Did Jack stab Ralph in Lord of the Flies?

No, during the fight on the causeway... (quote) 'Jack made a rush and stabbed at Ralph's chest with his spear.' Ralph however managed to avoid it. After Piggy was killed Jack (quote) 'Viciously, with full intention, he hurled his spear at Ralph. The point tore the skin and flesh over Ralph's ribs, then sheared off and fell in the water.'
