piggy's glasses
Well in chapter 10 Jack and his tribe of savages invade Ralph's tribe (made of up Ralph, Sam and Eric, Piggy, and one/two littluns) in order to steal Piggy's glasses, which is overall the power to start a fire on the island. Jack might have mentioned this plan in chapter 9 so I'm hoping this is the right answer to your question.
Ralph and Piggy confront Jack to try and reason with him and bring the group back together. Their plan fails because Jack is consumed by power and control, and he refuses to listen to reason or cooperate with them. Jack's actions ultimately lead to chaos and violence within the group.
Piggy and Ralph's plan to confront Jack and the other boys at Castle Rock is flawed because they underestimate Jack's savagery and willingness to resort to violence. Additionally, they lack a cohesive strategy and fail to anticipate the consequences of their actions, leading to a tragic outcome.
Piggy and Ralph are both characters in Lord of the Flies. The problem with Piggy and Ralph's plane is that it goes down and there are no grown-ups around to care for them.
Piggy is cautious and unsure about Ralph's decision to climb the scar, as he is concerned about the possible dangers and risks involved. He tries to dissuade Ralph from climbing the scar, suggesting an alternate course of action. Ultimately, Piggy's concerns are not heeded, and Ralph continues with his plan.
Ralph rejects Piggy's suggestion to blow the conch to call for a meeting after the assembly breaks down. Ralph believes that the conch has no power to control the boys anymore and that they need a more concrete plan to maintain order on the island.
In chapter 10: the Shell and the Glasses Jack informs his tribe, and I quote, "But tomorrow we'll hunt and when we've got meat we'll have a feast---" Bill then puts up his hand and asks, "What'll we use for lighting the fire?" Jack blushed but then informed his tribe that, "We'll take fire from the others." Eventually Jack did set out, with Roger and Maurice, to raid Ralph's camp, not for fire but for the means by which fire could be made, namely Piggy's glasses.
Jack used Piggy's glasses by focusing the sunlight through the lenses onto dry leaves and twigs to create a spark and ignite a fire. Piggy's glasses acted as a magnifying glass, harnessing the sun's rays to start the fire.
They took Piggy´s glasses, but didn´t take the conch. The conch is only a symbol of authority and has power only when the society agrees that it does. For Jack, the shell is, now, only a shell. The glasses, however, give him real power because he is the only one with the ability to start a fire. "He was a chief now, in truth." (Pg. 168)
Jack and Roger have sharpened a stick at both ends to hunt and kill Ralph. Their plan is to hunt Ralph like they did with the sow, to terrify him and flush him out. Samneric warn Ralph that they are being hunted and that Jack's tribe will sharpen a stick at both ends and have Roger guard the way in.
Samneric because they where forced to join Jack Mildrew's tribe and they told Ralph about Jack's plan to search and destroy Ralph.
Piggy and Ralph's plan to build a signal fire is flawed because they don't prioritize maintaining it properly. They struggle to keep the fire going, resulting in missed opportunities for rescue. Additionally, their lack of supervision allows the fire to spiral out of control and contribute to a disastrous outcome.
