“The beast struggled forward, broke the ring, and fell over the steep edge of the rock to the sand by the water. At once the crowd surged after it, poured down the rock, leapt on to the beast, screamed, struck, bit, tore. There were no words, and no movements but the tearing of teeth and claws" (Golding 153).
The beast is Simon in this situation. Jack led on the group of hunters in a assault against Simon. They hurt him is many different ways that would eventually lead to his death.
