Even as they spoke there came a blare of trumpets. Then there was a crash and a flash of flame and smoke. The waters of the Deeping-stream poured out hissing and foaming: they were choked no longer, a gaping hole was blasted in the wall. A host of dark shapes poured in.
‘Devilry of Saruman!’ cried Aragorn. ‘They have crept in the culvert again, while we talked, and they have lit the fire of Orthanc beneath our feet. Elendil, Elendil!’ he shouted, as he leaped down into the breach; but even as he did so a hundred ladders were raised against the battlements. Over the wall and under the wall the last assault came sweeping like a dark wave upon a hill of sand. The defence was swept away. Some of the Riders were driven back, further and further into the Deep, falling and fighting as they gave way, step by step, towards the caves. Others cut their way back towards the citadel.
A broad stairway climbed from the Deep up to the Rock and the rear-gate of the Hornburg. Near the bottom stood Aragorn. In his hand still Andúril gleamed, and the terror of the sword for a while held back the enemy, as one by one all who could gain the stair passed up towards the gate. Behind on the upper steps knelt Legolas. His bow was bent, but one gleaned arrow was all that he had left, and he peered out now, ready to shoot the first Orc that should dare to approach the stair.
‘All who can have now got safe within, Aragorn,’ he called. ‘Come back!’
Aragorn turned and sped up the stair; but as he ran he stumbled in his weariness. At once his enemies leapt forward. Up came the Orcs, yelling, with their long arms stretched out to seize him. The foremost fell with Legolas’ last arrow in his throat, but the rest sprang over him. Then a great boulder, cast from the outer wall above, crashed down upon the stair, and hurled them back into the Deep. Aragorn gained the door, and swiftly it clanged to behind him.
‘Things go ill, my friends,’ he said, wiping the sweat from his brow with his arm.
‘Ill enough,’ said Legolas, ‘but not yet hopeless, while we have you with us. Where is Gimli?’
‘I do not know,’ said Aragorn. ‘I last saw him fighting on the ground behind the wall, but the enemy swept us apart.’
‘Alas! That is evil news,’ said Legolas.
‘He is stout and strong,’ said Aragorn. ‘Let us hope that he will escape back to the caves. There he would be safe for a while. Safer than we. Such a refuge would be to the liking of a dwarf.’
‘That must be my hope,’ said Legolas. ‘But I wish that he had come this way. I desired to tell Master Gimli that my tale is now thirty-nine.’
‘If he wins back to the caves, he will pass your count again,’ laughed Aragorn. ‘Never did I see an axe so wielded.’
‘I must go and seek some arrows,’ said Legolas. ‘Would that this night would end, and I could have better light for shooting.’
Aragorn now passed into the citadel. There to his dismay he learned that Éomer had not reached the Hornburg.
‘Nay, he did not come to the Rock,’ said one of the Westfold-men. ‘I last saw him gathering men about him and fighting in the mouth of the Deep. Gamling was with him, and the dwarf; but I could not come to them.’
Aragorn strode on through the inner court, and mounted to a high chamber in the tower. There stood the king, dark against a narrow window, looking out upon the vale.
‘What is the news, Aragorn?’ he said.
‘The Deeping Wall is taken, lord, and all the defence swept away; but many have escaped hither to the Rock.’
‘Is Éomer here?’
‘No, lord. But many of your men retreated into the Deep; and some say that Éomer was amongst them. In the narrows they may hold back the enemy and come within the caves. What hope they may have then I do not know.’
‘More than we. Good provision, it is said. And the air is wholesome there because of the outlets through fissures in the rock far above. None can force an entrance against determined men. They may hold out long.’
‘But the Orcs have brought a devilry from Orthanc,’ said Aragorn. ‘They have a blasting fire, and with it they took the Wall. If they cannot come in the caves, they may seal up those that are inside. But now we must turn all our thought to our own defence.’
‘I fret in this prison,’ said Théoden. ‘If I could have set a spear in rest, riding before my men upon the field, maybe I could have felt again the joy of battle, and so ended. But I serve little purpose here.’
‘Here at least you are guarded in the strongest fastness of the Mark,’ said Aragorn. ‘More hope we have to defend you in the Hornburg than in Edoras, or even at Dunharrow in the mountains.’
