tarek, a slave, escape. Jack originally intended on renting a horse wagon, but when he found that they are out, he settled for a horse, a completely new creature to him. In the evening, Caesar didn't respond well to Jack and even threw him off onto the ground of the street. When Jack tried to get the horse to listen once more, the horse began to run away. Jack also ran, and Ayisha scolded him, revealing that she knew English. She then took control of the horse and led them to the Dalton farm to rescue her friend.
