be a hundred miles away by now, even if he had had to run on his own legs,’ said Pippin.
‘Though Isengard be strong and hard, as cold as stone and bare as bone,
We go, we go, we go to war, to hew the stone and break the door!
     
    There was very much more. A great deal of the song had no words, and was like a music of horns and drums. It was very exciting. But I thought it was only marching music and no more, just a song – until I got here. I know better now.’
    ‘We came down over the last ridge into Nan Curunír, after night had fallen,’ Merry continued. ‘It was then that I first had the feeling that the Forest itself was moving behind us. I thought I was dreaming an entish dream, but Pippin had noticed it too. We were both frightened; but we did not find out more about it until later.
    ‘It was the Huorns, or so the Ents call them in “short language”. Treebeard won’t say much about them, but I think they are Ents that have become almost like trees, at least to look at. They stand here and there in the wood or under its eaves, silent, watching endlessly over the trees; but deep in the darkest dales there are hundreds and hundreds of them, I believe.
    ‘There is a great power in them, and they seem able to wrap themselves in shadow: it is difficult to see them moving. But they do. They can move very quickly, if they are angry. You stand still looking at the weather, maybe, or listening to the rustling of the wind, and then suddenly you find that you are in the middle of a wood with great groping trees all around you. They still have voices, and can speak with the Ents – that is why they are called Huorns, Treebeard says – but they have become queer and wild. Dangerous. I should be terrified of meeting them, if there were no true Ents about to look after them.
    ‘Well, in the early night we crept down a long ravine into the upper end of the Wizard’s Vale, the Ents with all their rustling Huorns behind. We could not see them, of course, but the whole air was full of creaking. It was very dark, a cloudy night. They moved at a great speed as soon as they had left the hills, and made a noise like a rushing wind. The Moon did not appear through the clouds, and not long after midnight there was a tall wood all round the north side of Isengard. There was no sign of enemies nor of any challenge.There was a light gleaming from a high window in the tower, that was all.
    ‘Treebeard and a few more Ents crept on, right round to within sight of the great gates. Pippin and I were with him. We were sitting on Treebeard’s shoulders, and I could feel the quivering tenseness in him. But even when they are roused, Ents can be very cautious and patient. They stood still as carved stones, breathing and listening.
    ‘Then all at once there was a tremendous stir. Trumpets blared, and the walls of Isengard echoed. We thought that we had been discovered, and that battle was going to begin. But nothing of the sort. All Saruman’s people were marching away. I don’t know much about this war, or about the Horsemen of Rohan, but Saruman seems to have meant to finish off the king and all his men with one final blow. He emptied Isengard. I saw the enemy go: endless lines of marching Orcs; and troops of them mounted on great wolves. And there were battalions of Men, too. Many of them carried torches, and in the flare I could see their faces. Most of them were ordinary men, rather tall and dark-haired, and grim but not particularly evil-looking. But there were some others that were horrible: man-high, but with goblin-faces, sallow, leering, squint-eyed. Do you know, they reminded me at once of that Southerner at Bree; only he was not so obviously orc-like as most of these were.’
    ‘I thought of him too,’ said Aragorn. ‘We had many of these half-orcs to deal with at Helm’s Deep. It seems plain now that that Southerner was a spy of Saruman’s; but whether he was working with the Black Riders, or for Saruman alone, I do not know. It is difficult with these evil folk to know when they are in league, and when they are cheating one another.’
    ‘Well, of all sorts together, there must have been ten thousand at the very least,’ said Merry. ‘They took an hour to pass out of the gates. Some went off down the highway to the Fords, and some turned away and went eastward. A bridge has been built down there, about a mile away, where the river runs in a very deep channel. You could see it now, if you stood up. They
