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 Hornburg; three flights of steps led also up on to the wall from the Deep behind; but in front it was smooth, and the great stones of it were set with such skill that no foothold could be found at their joints, and at the top they hung over like a sea-delved cliff.
Gimli stood leaning against the breastwork upon the wall. Legolas sat above on the parapet, fingering his bow, and peering out into the gloom.
‘This is more to my liking,’ said the dwarf, stamping on the stones. ‘Ever my heart rises as we draw near the mountains. There is good rock here. This country has tough bones. I felt them in my feet as we came up from the dike. Give me a year and a hundred of my kin and I would make this a place that armies would break upon like water.’
‘I do not doubt it,’ said Legolas. ‘But you are a dwarf, and dwarves are strange folk. I do not like this place, and I shall like it no more by the light of day. But you comfort me, Gimli, and I am glad to have you standing nigh with your stout legs and your hard axe. I wish there were more of your kin among us. But even more would I give for a hundred good archers of Mirkwood. We shall need them. The Rohirrim have good bowmen after their fashion, but there are too few here, too few.’
‘It is dark for archery,’ said Gimli. ‘Indeed it is time for sleep. Sleep! I feel the need of it, as never I thought any dwarf could. Riding is tiring work. Yet my axe is restless in my hand. Give me a row of orc-necks and room to swing and all weariness will fall from me!’
A slow time passed. Far down in the valley scattered fires still burned. The hosts of Isengard were advancing in silence now. Their torches could be seen winding up the coomb in many lines.
Suddenly from the Dike yells and screams, and the fierce battlecries of men broke out. Flaming brands appeared over the brink and clustered thickly at the breach. Then they scattered and vanished. Men came galloping back over the field and up the ramp to the gate of the Hornburg. The rearguard of the Westfolders had been driven in.
‘The enemy is at hand!’ they said. ‘We loosed every arrow that we had, and filled the Dike with Orcs. But it will not halt them long. Already they are scaling the bank at many points, thick as marching ants. But we have taught them not to carry torches.’
It was now past midnight. The sky was utterly dark, and the stillness of the heavy air foreboded storm. Suddenly the clouds were seared by a blinding flash. Branched lightning smote down upon the eastward hills. For a staring moment the watchers on the walls saw all the space between them and the Dike lit with white light: it was boiling and crawling with black shapes, some squat and broad, some tall and grim, with high helms and sable shields. Hundreds and hundreds more were pouring over the Dike and through the breach. The dark tide flowed up to the walls from cliff to cliff. Thunder rolled in the valley. Rain came lashing down.
Arrows thick as the rain came whistling over the battlements, and fell clinking and glancing on the stones. Some found a mark. The assault on Helm’s Deep had begun, but no sound or challenge was heard within; no answering arrows came.
The assailing hosts halted, foiled by the silent menace of rock and wall. Ever and again the lightning tore aside the darkness. Then the Orcs screamed, waving spear and sword, and shooting a cloud of arrows at any that stood revealed upon the battlements; and the men of the Mark amazed looked out, as it seemed to them, upon a great field of dark corn, tossed by a tempest of war, and every ear glinted with barbed light.
Brazen trumpets sounded. The enemy surged forward, some against the Deeping Wall, others towards the causeway and the ramp that led up to the Hornburg-gates. There the
