At that Bigomba roared like a wounded lion, and like a wounded lion he leaped. Hurling the shield at Vulmea's head he threw all his giant body behind the arm that drove the spear at the Irishman's breast. The muscles leaped up in quivering bunches on his arm as he smote, and Wentyard cried out, unable to believe that Vulmea could avoid the lunge. But chain-lightning was slow compared to the pirate's shift. He ducked, side-stepped, and as the spear whipped past under his arm-pit, he dealt a cut that found no shield in the way. The cutlass was a blinding flicker of steel in the moonlight, ending its arc in a butchershop crunch. Bigomba fell as a tree falls and lay still. His head had been all but severed from his body.
Vulmea stepped back, panting. His great chest heaved under the tattered shirt, and sweat dripped from his face. At last he had met a man almost his match, and the strain of that terrible encounter left the tendons of his thighs quivering.
"We've got to get out of here before the rest of them come," he gasped, catching up his half of the idol's necklace. "That smaller corridor must lead to the outside, but those blacks are in it, and we haven't any torch. Let's try this door. Maybe we can get out that way."
The ancient door was a rotten mass of crumbling panels and corroded copper bands. It cracked and splintered under the impact of Vulmea's heavy shoulder, and through the apertures the pirate felt the stir of fresh air, and caught the scent of a damp river-reek. He drew back to smash again at the door, when a chorus of fierce yells brought him about snarling like a trapped wolf. Swift feet pattered up the tunnel, torches waved, and barbaric shouts re-echoed under the vaulted roof. The white men saw a mass of fierce faces and flashing spears, thrown into relief by the flaring torches, surging up the tunnel. The light of their coming streamed before them. They had heard and interpreted the sounds of combat as they hurried up the tunnel, and now they had sighted their enemies, and they burst into a run, howling like wolves.
"Break the door, quick!" cried Wentyard!
"No time now," grunted Vulmea. "They'd be on us before we could get through. We'll make our stand here."
He ran across the chamber to meet them before they could emerge from the comparatively narrow archway, and Wentyard followed him. Despair gripped the Englishman and in a spasm of futile rage he hurled the half-necklace from him. The glint of its jewels was mockery. He fought down the sick memory of those who waited for him in Englnad as he took his place at the door beside the giant pirate.
As they saw their prey at bay the howls of the oncoming blacks grew wilder. Spears were brandished among the torches—then a shriek of different timbre cut the din. The foremost blacks had almost reached the point where the corridor branched off the tunnel—and out of the corridor raced a frantic figure. It was one of the black men who had gone down it exploring. And behind him came a blood-smeared nightmare. The great serpent had turned at bay at last.
It was among the blacks before they knew what was happening. Yells of hate changed to screams of terror, and in an instant all was madness, a clustering tangle of struggling black bodies and limbs, and that great sinuous cable-like trunk writhing and whipping among them, the wedge-shaped head darting and battering. Torches were knocked against the walls, scattering sparks. One man, caught in the squirming coils, was crushed and killed almost instantly, and others were dashed to the floor or hurled with bone-splintering force against the walls by the battering-ram head, or the lashing, beam-like tail. Shot and slashed as it was, wounded mortally, the great snake clung to life with the horrible vitality of its kind, and in the blind fury of its death-throes it became an appalling engine of destruction.
Within a matter of moments the blacks who survived had broken away and were fleeing down the tunnel, screaming their fear. Half a dozen limp and broken bodies lay sprawled behind them, and the serpent, unlooping himself from these victims, swept down the tunnel after the living who fled from him. Fugitives and pursuer vanished into the darkness, from which frantic yells came back faintly.
"God!" Wentyard wiped his brow with a trembling hand. "That might have happened to us!"
"Those men who went groping down the corridor must have stumbled onto him lying in the dark," muttered Vulmea. "I guess he got tired of running. Or maybe he knew he had his death-wound and turned back to kill somebody before he died. He'll chase those blacks until either he's killed them all, or died himself. They may turn on him and spear him to death when they get into the open. Pick up your part of the necklace. I'm going to try that door again."
