The Theft of Fire: Jack's tribe raids Ralph's camp to steal Piggy's glasses, the only remaining tool for making fire, effectively stripping Ralph's group of their power and hope for rescue.
The Death of Piggy: Ralph and Piggy travel to Castle Rock to demand the return of the glasses. Roger, Jack's lieutenant, releases a boulder that kills Piggy and shatters the conch shell.
The Manhunt: With the conch destroyed and Piggy dead, Ralph is the last vestige of order. Jack orders a full-scale manhunt to find and kill Ralph, setting the entire island on fire to smoke him out.
The Arrival of the Navy: Just as Ralph is cornered on the beach by the murderous tribe, a British naval officer appears, attracted by the smoke from the fire intended to kill Ralph.
The Loss of Innocence: Confronted by the reality of their actions and the presence of an adult authority figure, the boys stop their pursuit and begin to weep for the 'end of innocence' and the 'darkness of man's heart.'
The Final Irony: The officer, a soldier in a global war, expresses disappointment in the boys' behavior, failing to recognize that his own 'civilized' world is engaged in the same violent savagery on a larger scale.
Identify Turning Points: Always highlight the transition from the 'beast' as an external threat (the parachutist) to an internal reality (Simon's realization).
Analyze Symbolic Deaths: Note that Simon's death represents the loss of spiritual truth, while Piggy's death represents the total destruction of intellectualism and democratic order.
The Irony of the Fire: Be prepared to discuss how the fire, which was Ralph's symbol of hope and rescue, ultimately becomes Jack's tool of destruction that inadvertently leads to their rescue.
Check the Ending: Avoid describing the rescue as a 'happy ending.' It is a rescue from the island but a tragic realization of the permanent loss of childhood innocence.
