To lift the curse, the crew needed to return all 882 medallions to the chest and offer their blood. Their shipmate Bootstrap Bill Turner believed that they deserved the curse as punishment for their mutiny, and sent one coin to his son, Will. In retaliation, Barbossa tied Bootstrap to a cannon and threw him overboard. For years, Barbossa searched for the last coin and the child of Bootstrap Bill, both of which were needed to break the curse. Elizabeth Swann takes the medallion from Will Turner. Barbossa, believing her to be Bootstrap Bill's daughter, kidnaps her. He later learns that Will is Bootstrap Bill's child; he captures Will and plans to execute him to break the curse. As Jack and Barbossa duel, Will breaks the curse by returning the last coin and offering his blood. Barbossa bleeds out from his wounds.
