and I quote:
'"Hinder me? Thou fool.
No living man may hinder me!"
Then
Merry heard of all sounds in that hour the strangest. It seemed that
Dernhelm laughed, and the clear voice was like
the ring of steel.
"
But no living man am I! You look upon a woman.
Eowyn am I, Eomund's daughter. You stand between me and my lord and kin. Begone, if you be not deathless! For living or dark undead, I will smite you if you touch him."...
'...Eowyn it was, and Dernhelm also. For into Merry's mind flashed the memory of the face he saw at the riding from Dunharrow: the face of one that goes seeking death, having no hope. Pity filled his heart and great wonder, and suddenly the slow-kindled courage of his
race awoke. He clenched his hand. She should not die, so fair, so desperate. At least she should not die alone, unaided...
'...Out of the wreck rose the
Black Rider, tall and threatening, towering above her. With a cry of hatred that stung the very ears like venom, he let fall his mace. Her sheild was shivered into many peices, and her arm was broken; she stumbled to her knees. He bent over her like a cloud, and his eyes glittered; he raised his mace to kill.
But suddenly he too stumbled forward with a cry of bitter pain, and his stroke went wide, driving into the ground. Merry's sword had stabbed him from behind, shearing through his black mantle, and peirced the sinew behind his mighty knee.
"Eowyn, Eowyn!" cried Merry. Then tottering, struggling up, with her last strength
she drove her sword between crown and mantle, as the great shoulders bowed before her. The sword broke sparkling into many shards. The crown rolled away with a clang. Eowyn fell forward onto her falled foe. But lo! the mantle and hauberk were empty. Shapeless they lay now on the ground, torn and tumbled; and a cry went up into the shuddering air, and faded into a shrill wailing, passing with the wind, a voice bodiless and thin that died, and was swallowed up, and was never heard again in that age of this world.'
Meanwhile,
Frodo and
Sam are in
Shelob's lair, so how could Frodo have killed the
Witch King? And Merry, not being a man, can wound him, but it is Eowyn, not the
hobbits that causes him to actually
die. It says so, right there!
