With a furious oath Thespides wheeled and galloped back down the valley where his knights waited impatiently.
Amalric shook his head. `You should not have let him return, Conan. I – look there!’
Conan sprang up with a curse. Thespides had swept in beside his men. They could hear his impassioned voice faintly, but his gesture toward the approaching horde was significant enough. In another instant five hundred lances dipped and the steel-clad company was thundering down the valley.
A young page came running from Yasmela’s pavilion, crying to Conan in a shrill, eager voice. `My Lord, the princess asks why you do not follow and support Count Thespides?’
`Because I am not so great a fool as he,’ grunted Conan, reseating himself on the boulder and beginning to gnaw a huge beef-bone.
`You grow sober with authority,’ quoth Amalric. `Such madness as that was always your particular joy.’
`Aye, when I had only my own life to consider,’ answered Conan. `Now – what in hell-‘
The horde had halted. From the extreme wing rushed a chariot, the naked charioteer lashing the steeds like a madman; the other occupant was a tall figure whose robe floated spectrally on the wind. He held in his arms a great vessel of gold and from it poured a thin stream that sparkled in the sunlight. Across the whole front of the desert horde the chariot swept, and behind its thundering wheels was left, like the wake behind a ship, a long thin powdery line that glittered in the sands like the phosphorescent track of a serpent.
`That’s Natohk!’ swore Amalric. `What hellish seed is he sowing?’
The charging knights had not checked their headlong pace. Another fifty paces and they would crash into the uneven Kushite ranks, which stood motionless, spears lifted. Now the foremost knights had reached the thin line that glittered across the sands. They did not heed that crawling menace. But as the steel-shod hoofs of the horses struck it, it was as when steel strikes flint – but with more terrible result. A terrific explosion rocked the desert, which seemed to split apart along the strewn line with an awful burst of white flame.
In that instant the whole foremost line of the knights was seen enveloped in that flame, horses and steel-clad riders withering in the glare like insects in an open blaze. The next instant the rear ranks were piling up on their charred bodies. Unable to check their headlong velocity, rank after rank crashed into the ruins. With appalling suddenness the charge had turned into a shambles where armored figures died amid screaming, mangled horses.
Now the illusion of confusion vanished as the horde settled into orderly lines. The wild Kushites rushed into the shambles, spearing the wounded, bursting the helmets of the knights with stones and iron hammers. It was all over so quickly that the watchers on the slopes stood dazed; and again the horde moved forward, splitting to avoid the charred waste of corpses. From the hills went up a cry: `We fight not men but devils!’
On either ridge the hillmen wavered. One rushed toward the plateau, froth dripping from his beard.
`Flee, flee!’ he slobbered. `Who can fight Natohk’s magic?’
With a snarl Conan bounded from his boulder and smote him with the beef-bone; he dropped, blood starting from nose and mouth. Conan drew his sword, his eyes slits of blue bale-fire.
`Back to your posts!’ he yelled. `Let another take a backward step and I’ll shear off his head! Fight, damn you!’
The rout halted as quickly as it had begun. Conan’s fierce personality was like a dash of ice-water in their whirling blaze of terror.
`Take your places,’ he directed quickly. `And stand to it! Neither man nor devil comes up Shamla Pass this day!’
Where the plateau rim broke to the valley slope the mercenaries braced their belts and gripped their spears. Behind them the lancers sat their steeds, and to one side were stationed the Khoraja spearmen as reserves. To Yasmela, standing white and speechless at the door of her tent, the host seemed a pitiful handful in comparison to the thronging desert horde.
Conan stood among the spearmen. He knew the invaders would not try to drive a chariot charge up the Pass in the teeth of the archers, but he grunted with surprize to see the riders dismounting. These wild men had no supply trains. Canteens and pouches hung at their saddle-peaks. Now they drank the last of their water and threw the canteens away.
`This is the death-grip,’ he muttered as the lines formed on foot. `I’d rather have had a cavalry charge; wounded horses bolt and ruin formations.’
The horde had formed into a huge wedge, of which the tip was the Stygians and the body, the mailed asshuri, flanked by the nomads. In close formation, shields lifted, they rolled onward, while behind them a tall figure in a motionless chariot lifted wide-robed arms in grisly invocation.
As the horde entered the wide valley mouth the hillmen loosed their shafts. In spite of the protective formation, men dropped by dozens. The Stygians had discarded their bows; helmeted heads bent to the blast, dark eyes glaring over the rims of their shields, they came on in an inexorable surge, striding over their fallen comrades. But the Shemites gave back the fire, and the clouds of arrows darkened the skies. Conan gazed over the billowing waves of spears and wondered what new horror the sorcerer would invoke. Somehow he felt that Natohk, like all his kind, was more terrible in defense than in attack; to take the offensive against him invited disaster.
But surely it was magic that drove the horde on in the teeth of death. Conan caught his breath at the havoc wrought in the onsweeping ranks. The edges of the wedge seemed to be melting away, and already the valley was strewn with dead men. Yet the survivors came on like madmen unaware of death. By the very numbers of their bows, they began to swamp the archers on the cliffs. Clouds of shafts sped upward, driving the hillmen to cover. Panic struck at their hearts at that unwavering advance, and they plied their bows madly, eyes glaring like trapped wolves.
As the horde neared the narrower neck of the Pass, boulders thundered down, crushing men by the scores, but the charge did not waver. Conan’s wolves braced themselves for the inevitable concussion. In their close formation and superior armor, they took little hurt from the arrows. It was the impact of the charge Conan feared, when the huge wedge should crash against his thin ranks. And he realized now there was no breaking of that onslaught. He gripped the shoulder of a Zaheemi who stood near.
`Is there any way by which mounted men can get down into the blind valley beyond that western ridge?’
`Aye, a steep, perilous path, secret and eternally guarded. But-‘
Conan was dragging him along to where Amalric sat his great war-horse.
`Amalric!’ he snapped. `Follow this man! He’ll lead you into yon outer valley. Ride down it, circle the end of the ridge, and strike the horde from the rear. Speak not, but go! I know it’s madness, but we’re doomed anyway; we’ll do all the damage we can before we die! Haste!’
Amalric’s mustache bristled in a fierce grin, and a few moments later his lancers were following the guide into a tangle of gorges leading off from the plateau. Conan ran back to the pikemen, sword in hand.
He was not too soon. On either ridge Shupras’s hillmen, mad with anticipation of defeat, rained down their shafts desperately. Men died like flies in the valley and along the slopes – and with a roar and an irresistible upward surge the Stygians crashed against the mercenaries.
In a hurricane of thundering steel, the lines twisted and swayed. It was war-bred noble against professional soldier.
Shields crashed against shields, and between them spears drove in and blood spurted.
Conan saw the mighty form of prince Kutamun across the sea of swords, but the press held him hard, breast to breast with dark shapes that gasped and slashed. Behind the Stygians the asshuri were surging and yelling.
On either hand the nomads climbed the cliffs and came to hand-grips with their mountain kin. All along the crests of the ridges the combat raged in blind, gasping ferocity. Tooth and nail, frothing mad with fanaticism and ancient feuds, the tribesmen rent and slew and died. Wild hair flying, the naked Kushites ran howling into the fray.
It seemed to Conan that his sweat-blinded eyes looked down into a rising ocean of steel that seethed and eddied, filling the valley from ridge to ridge. The fight was at a bloody deadlock. The hillmen held the ridges, and the mercenaries, gripping their dipping pikes, bracing their feet in the bloody earth, held the Pass. Superior position and armor for a space balanced the advantage of overwhelming numbers. But it could not endure. Wave after wave of glaring faces and flashing spears surged up the slope, the asshuri filling the gaps in the Stygian ranks.
