Bridge of Khazad-dûm

The Bridge of Khazad-dûm is the narrow, curving stone span without kerb or rail that crosses a black chasm in the Second Hall of Old Moria, serving as the ancient Dwarves' final defence before the outer door. It is here that the Company's desperate flight from the pursuing Orcs and the Balrog reaches its crisis, and here that Gandalf makes his last stand, an act that simultaneously saves his companions and removes him from the Quest.

Location and Description

The bridge is a slender arch of stone, fifty feet long, that leaps across a chasm of unknown depth at the eastern end of the Second Hall. It has no parapet or railing, and can only be crossed in single file. Beyond it lies a broad stair leading up to the outer door and the Dimrill Gate. The bridge is an ancient defensive work of the Dwarves, designed to prevent any enemy that might capture the First Hall from reaching the outer passages. When the Company reaches it, the hall behind them is filled with Orcs and the Balrog is approaching; arrows fall among them, and one strikes Frodo but is turned by his mithril coat.

The Confrontation

Gandalf orders the others to flee across the bridge, declaring that the Balrog is a foe beyond any of them and that he must hold the narrow way. Aragorn and Boromir initially refuse to leave him, but Gandalf insists. The Balrog reaches the bridge, and Gandalf stands in the middle of the span, leaning on his staff in his left hand, with Glamdring gleaming cold and white in his right. The Balrog halts, and the shadow about it reaches out like two vast wings. It raises its whip, the thongs whine and crack, and fire comes from its nostrils. Gandalf declares: 'You cannot pass. I am a servant of the Secret Fire, wielder of the flame of Anor. You cannot pass. The dark fire will not avail you, flame of Udûn. Go back to the Shadow! You cannot pass.' The Balrog makes no answer; its fire seems to die, but the darkness grows. It steps forward, draws itself up to a great height, and spreads its wings from wall to wall. A red sword leaps flaming from the shadow, and Glamdring glitters white in answer. There is a ringing clash and a stab of white fire; the Balrog falls back, and its sword flies up in molten fragments. Gandalf sways on the bridge, steps back a pace, and then stands still again, repeating 'You cannot pass!' With a bound the Balrog leaps full upon the bridge, its whip whirling and hissing.

The Fall

Aragorn and Boromir run back to aid Gandalf, but at that moment Gandalf lifts his staff and smites the bridge before him, crying aloud. The staff breaks asunder and falls from his hand. A blinding sheet of white flame springs up, and the bridge cracks. Right at the Balrog's feet it breaks, and the stone upon which it stood crashes into the gulf, while the rest remains poised, quivering like a tongue of rock thrust out into emptiness. With a terrible cry the Balrog falls forward, and its shadow plunges down and vanishes. But even as it falls, it swings its whip, and the thongs lash and curl about the wizard's knees, dragging him to the brink. He staggers and falls, grasps vainly at the stone, and slides into the abyss, crying 'Fly, you fools!' before he is gone. The fires go out, and blank darkness falls. The rest of the bridge cracks and falls. Aragorn leads the Company away, weeping, as the drum-beats roll mournfully behind them: doom, doom, doom.

Consequences

The fall of Gandalf at the Bridge of Khazad-dûm is the single most devastating blow to the Fellowship. It removes their guide, their chief source of wisdom and power, and the one figure who could most effectively counter the threats ahead. The Company is left leaderless and must rely on Aragorn, who is himself uncertain of the path. The event also deepens the sense of loss and despair that shadows the rest of the journey. Gandalf's fall is not, however, the end of his story; he returns later as Gandalf the White, having passed through fire and deep water and defeated the Balrog on the peak of Celebdil. The bridge itself is destroyed in the confrontation, sealing the way behind the Company and ensuring that no pursuit can follow from that direction.
