In Chapter 1, Ralph tells Piggy that his father taught him to swim when he was five and that his father is a commander in the Navy. In Chapter 2, Ralph holds an assembly and offers the boys hope by telling them that they will be rescued because his father is searching for them. He also tells the group of boys that his father has access to a collection of maps with all the islands in the world on it. Ralph then says that sooner or later his father's ship will pass the island, and the boys will be rescued. The possibility of Ralph's father searching for the stranded group of boys provides every boy on the island with a sense of hope. The boys are relieved to hear Ralph's encouraging words and believe that they will be rescued by his father.
