Frodo was lying face upward on the ground and the monster was bending over him, so intent upon her victim that she took no heed of Sam and his cries, until he was close at hand. As he rushed up he saw that Frodo was already bound in cords, wound about him from ankle to shoulder, and the monster with her great forelegs was beginning half to lift, half to drag his body away.
On the near side of him lay, gleaming on the ground, his elven-blade, where it had fallen useless from his grasp. Sam did not wait to wonder what was to be done, or whether he was brave, or loyal, or filled with rage. He sprang forward with a yell, and seized his master's sword in his left hand. Then he charged. No onslaught more fierce was ever seen in the savage world of beasts; where some desperate small creature armed with little teeth alone, will spring upon a tower of horn and hide that stands above its fallen mate.
Disturbed as if out of some gloating dream by his small yell she turned slowly the dreadful malice of her glance upon him. But almost before she was aware that a fury was upon her greater than any she had known in countless years, the shining sword bit upon her foot and shore away the claw. Sam sprang in, inside the arches of her legs, and with a quick upthrust of his other hand stabbed at the clustered eyes upon her lowered head. One great eye went dark.
Now the miserable creature was right under her, for the moment out of the reach of her sting and of her claws. Her vast belly was above him with its putrid light, and the stench of it almost smote him down. Still his fury held for one more blow, and before she could sink upon him, smothering him and all his little impudence of courage, he slashed the bright elven-blade across her with desperate strength.
But Shelob was not as dragons are, no softer spot had she save only her eyes. Knobbed and pitted with corruption was her age-old hide, but ever thickened from within with layer on layer of evil growth. The blade scored it with a dreadful gash, but those hideous folds could not be pierced by any strength of men, not though Elf or Dwarf should forge the steel or the hand of Beren or of T畆in wield it. She yielded to the stroke, and then heaved up the great bag of her belly high above Sam's head. Poison frothed and bubbled from the wound. Now splaying her legs she drove her huge bulk down on him again. Too soon. For Sam still stood upon his feet, and dropping his own sword, with both hands he held the elven-blade point upwards, fending off that ghastly roof; and so Shelob, with the driving force of her own cruel will, with strength greater than any warrior's hand, thrust herself upon a bitter spike. Deep, deep it pricked, as Sam was crushed slowly to the ground.
No such anguish had Shelob ever known, or dreamed of knowing, in all her long world of wickedness. Not the doughtiest soldier of old Gondor, nor the most savage Orc entrapped, had ever thus endured her, or set blade to her beloved flesh. A shudder went through her. Heaving up again, wrenching away from the pain, she bent her writhing limbs beneath her and sprang backwards in a convulsive leap.
