Jack and his boys stole a car from the neighbor's garage.
Jack's group attacks the four boys in their hut because they see them as a threat to their power and control over the island. Roger, in particular, is driven by his sadistic nature and desire for domination, leading to the brutal attack on the boys in the hut.
In William Golding's novel "Lord of the Flies," it is Jack's group of savages who accompany him to steal fire from Ralph's camp. They violently attack Ralph and the other boys to steal the fire and assert their control over the island.
Jack and his followers steal piggy's glasses.
Ralph opposes Jack's violent ways. He also trying to stop the boys approaching Jack's view of the boys. Moreover, by hunting Ralph, Jack is trying to show who the real leader is and why everyone should follow him.
Piggy's glasses
Jack's boys do not attack Ralph's boys at any point in the book. Roger and Maurice accompany Jack on a night time raid on the shelters but the purpose is not 'attack' anyone but simply to steal Piggy's glasses. Even when Ralph, Samneric & Piggy go to castle rock to demand the return of Piggy's glass although they are vastly outnumbered by Jack's tribe they are not attacked.
They steal a burning branch from the fire near the huts. They steal a burning branch from the fire near the huts.
No, it is Roger and the hunters who steal the conch and take it to Castle Rock in William Golding's novel "Lord of the Flies." Jack and his followers are complicit in this action, as they become increasingly savage and unruly under Jack's leadership.
Prior to holding a feast on the beach Jack, accompanied by four hunters visited Ralph's group at the shelters. Two unnamed hunters grabbed burning braches and ran off along the beach with them. Jack, flanked by Maurice and Robert, delivered a speech inviting the rest of the boys to his feast. Later in the book Jack selected Roger and Maurice to accompany him on his raid to 'get fire' from Ralph's group, infact they stole Piggy's glasses.
Jack did not want the conch. The conch represented the democratic society and rules which the boys had tried to establish. Jack wasn't interested in democracy or anyone else's wishes. Jack simply wanted total power for himself alone. It might be more apt to ask, why didn't Jack smash the conch? Of course if he had done that it would have antagonised the other boys, who might have turned against him. Instead Jack simply weaken its power by continually redefining the limits of its authority and gradually attracting more boys into his own tribe and away from the influence of the conch.
the other boys feel like they need to jack in the group. while they are building the signal fire the boys sneak off and go and join Jack's group.
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.
