A little of this, a futile attempt at exchanging fire, and the Nemedian bowmen began falling back in disorder. Their armor was light, their weapons no match for the Bossonian longbows. The western archers were sheltered by bushes and rocks. Moreover, the Nemedian footmen lacked something of the morale of the hors.e.m.e.n, knowing as they did that they were being used merely to clear the way for the knights.
The cross-bowmen fell back, and between their opening lines the pikemen advanced. These were largely mercenaries, and their masters had no compunction about sacrificing them. They were intended to mask the advance of the knights until the latter were within smiting distance. So while the arbalesters plied their bolts from either flank at long range, the pikemen marched into the teeth of the blast from above, and behind them the knights came on.
When the pikemen began to falter beneath the savage hail of death that whistled down the slopes among them, a trumpet blew, their companies divided to right and left, and through them the mailed knights thundered.
They ran full into a cloud of stinging death. The clothyard shafts found every crevice in their armor and the housings of the steeds. Horses scrambling up the gra.s.sy terraces reared and plunged backward, bearing their riders with them. Steel-clad forms littered the slopes. The charge wavered and ebbed back.
Back down in the valley Amalric reformed his ranks. Tarascus was fighting with drawn sword under the scarlet dragon, but it was the baron of Tor who commanded that day. Amalric swore as he glanced at the forest of lance-tips visible above and beyond the head-pieces of the Gundermen.
He had hoped his retirement would draw the knights out in a charge down the slopes after him, to be raked from either flank by his bowmen and swamped by the numbers of his hors.e.m.e.n. But they had not moved.
Camp-servants brought skins of water from the river. Knights doffed their helmets and drenched their sweating heads. The wounded on the slopes screamed vainly for water. In the upper valley, springs supplied the defenders. They did not thirst that long, hot spring day.
On the King"s Altar, beside the ancient, carven stone, Xaltotun watched the steel tide ebb and flow. On came the knights, with waving plumes and dipping lances. Through a whistling cloud of arrows they plowed to break like a thundering wave on the bristling wall of spears and shields. Axes rose and fell above the plumed helmets, spears thrust upward, bringing down horses and riders. The pride of the Gundermen was no less fierce than that of the knights. They were not spear-fodder, to be sacrificed for the glory of better men. They were the finest infantry in the world, with a tradition that made their morale unshakable. The kings of Aquilonia had long learned the worth of unbreakable infantry. They held their formation unshaken; over their gleaming ranks flowed the great lion banner, and at the tip of the wedge a giant figure in black armor roared and smote like a hurricane, with a dripping ax that split steel and bone alike.
The Nemedians fought as gallantly as their traditions of high courage demanded. But they could not break the iron wedge, and from the wooded knolls on either hand arrows raked their close-packed ranks mercilessly.
Their own bowmen were useless, their pikemen unable to climb the heights and come to grips with the Bossonians. Slowly, stubbornly, sullenly, the grim knights fell back, counting their empty saddles. Above them the Gundermen made no outcry of triumph. They closed their ranks, locking up the gaps made by the fallen. Sweat ran into their eyes from under their steel caps. They gripped their spears and waited, their fierce hearts swelling with pride that a king should fight on foot with them. Behind them the Aquilonian knights had not moved. They sat their steeds, grimly immobile.
A knight spurred a sweating horse up the hill called the King"s Altar, and glared at Xaltotun with bitter eyes.
"Amalric bids me say that it is time to use your magic, wizard," he said. "We are dying like flies down there in the valley. We cannot break their ranks."
Xaltotun seemed to expand, to grow tall and awesome and terrible.
"Return to Amalric," he said. "Tell him to re-form his ranks for a charge, but to await my signal. Before that signal is given he will see a sight that he will remember until he lies dying!"
The knight saluted as if compelled against his will, and thundered down the hill at breakneck pace.
Xaltotun stood beside the dark altar-stone and stared across the valley, at the dead and wounded men on the terraces, at the grim, blood-stained band at the head of the slopes, at the dusty, steel-clad ranks reforming in the vale below. He glanced up at the sky, and he glanced down at the slim white figure on the dark stone. And lifting a dagger inlaid with archaic hieroglyphs, he intoned an immemorial invocation:
"Set, G.o.d of darkness, scaly lord of the shadows, by the blood of a virgin and the sevenfold symbol I call to your sons below the black earth! Children of the deeps, below the red earth, under the black earth, awaken and shake your awful manes! Let the hills rock and the stones topple upon my enemies! Let the sky grow dark above them, the earth unstable beneath their feet! Let a wind from the deep black earth curl up beneath their feet, and blacken and shrivel them----"
He halted short, dagger lifted. In the tense silence the roar of the hosts rose beneath him, borne on the wind.
On the other side of the altar stood a man in a black hooded robe, whose coif shadowed pale delicate features and dark eyes calm and meditative.
"Dog of Asura!" whispered Xaltotun, his voice was like the hiss of an angered serpent. "Are you mad, that you seek your doom? Ho, Baal!
Chiron!"
"Call again, dog of Acheron!" said the other, and laughed. "Summon them loudly. They will not hear, unless your shouts reverberate in h.e.l.l."
From a thicket on the edge of the crest came a somber old woman in peasant garb, her hair flowing over her shoulders, a great gray wolf following at her heels.
"Witch, priest and wolf," muttered Xaltotun grimly, and laughed. "Fools, to pit your charlatan"s mummery against my arts! With a wave of my hand I brush you from my path!"
"Your arts are straws in the wind, dog of Python," answered the Asurian.
"Have you wondered why the Shirki did not come down in flood and trap Conan on the other bank? When I saw the lightning in the night I guessed your plan, and my spells dispersed the clouds you had summoned before they could empty their torrents. You did not even know that your rain-making wizardry had failed."
"You lie!" cried Xaltotun, but the confidence in his voice was shaken.
"I have felt the impact of a powerful sorcery against mine--but no man on earth could undo the rain-magic, once made, unless he possessed the very heart of sorcery."
"But the flood you plotted did not come to pa.s.s," answered the priest.
"Look at your allies in the valley, Pythonian! You have led them to the slaughter! They are caught in the fangs of the trap, and you cannot aid them. Look!"
He pointed. Out of the narrow gorge of the upper valley, behind the Poitanians, a horseman came flying, whirling something about his head that flashed in the sun. Recklessly he hurtled down the slopes, through the ranks of the Gundermen, who sent up a deep-throated roar and clashed their spears and shields like thunder in the hills. On the terraces between the hosts the sweat-soaked horse reared and plunged, and his wild rider yelled and brandished the thing in his hands like one demented. It was the torn remnant of a scarlet banner, and the sun struck dazzlingly on the golden scales of a serpent that writhed thereon.
"Valerius is dead!" cried Hadrathus ringingly. "A fog and a drum lured him to his doom! I gathered that fog, dog of Python, and I dispersed it!
I, with my magic which is greater than your magic!"
"What matters it?" roared Xaltotun, a terrible sight, his eyes blazing, his features convulsed. "Valerius was a fool. I do not need him. I can crush Conan without human aid!"
"Why have you delayed?" mocked Hadrathus. "Why have you allowed so many of your allies to fall pierced by arrows and spitted on spears?"
"Because blood aids great sorcery!" thundered Xaltotun, in a voice that made the rocks quiver. A lurid nimbus played about his awful head.
"Because no wizard wastes his strength thoughtlessly. Because I would conserve my powers for the great days to be, rather than employ them in a hill-country brawl. But now, by Set, I shall loose them to the uttermost! Watch, dog of Asura, false priest of an outworn G.o.d, and see a sight that shall blast your reason for evermore!"
Hadrathus threw back his head and laughed, and h.e.l.l was in his laughter.
"Look, black devil of Python!"
His hand came from under his robe holding something that flamed and burned in the sun, changing the light to a pulsing golden glow in which the flesh of Xaltotun looked like the flesh of a corpse.
Xaltotun cried out as if he had been stabbed.
"The Heart! The Heart of Ahriman!"
"Aye! The one power that is greater than your power!"
Xaltotun seemed to shrivel, to grow old. Suddenly his beard was shot with snow, his locks flecked with gray.
"The Heart!" he mumbled. "You stole it! Dog! Thief!"
"Not I! It has been on a long journey far to the southward. But now it is in my hands, and your black arts cannot stand against it. As it resurrected you, so shall it hurl you back into the night whence it drew you. You shall go down the dark road to Acheron, which is the road of silence and the night. The dark empire, unreborn, shall remain a legend and a black memory. Conan shall reign again. And the Heart of Ahriman shall go back into the cavern below the temple of Mitra, to burn as a symbol of the power of Aquilonia for a thousand years!"
Xaltotun screamed inhumanly and rushed around the altar, dagger lifted; but from somewhere--out of the sky, perhaps, or the great jewel that blazed in the hand of Hadrathus--shot a jetting beam of blinding blue light. Full against the breast of Xaltotun it flashed, and the hills re-echoed the concussion. The wizard of Acheron went down as though struck by a thunderbolt, and before he touched the ground he was fearfully altered. Beside the altar-stone lay no fresh-slain corpse, but a shriveled mummy, a brown, dry, unrecognizable carca.s.s sprawling among moldering swathings.
Somberly old Zelata looked down.
"He was not a living man," she said. "The Heart lent him a false aspect of life, that deceived even himself. I never saw him as other than a mummy."
Hadrathus bent to unbind the swooning girl on the altar, when from among the trees appeared a strange apparition--Xaltotun"s chariot drawn by the weird horses. Silently they advanced to the altar and halted, with the chariot wheel almost touching the brown withered thing on the gra.s.s.
Hadrathus lifted the body of the wizard and placed it in the chariot.
And without hesitation the uncanny steeds turned and moved off southward, down the hill. And Hadrathus and Zelata and the gray wolf watched them go--down the long road to Acheron which is beyond the ken of men.
Down in the valley Amalric had stiffened in his saddle when he saw that wild horseman curvetting and caracoling on the slopes while he brandished that blood-stained serpent-banner. Then some instinct jerked his head about, toward the hill known as the King"s Altar. And his lips parted. Every man in the valley saw it--an arching shaft of dazzling light that towered up from the summit of the hill, showering golden fire. High above the hosts it burst in a blinding blaze that momentarily paled the sun.
"That"s not Xaltotun"s signal!" roared the baron.
"No!" shouted Tarascus. "It"s a signal to the Aquilonians! Look!"
