The first volley rang out, and immediately afterwards on every side of that doomed square the impact of the Touaregs' charge fell like the blow of some monstrous hammer. All night they had been gathering noiselessly in the surrounding valleys. Now they had charged with lance and sword from the surrounding crests. Three sides of the square held their ground. The fourth wavered, crumpled in like a piece of broken cardboard, and the Arabs were within the square, stabbing at the backs of the soldiers, loosing and stampeding the camels. And at once, where deep silence had reigned a minute ago, the air was torn with shrill cries and oaths and the clamour of weapons. The square was broken; but here a group of men stood back to back, and with cartridge and bayonet held its ground; there another formed; and about each gun the men fought desperately. Meanwhile the morning came, a grey, clear light spread over the desert. Tavernay himself was with one of the machine-guns. It was dragged clear of the _mêlée_ and up a slope of sand. The soldiers parted in front of it, and its charge began to sweep the Touaregs down like swathes, and to pit the sand hills like a fall of rain. About the other gun the fight still raged. "Come, my children," said Tavernay, "fight well; the Touaregs give no quarter." Followed by Stretton, he led the charge. The Touaregs gave way before their furious onslaught. The soldiers reached the gun, faced about, and firing steadily kept off the enemy while the gun was run back. As soon as that was saved the battle was over. All over the hollow, wherever the Touaregs were massed, the two guns rattled out their canister. No Arab could approach them. The sun rose over the earth, and while it was rising the Touaregs broke and fled. When it shone out in its full round, there was no one left of them in that hollow except the wounded and the dead. But the victory had been dearly bought. All about the well, lying pell-mell among the Arabs and the dead camels, were the French Legionaries, some quite still, and others writhing in pain and crying for water. Stretton drew his hand across his forehead. He was stunned and dazed. It seemed to him that years had passed, that he had grown very old. Yet there was the sun new-risen. There was a dull pain in his head. He raised his hand and drew it away wet with blood. How or when he had received the blow he was quite unaware. He stood staring stupidly about him. So very little while ago men were lying here sleeping in their cloaks, quite strong, living people; now they were lying dead or in pain; it was all incomprehensible. "Why?" he asked aloud of no one. "Now, why?"
