In the rear of the line, noisy, sometimes fierce and sometimes weeping, were the women, whose skill was only a little less than that of the males and who were even more ruthless in all feeling toward the enemy. And still easily chief among these, conspicuous by her noisy and uncaring demeanor of mingled alarm and vengefulness, was the raging Moonface. She rushed up close beside her husband's defending group and still hurled stones and hurled them most effectively. They went as if from a catapult, and more than one bone or head was broken that day by those missiles from the arm of this squat savage wife and mother. But the men below were outnumbering and brave, and now, maddened by different emotions, the lust of conquest, the murderous anger over slain companions and, underlying all, the thought of ownership of this fair and warm and safe place of home, were resolute in their attack. They had faith in their leader, Boarface, and expected confidently every moment an onslaught to aid them from above. And so they came up the watery slope, one pressing blood-thirstily behind the other with an earnestness none but men as strong and well equipped and as brave or braver could hope to withstand. The closing struggle was desperate.

Hilltop stood to the front, between two rocks some few yards apart, over which bubbled the shallow creek, and between which was the main upward entrance to the valley. He stood upon a rock almost as flat as if some expert engineer of ages later had planed its surface and then adjusted it to a level, leaving the shallow waters tumbling all about it. The rock out-jutted somewhat on the slope and there must necessarily be some little climb to face the aged defender. On either side was a stretch of down-running, gradually-sloping waterfall, full of great boulders, embarrassing any straight rush of a group together, but, between and upward, sprang swart men, and facing them on either side of old Hilltop beyond the rocks were the remainder of the mass of cave men upon whom he depended for making good the defense of the whole barrier. Beside him, in the center of the battle, were the two creatures in the world upon whom he could most depend, his stalwart and splendid sons, Strong-Arm and Branch. With them, as gallant if not as strong as his great brother, stood braced the eager Bark. They were ready, these young men, but, as it chanced, there could be, at the beginning of the strong clamber of the foe, only one man to first meet them. All were behind this man at the front, for the flat rock came to something like a point. He stood there, hairy and bare except for the skin about his hips, and with only an ax in his hand, but this did not matter so much as it might have done, for only axes were borne by the up-clambering assailants. The throwing of an ax was a little matter to the sharp-eyed and flexile-muscled cave men. Who could not dodge an ax was better out of the way and out of the world. A meeting such as this impending must be a matter only of close personal encounter and fencing with arm and wooden handle and flint-head of edge and weight.

There was a clash of stone together, and, one after another, strong creatures with cloven skulls toppled backward, to fall into the babbling creek, their blood helping to change its coloring. Leaping from side to side across his rock, along each edge of which the water rushed, old Hilltop met the mass of enemies, while those who passed were brained by his great sons or by those behind. But the forces were unequal and the plane in front was not steep enough nor the water deep enough to prevent something like an organized onslaught. With fearful regularity, uplifted and thrown aside occasionally in defense to avoid a stroke, the ax of Hilltop fell and there was more and more fine fighting and fine dying. On either side were men doing scarcely less stark work. Hilltop's two sons, on either side of him now, as the assailants, crowded by those behind, pressed closer, fully justified their parentage by what they did, and Bark was like a young tiger. But the onslaught was too strong. There were too many against too few. There were loud cries, a sudden impulse and, though axes rose and fell and more men tumbled backward into the water, the rock was swept upon and won and the old man stood alone amid his foes, his sons having been carried backward by the pressure of the mass. There was sullen battling on the upper level, but there was no fray so red as that where Hilltop, old as he was, swung his awful ax among the close crowding throng of enemies about him. Four fell with skulls cleanly split before a giant of the invaders got behind the gray defender of the pass. Then an ax came crashing down and old Hilltop pitched forward, dead before he fell into the cool waters of the pool below.

There was a yell of exultation from the upward-climbing Eastern cave men as they saw the most dangerous of their immediate enemies go down, but, before the echoes had come back, the sound was lost in that which came from the height above them. It was loud and threatening, but not the yell of their own kind.

There had come sweeping down the valley the victors in the fight at the Eastern end. Ab, with the lust of battle fully upon him as he heard the wild shriek of Moonface, who had seen her husband fall, was a creature as hungry for blood as any beast of all the forest, and his followers were scarce less terrible. Swift and dreadful was the encounter which followed, but the issue was not doubtful for a moment. The barrier's living defenders became as wild themselves as were these conquering allies. The fight became a massacre. Flying hopelessly up the valley, the remnant, only some twenty, of the Eastern cave men ran into the vacant big cave for refuge and there, barricaded, could keep their pursuers at bay for the time at least.

There was no immediate attack made upon the remnant of the assailants who had thus sought refuge. They were safely imprisoned, and about the cave's entrance there lay down to eat and rest a body of vengeful men of twice their number. The struggle was over, and won, but there was little happiness in the Fire Valley which had been so well defended.

Moonface, wildly fighting, had seen her husband's death. With the rush of Ab's returning force which changed the tide of battle she had been swept away, shrieking and seeking to force herself toward the rock whereon old Hilltop had so well demeaned himself. Now there emerged from one side a woman who spoke to none but who clambered down the rough waterway and waded into the little pool below the rock and stooped and lifted something from the water. It was the body of the brave old hunter of the hills. With her arms clutched about it the woman began the clamber upward again, shaking her head dumbly, when rude warriors, touched somehow, despite the coarse texture of their being, came wading in to assist her with the ghastly burden. She emerged with it upon the level and laid it gently down upon the grass, but still uttered no word until her children gathered and the weeping Lightfoot came to her and put her arms about her, and then from the uncouth creature's eyes came a flood of tears and a gasp which broke the tension, and the death wail sounded through the valley. The poor, affectionate animal was a little nearer herself again.

There were dead men lying beside the flames at the Eastern end of the valley, and these were brought by the men and tossed carelessly into the pools below where lay so many others of the slain. There were storm clouds gathering and all the valley people knew what must happen soon. The storm clouds burst; the little creek, transformed suddenly into a torrent by the fall of water from the heights above, swept the dead men away together to the river and so toward the sea. Of all the invading force there remained alive only the three who had re-leaped the flames and those imprisoned in the cave.

There was council that night between Ab and his friends and, as the easiest way of disposing of the prisoners in the cave, it was proposed to block the entrance and allow the miserable losers in battle to there starve at their leisure. But the thoughtful Old Mok took Ab aside and said:

"Why not let them live and work for us? They will do as you say. This was the place they wanted. They can stay and make us stronger."
