At length, when, in spite of his utmost efforts, he was nodding with drowsiness, his ear was suddenly caught by a slight sound beneath him. He pulled himself together, and listened intently. There was no repetition of the sound. He began to think that he had been mistaken, or that the sound had been made by some small animal scurrying along the bank. But a few seconds later he heard it again; it was like that of a small stone rolling down the rocky shelf. Now fully awake, he nudged his companions and in a whisper bade them keep quiet and listen. The Pathan passes from profound sleep to complete wakefulness in an instant. They sat erect, all their senses on the alert. For a few moments nothing was heard but the gurgling rush of the river; then with startling suddenness the three watchers were aware that men were scrambling up the slope. They sprang up. Dark shapes were dimly outlined beyond the rocks. The Pathans fired, aiming as it were at shadows. Their shots did not check the rush. In another moment, clubbing their rifles, Lawrence and they were raining blows upon a swarm of figures that seemed to spring out of the black depths beneath them. Neither Lawrence nor either of the men could afterwards give a lucid account of the confused scramble that ensued. All that they were sure about was that, if they saw a form between them and the river, they hit out at it. It soon became impossible to distinguish friend from foe. In spite of their swift and weighty strokes the enemy, whose number seemed only to increase, pressed ever more closely upon them. Lawrence had just brought the butt of his rifle down with a rattling thud upon what he hoped was a Mongol skull, when the weapon was seized, and he felt himself jerked forward. He clung to the barrel tenaciously, but in trying to hold his own in this tug-of-war he lost his footing, let go the rifle perforce, and found himself rolling, or rather jolting, down the bank. Grasping at the sharp knobs of rock, he checked his fall before he came to the water’s edge, and lay for an instant to collect himself. It was perhaps a minute since the tussle had begun.
