see nothing beyond it. Mist or shadows blotted out everything like a great blanket all round us. The air seemed hot and heavy; and it was full of rustlings, creakings, and a murmur like voices passing. I think that hundreds more of the Huorns must have been passing by to help in the battle. Later there was a great rumble of thunder away south, and flashes of lightning far away across Rohan. Every now and then we could see mountain-peaks, miles and miles away, stab out suddenly, black and white, and then vanish. And behind us there were noises like thunder in hills, but different. At times the whole valley echoed.
‘It must have been about midnight when the Ents broke the dams and poured all the gathered waters through a gap in the northern wall, down into Isengard. The Huorn-dark had passed, and the thunder had rolled away. The Moon was sinking behind the western mountains.
‘Isengard began to fill up with black creeping streams and pools. They glittered in the last light of the Moon, as they spread over the plain. Every now and then the waters found their way down into some shaft or spouthole. Great white steams hissed up. Smoke rose in billows. There were explosions and gusts of fire. One great coil of vapour went whirling up, twisting round and round Orthanc, until it looked like a tall peak of cloud, fiery underneath and moonlit above. And still more water poured in, until at last Isengard looked like a huge flat saucepan, all steaming and bubbling.’
‘We saw a cloud of smoke and steam from the south last night, when we came to the mouth of Nan Curunír,’ said Aragorn. ‘We feared that Saruman was brewing some new devilry for us.’
‘Not he!’ said Pippin. ‘He was probably choking and not laughing any more. By the morning, yesterday morning, the water had sunk down into all the holes, and there was a dense fog. We took refuge in that guardroom over there; and we had rather a fright. The lake began to overflow and pour out through the old tunnel, and the water was rapidly rising up the steps. We thought we were going to get caught like Orcs in a hole; but we found a winding stair at the back of the store-room that brought us out on top of the arch. It was a squeeze to get out, as the passages had been cracked and half blocked with fallen stone near the top. There we sat high up above the floods and watched the drowning of Isengard. The Ents kept on pouring in more water, till all the fires were quenched and every cave filled. The fogs slowly gathered together and steamed up into a huge umbrella of cloud: it must have been a mile high. In the evening there was a great rainbow over the eastern hills; and then the sunset was blotted out by a thick drizzle on the mountain-sides. It all went very quiet. A few wolves howled mournfully, far away. The Ents stopped the inflow in the night, and sent the Isen back into its old course. And that was the end of it all.
‘Since then the water has been sinking again. There must be outlets somewhere from the caves underneath, I think. If Saruman peeps out of any of his windows, it must look an untidy, dreary mess. We felt very lonely. Not even a visible Ent to talk to in all the ruin; and no news. We spent the night up on top there above the arch, and it was cold and damp and we did not sleep. We had a feeling that anything might happen at any minute. Saruman is still in his tower. There was a noise in the night like a wind coming up the valley. I think the Ents and Huorns that had been away came back then; but where they have all gone to now, I don’t know. It was a misty, moisty morning when we climbed down and looked round again, and nobody was about. And that is about all there is to tell. It seems almost peaceful now after all the turmoil. And safer too, somehow, since Gandalf came back. I could sleep!’
They all fell silent for a while. Gimli re-filled his pipe. ‘There is one thing I wonder about,’ he said as he lit it with his flint and tinder: ‘Wormtongue. You told Théoden he was with Saruman. How did he get there?’
‘Oh
