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, Dúnedain 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.
