What goes wrong in chapter 2 lord of the flies?

The main ominous even that occurs in Chapter Two is this: After lighting the fire on top of the mountain, a massive fire breaks out in the forest. The little boy with the cream colored birthmark had been in there looking around, and the others had not known. The fire creeps down and Piggy makes the terrifying discovery and realization that that boy is not around but indeed in the flames. It is implied that he had perished in the flames, the first grotesque event of the book.
