"Well?" said Abd-el-Kader. And the scouts told him roughly the number of the force and the direction of the journey.
Then Abd-el-Kader turned to the Touareg chieftain.
"We will let them go further south, since southwards they are marching," he said, in his suave gentle voice. "A hundred miles more, and they will be amongst the sand dunes. Since they have cannon, the attack must be sudden. Let it be at the wells of Bir-el-Gharamo."
The Touareg chieftain rode out that day towards his hills; and, unmolested, Captain Tavernay's expedition went down to the dunes. Great waves of yellow sand, sometimes three hundred feet from crest to base, intersected the face of the desert; the winds had given to their summits the overhang of a breaking sea; they ran this way and that, as though the currents of an ocean had directed their course; they had the very look of motion; so that Stretton could not but remember the roaring combers of the cold North Sea as he gazed upon these silent and arrested copies. They made of that country a maze of intricate valleys. Led by a local guide commandeered from the last oasis, the companies of the Legion marched into the maze, and on the second day saw, as they came over a hill, just below them in a narrow hollow, a mud parapet built about the mouth of a well. This was Bir-el-Gharamo, and here they camped. Sentries were posted on the neighbouring crests; suddenly the darkness came, and overhead the stars rushed down towards the earth. There was no moon that night, nor was there any sound of danger heard. Three times Tavernay went the round of the sentries, at eight and at ten and at twelve. But at three o'clock, just as the dawn was breaking, a shot was heard. Tavernay sprang up from the ground, the alarm rang out clear from the bugle over the infinite waste, the companies of the Legion seized their piled rifles and fell into battle order with an incredible neatness and expedition. There was no confusion, no noise. The square was formed about the well--the camels were knee-haltered in the middle, the guns placed at the corners. But it was still dark. A few shots were fired on the dunes, and the sentries came running back.
"Steady," cried Captain Tavernay. "They are coming. Fire low!"
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?"
Gradually, however, custom resumed its power. There was a man hanging limp over the parapet of the well. He looked as though he had knelt down and stooped over to drink, and in that attitude had fallen asleep. But he might so easily be pushed into the well, and custom had made the preservation of wells from impurity an instinct. He removed the body and went in search of Tavernay. Tavernay was sitting propped up against a camel's saddle; the doctor was by his side, a blood-stained bandage was about his thigh. He spoke in a weak voice.
