‘Not yet!’ said Gandalf. ‘But there is no time for wonder. Off you go, all of you, down the stairs! Wait a few minutes for me at the bottom, but if I do not come soon, go on! Go quickly and choose paths leading right and downwards.’
‘We cannot leave you to hold the door alone!’ said Aragorn.
‘Do as I say!’ said Gandalf fiercely. ‘Swords are no more use here. Go!’
The passage was lit by no shaft and was utterly dark. They groped their way down a long flight of steps, and then looked back; but they could see nothing, except high above them the faint glimmer of the wizard’s staff. He seemed to be still standing on guard by the closed door. Frodo breathed heavily and leaned against Sam, who put his arms about him. They stood peering up the stairs into the darkness. Frodo thought he could hear the voice of Gandalf above, muttering words that ran down the sloping roof with a sighing echo. He could not catch what was said. The walls seemed to be trembling. Every now and again the drum-beats throbbed and rolled: doom, doom.
Suddenly at the top of the stair there was a stab of white light. Then there was a dull rumble and a heavy thud. The drum-beats broke out wildly: doom-boom, doom-boom, and then stopped. Gandalf came flying down the steps and fell to the ground in the midst of the Company.
‘Well, well! That’s over!’ said the wizard struggling to his feet. ‘I have done all that I could. But I have met my match, and have nearly been destroyed. But don’t stand here! Go on! You will have to do without light for a while: I am rather shaken. Go on! Go on! Where are you, Gimli? Come ahead with me! Keep close behind, all of you!’
They stumbled after him wondering what had happened. Doom, doom went the drum-beats again: they now sounded muffled and far away, but they were following. There was no other sound of pursuit, neither tramp of feet, nor any voice. Gandalf took no turns, right or left, for the passage seemed to be going in the direction that he desired. Every now and again it descended a flight of steps, fifty or more, to a lower level. At the moment that was their chief danger; for in the dark they could not see a descent, until they came on it and put their feet out into emptiness. Gandalf felt the ground with his staff like a blind man.
At the end of an hour they had gone a mile, or maybe a little more, and had descended many flights of stairs. There was still no sound of pursuit. Almost they began to hope that they would escape. At the bottom of the seventh flight Gandalf halted.
‘It is getting hot!’ he gasped. ‘We ought to be down at least to the level of the Gates now. Soon I think we should look for a left-hand turn to take us east. I hope it is not far. I am very weary. I must rest here a moment, even if all the orcs ever spawned are after us.’
Gimli took his arm and helped him down to a seat on the step. ‘What happened away up there at the door?’ he asked. ‘Did you meet the beater of the drums?’
‘I do not know,’ answered Gandalf. ‘But I found myself suddenly faced by something that I have not met before. I could think of nothing to do but to try and put a shutting-spell on the door. I know many; but to do things of that kind rightly requires time, and even then the door can be broken by strength.
‘As I stood there I could hear orc-voices on the other side: at any moment I thought they would burst it open. I could not hear what was said; they seemed to be talking in their own hideous language. All I caught was ghâsh: that is “fire”. Then something came into the chamber – I felt it through the door, and the orcs themselves were afraid and fell silent. It laid hold of the iron ring, and then it perceived me and my spell.
‘What it was I cannot guess, but I have never felt such a challenge. The counter-spell was terrible. It nearly broke me. For an instant the door left my control and began to open! I had to speak a word of Command. That proved too great a strain. The door burst in pieces. Something dark as a cloud was blocking out all the light inside, and I was thrown backwards down the stairs. All the wall gave way, and the roof of the chamber as well, I think.
‘I am afraid Balin is buried deep, and maybe something else is buried there too. I cannot say. But at least the passage behind us was completely blocked. Ah! I have never felt so spent, but it is passing. And now what about you, Frodo? There was not time to say so, but I have never been more delighted in my life than when you spoke. I feared that it was a brave but dead hobbit that Aragorn was carrying.’
‘What about me?’ said Frodo. ‘I am alive, and whole I think. I am bruised and in pain, but it is not too bad.’
‘Well,’ said Aragorn, ‘I can only say that hobbits are made of a stuff so tough that I have never met the like of it. Had I known, I would have spoken softer in the Inn at Bree! That spear-thrust would have skewered a wild boar!’
