“All about the hills the hosts of Mordor raged. The Captains of the West were foundering in a gathering sea. The sun gleamed red, and under the wings of the Nazgul the shadows of death fell dark upon the earth. Aragorn stood beneath his banner, silent and stern, as one lost in thought of things long past or far away; but his eyes gleamed like stars that shine the brighter as the night deepens. Upon the hill-top stood Gandalf, and he was white and cold and no shadow fell on him. The onslaught of Mordor broke like a wave on the beleaguered hills, voices roaring like a tide amid the wreck and crash of arms.
As if to his eyes some sudden vision had been given, Gandalf stirred; and he turned, looking back north where the skies were pale and clear. Then he lifted up his hands and cried in a loud voice ringing above the din: The Eagles are coming! And many voices answered crying: The Eagles are coming! The Eagles are coming! The hosts of Mordor looked up and wondered what this sign might mean.
There came Gwaihir the Windlord, and Landroval his brother, greatest of all the Eagles of the North, mightiest of the descendants of old Thorondor, who built his eyries in the inaccessible peaks of the Encircling Mountains when Middle-earth was young. Behind them in long swift lines came all their vassals from the northern mountains, speeding on a gathering wind. Straight down upon the Nazgul they bore, stooping suddenly out of the high airs, and the rush of their wide wings as they passed over was like a gale.
But the Nazgul turned and fled, and vanished into Mordor's shadows, hearing a sudden terrible call out of the Dark Tower; and even at that moment all the hosts of Mordor trembled, doubt clutched their hearts, their laughter failed, their hands shook and their limbs were loosed. The Power that drove them on and filled them with hate and fury was wavering, its will was removed from them; and now looking in the eyes of their enemies they saw a deadly light and were afraid.
Then all the Captains of the West cried aloud, for their hearts were filled with a new hope in the midst of darkness. Out from the beleaguered hills knights of Gondor, Riders of Rohan, Dunedain of the North, close-serried companies, drove against their wavering foes, piercing the press with the thrust of bitter spears. But Gandalf lifted up his arms and called once more in a clear voice:
'Stand, Men of the West! Stand and wait! This is the hour of doom.'
And even as he spoke the earth rocked beneath their feet. Then rising swiftly up, far above the Towers of the Black Gate, high above the mountains, a vast soaring darkness sprang into the sky, flickering with fire. The earth groaned and quaked. The Towers of the Teeth swayed, tottered, and fell down; the mighty rampart crumbled; the Black Gate was hurled in ruin; and from far away, now dim, now growing, now mounting to the clouds, there came a drumming rumble, a roar, a long echoing roll of ruinous noise.
'The realm of Sauron is ended!' said Gandalf. 'The Ring-bearer has fulfilled his Quest.' And as the Captains gazed south to the Land of Mordor, it seemed to them that, black against the pall of cloud, there rose a huge shape of shadow, impenetrable, lightning-crowned, filling all the sky. Enormous it reared above the world, and stretched out towards them a vast threatening hand, terrible but impotent: for even as it leaned over them, a great wind took it, and it was all blown away, and passed; and then a hush fell.
The Captains bowed their heads...”
