‘That Gandalf Greyhame has need of haste,’ answered Háma. ‘Ever he goes and comes unlooked-for.’
‘Wormtongue, were he here, would not find it hard to explain,’ said the other.
‘True enough,’ said Háma; ‘but for myself, I will wait until I see Gandalf again.’
‘Maybe you will wait long,’ said the other.
The host turned away now from the road to the Fords of Isen and bent their course southward. Night fell, and still they rode on. The hills drew near, but the tall peaks of Thrihyrne were already dim against the darkening sky. Still some miles away, on the far side of the Westfold Vale, a great bay in the mountains, lay a green coomb, out of which a gorge opened in the hills. Men of that land called it Helm’s Deep, after a hero of old wars who had made his refuge there. Ever steeper and narrower it wound inward from the north under the shadow of the Thrihyrne, till the crowhaunted cliffs rose like mighty towers on either side, shutting out the light.
At Helm’s Gate, before the mouth of the Deep, there was a heel of rock thrust outward by the northern cliff. There upon its spur stood high walls of ancient stone, and within them was a lofty tower. Men said that in the far-off days of the glory of Gondor the sea-kings had built here this fastness with the hands of giants. The Hornburg it was called, for a trumpet sounded upon the tower echoed in the Deep behind, as if armies long-forgotten were issuing to war from caves beneath the hills. A wall, too, the men of old had made from the Hornburg to the southern cliff, barring the entrance to the gorge. Beneath it by a wide culvert the Deeping-stream passed out. About the feet of the Hornrock it wound, and flowed then in a gully through the midst of a wide green gore, sloping gently down from Helm’s Gate to Helm’s Dike. Thence it fell into the Deeping-coomb and out into the Westfold Vale. There in the Hornburg at Helm’s Gate Erkenbrand, master of Westfold on the borders of the Mark, now dwelt. As the days darkened with threat of war, being wise, he had repaired the wall and made the fastness strong.
The Riders were still in the low valley before the mouth of the Coomb, when cries and hornblasts were heard from their scouts that went in front. Out of the darkness arrows whistled. Swiftly a scout rode back and reported that wolf-riders were abroad in the valley, and that a host of Orcs and wild men were hurrying southward from the Fords of Isen and seemed to be making for Helm’s Deep.
‘We have found many of our folk lying slain as they fled thither,’ said the scout. ‘And we have met scattered companies, going this way and that, leaderless. What has become of Erkenbrand none seem to know. It is likely that he will be overtaken ere he can reach Helm’s Gate, if he has not already perished.’
‘Has aught been seen of Gandalf?’ asked Théoden.
‘Yes, lord. Many have seen an old man in white upon a horse, passing hither and thither over the plains like wind in the grass. Some thought he was Saruman. It is said that he went away ere nightfall towards Isengard. Some say also that Wormtongue was seen earlier, going northward with a company of Orcs.’
‘It will go ill with Wormtongue, if Gandalf comes upon him,’ said Théoden. ‘Nonetheless I miss now both my counsellors, the old and the new. But in this need we have no better choice than to go on, as Gandalf said, to Helm’s Gate, whether Erkenbrand be there or no. Is it known how great is the host that comes from the North?’
‘It is very great,’ said the scout. ‘He that flies counts every foeman twice, yet I have spoken to stouthearted men, and I do not doubt that the main strength of the enemy is many times as great as all that we have here.’
‘Then let us be swift,’ said éomer. ‘Let us drive through such foes as are already between us and the fastness. There are caves in Helm’s Deep where hundreds may lie hid; and secret ways lead thence up on to the hills.’
‘Trust not to secret ways,’ said the king. ‘Saruman has long spied out this land. Still in that place our defence may last long. Let us go!’
Aragorn and Legolas went now with éomer in the van. On through the dark night they rode, ever slower as the darkness deepened and their way climbed southward, higher and higher into the dim folds about the mountains’ feet. They found few of the enemy before them. Here and there they came upon roving bands of Orcs; but they fled ere the Riders could take or slay them.
‘It will not be long I fear,’ said éomer, ‘ere the coming of the king’s host will be known to the leader of our enemies, Saruman or whatever captain he has sent forth.’
The rumour of war grew behind them. Now they could hear, borne over the dark, the sound of harsh singing. They had climbed far up into the Deeping-coomb when they looked back. Then they saw torches, countless points of fiery light upon the black fields behind, scattered like red flowers, or winding up from the lowlands in long flickering lines. Here and there a larger blaze leapt up.
‘It is a great host and follows us hard,’ said Aragorn.
‘They bring fire,’ said Théoden, ‘and they are burning as they come, rick, cot, and tree. This was a rich vale and had many homesteads. Alas for my folk!’
‘Would that day was here and we might ride down upon them like a storm out of the mountains!’ said Aragorn. ‘It grieves me to fly before them.’
‘We need not fly much further,’ said éomer. ‘Not far ahead now lies Helm’s Dike, an ancient trench and rampart scored across the coomb, two furlongs below Helm’s Gate. There we can turn and give battle.’
‘Nay, we are too few to defend the Dike,’ said Théoden. ‘It is a mile long or more, and the breach in it is wide.’
‘At the breach our rearguard must stand, if we are pressed,’ said éomer.
There was neither star nor moon when the Riders came to the breach in the Dike, where the stream from above passed out, and the road beside it ran down from the Hornburg. The rampart loomed suddenly before them, a high shadow beyond a dark pit. As they rode up a sentinel challenged them.
‘The Lord of the Mark rides to Helm’s Gate,’ éomer answered. ‘I, éomer son of éomund, speak.’
‘This is good tidings beyond hope,’ said the sentinel. ‘Hasten! The enemy is on your heels.’
The host passed through the breach and halted on the sloping sward above. They now learned to their joy that Erkenbrand had left many men to hold Helm’s Gate, and more had since escaped thither.
‘Maybe, we have a thousand fit to fight on foot,’ said Gamling, an old man, the leader of those that watched the Dike. ‘But most of them have seen too many winters, as I have, or too few, as my son’s son here. What news of Erkenbrand? Word came yesterday that he was retreating hither with all that is left of the best Riders of Westfold. But he has not come.’
‘I fear that he will not come now,’ said éomer. ‘Our scouts have gained no news of him, and the enemy fills all the valley behind us.’
‘I would that he had escaped,’ said Théoden. ‘He was a mighty man. In him lived again the valour of Helm the Hammerhand. But we cannot await him here. We must draw all our forces now behind the walls. Are you well stored? We bring little provision, for we rode forth to open battle, not to a siege.’
‘Behind us in the caves of the Deep are three parts of the folk of Westfold, old and young, children and women,’ said Gamling. ‘But great store of food, and many beasts and their fodder, have also been gathered there.’
‘That is well,’ said éomer. ‘They are burning or despoiling all that is left in the vale.’
‘If they come to bargain for our goods at Helm’s Gate, they will pay a high price,’ said Gamling.
The king and his Riders passed on. Before the causeway that crossed the stream they dismounted. In a long file they led their horses up the ramp and passed within the gates of the Hornburg. There they were welcomed again with joy and renewed hope; for now there were men enough to man both the burg and the barrier wall.
Quickly éomer set his men in readiness. The king and the men of his household were in the Hornburg, and there also were many of the Westfold-men. But on the Deeping Wall and its tower, and behind it, éomer arrayed most of the strength that he had, for here the defence seemed more doubtful, if the assault were determined and in great force. The horses were led far up the Deep under such guard as could be spared.
The Deeping Wall was twenty feet high, and so thick that four men could walk abreast along the top, sheltered by a parapet over which only a tall man could look. Here and there were clefts in the stone through which men could shoot. This battlement could be reached by a stair running down from a door in the outer court of the
