‘But, though I could not see what was happening in the dark, I believe that Huorns began to move south, as soon as the gates were shut again. Their business was with Orcs I think. They were far down the valley in the morning; or at any rate there was a shadow there that one couldn’t see through.
‘As soon as Saruman had sent off all his army, our turn came. Treebeard put us down, and went up to the gates, and began hammering on the doors, and calling for Saruman. There was no answer, except arrows and stones from the walls. But arrows are no use against Ents. They hurt them, of course, and infuriate them: like stinging flies. But an Ent can be stuck as full of orc-arrows as a pin-cushion, and take no serious harm. They cannot be poisoned, for one thing; and their skin seems to be very thick, and tougher than bark. It takes a very heavy axe-stroke to wound them seriously. They don’t like axes. But there would have to be a great many axe-men to one Ent: a man that hacks once at an Ent never gets a chance of a second blow. A punch from an Ent-fist crumples up iron like thin tin.
‘When Treebeard had got a few arrows in him, he began to warm up, to get positively ‘‘hasty’’, as he would say. He let out a great hoom-hom, and a dozen more Ents came striding up. An angry Ent is terrifying. Their fingers, and their toes, just freeze on to rock; and they tear it up like bread-crust. It was like watching the work of great tree-roots in a hundred years, all packed into a few moments.
‘They pushed, pulled, tore, shook, and hammered; and clang-bang, crash-crack, in five minutes they had these huge gates just lying in ruin; and some were already beginning to eat into the walls, like rabbits in a sand-pit. I don’t know what Saruman thought was happening; but anyway he did not know how to deal with it. His wizardry may have been falling off lately, of course; but anyway I think he has not much grit, not much plain courage alone in a tight place without a lot of slaves and machines and things, if you know what I mean. Very different from old Gandalf. I wonder if his fame was not all along mainly due to his cleverness in settling at Isengard.’
‘No,’ said Aragorn. ‘Once he was as great as his fame made him. His knowledge was deep, his thought was subtle, and his hands marvellously skilled; and he had a power over the minds of others. The wise he could persuade, and the smaller folk he could daunt. That power he certainly still keeps. There are not many in Middle-earth that I should say were safe, if they were left alone to talk with him, even now when he has suffered a defeat. Gandalf, Elrond, and Galadriel, perhaps, now that his wickedness has been laid bare, but very few others.’
‘The Ents are safe,’ said Pippin. ‘He seems at one time to have got round them, but never again. And anyway he did not understand them; and he made the great mistake of leaving them out of his calculations. He had no plan for them, and there was no time to make any, once they had set to work. As soon as our attack began, the few remaining rats in Isengard started bolting through every hole that the Ents made. The Ents let the Men go, after they had questioned them, two or three dozen only down at this end. I don’t think many orc-folk, of any size, escaped. Not from the Huorns: there was a wood full of them all round Isengard by that time, as well as those that had gone down the valley.
‘When the Ents had reduced a large part of the southern walls to rubbish, and what was left of his people had bolted and deserted him, Saruman fled in a panic. He seems to have been at the gates when we arrived: I expect he came to watch his splendid army march out. When the Ents broke their way in, he left in a hurry. They did not spot him at first. But the night had opened out, and there was a great light of stars, quite enough for Ents to see by, and suddenly Quickbeam gave a cry ‘‘The tree-killer, the tree-killer!’’ Quickbeam is a gentle creature, but he hates Saruman all the more fiercely for that: his people suffered cruelly from orc-axes. He leapt down the path from the inner gate, and he can move like a wind when he is roused. There was a pale figure hurrying away in and out of the shadows of the pillars, and it had nearly reached the stairs to the tower-door. But it was a near thing. Quickbeam was so hot after him, that he was within a step or two of being caught and strangled when he slipped in through the door.
‘When Saruman was safe back in Orthanc, it was not long before he set some of his precious machinery to work. By that time there were many Ents inside Isengard: some had followed Quickbeam, and others had burst in from the north and east; they were roaming about and doing a great deal of damage. Suddenly up came fires and foul fumes: the vents and shafts all over the plain began to spout and belch. Several of the Ents got scorched and blistered. One of them, Beechbone I think he was called, a very tall handsome Ent, got caught in a spray of some liquid fire and burned like a torch: a horrible sight.
‘That sent them mad. I thought that they had been really roused before; but I was wrong. I saw what it was like at last. It was staggering. They roared and boomed and trumpeted, until stones began to crack and fall at the mere noise of them. Merry and I lay on the ground and stuffed our cloaks into our ears. Round and round the rock of Orthanc the Ents went striding and storming like a howling gale, breaking pillars, hurling avalanches of boulders down the shafts, tossing up huge slabs of stone into the air like leaves. The tower was in the middle of a spinning whirlwind. I saw iron posts and blocks of masonry go rocketing up hundreds of feet, and smash against the windows of Orthanc. But Treebeard kept his head. He had not had any burns, luckily. He did not want his folk to hurt themselves in their fury, and he did not want Saruman to escape out of some hole in the confusion. Many of the Ents were hurling themselves against the Orthanc-rock; but that defeated them. It is very smooth and hard. Some wizardry is in it, perhaps, older and stronger than Saruman’s. Anyway they could not get a grip on it, or make a crack in it; and they were bruising and wounding themselves against it.
‘So Treebeard went out into the ring and shouted. His enormous voice rose above all the din. There was a dead silence, suddenly. In it we heard a shrill laugh from a high window in the tower. That had a queer effect on the Ents. They had been boiling over; now they became cold, grim as ice, and quiet. They left the plain and gathered round Treebeard, standing quite still. He spoke to them for a little in their own language; I think he was telling them of a plan he had made in his old head long before. Then they just faded silently away in the grey light. Day was dawning by that time.
‘They set a watch on the tower, I believe, but the watchers were so well hidden in shadows and kept so still, that I could not see them. The others went away north. All that day they were busy, out of sight. Most of the time we were left alone. It was a dreary day; and we wandered about a bit, though we kept out of the view of the windows of Orthanc, as much as we could: they stared at us so threateningly. A good deal of the time we spent looking for something to eat. And also we sat and talked, wondering what was happening away south in Rohan, and what had become of all the rest of our Company. Every now and then we could hear in the distance the rattle and fall of stone, and thudding noises echoing in the hills.
