What do Jack and Maurice and Roger take from Ralphs group after attacking Ralph and Piggy in lord of the flies?

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)
