" Ralph evades the other boys who are hunting for him, then realizes that they are setting the forest on fire in order to smoke him out-and thus will destroy whatever fruit is left on the island.
Running for his life, Ralph finally collapses on the beach, where a naval officer has arrived with his ship. He thinks that the boys have only been playing games, and he scolds them for not behaving in a more organized and responsible manner as is the British custom. As the boys prepare to leave the island for home, Ralph weeps for the death of Piggy and for the end of the boys' innocence"(https://www.gradesaver.com/lord-of-the-flies/study-guide/summary)
