Another moment, and the black mass with its waving banners and glittering weapons disappeared in a burst of fire and smoke, as the rifles spoke with a simultaneous crash. Again, and yet again, the vivid sheet of flame flashed from the side of the square; then, through the drifting fog, it was seen that the enemy were apparently changing the direction of their attack. Falling in scores before the terrible, scythe-like sweep of the volley firing, they swerved round the flank of the square and burst furiously upon the rear.

"The enemy swerved round the flank of the square, and burst furiously upon the rear."

Rapid independent firing had succeeded the regular volleys, and Jack was in the act of using his rifle, when he became conscious of a shock and swaying movement, like the commencement of a Rugby scrimmage. He turned, and saw in a moment what had happened: by sheer weight of numbers, the overpowering rush of Arabs had forced back the thin line of "Heavies," and a fierce hand-to-hand fight was in progress. What had been the interior of the square was now covered with a confused mass of struggling combatants, dimly seen through clouds of dust and smoke. Desperate fanatics hacked and stabbed with their heavy swords and long spears, while burly giants of the Guards returned equally deadly strokes with butt and sword-bayonet. Shouts, cries, and words of command mingled in a general uproar, half-drowned in the incessant din of the firing.

How long this awful contest lasted, or exactly what happened, Jack could never clearly remember. He was conscious that the rear rank had turned about, and of a vision of "Swabs" standing like a man shooting rabbits in a cover, with his rifle at his shoulder, waiting for a chance of a clear shot. Turning again to his front, he noticed the fellow on his right working frantically at his lever, and sobbing with rage and excitement over a jammed cartridge-case. "Knock it out with your cleaning-rod!" he yelled, and thrust another round into the breach of his own weapon, determined, if this were the end, to make a hard fight of the finish.

At length the pressure seemed to grow less, and then ceased; the enemy wavered, then turned and began to slowly retreat, hesitating every now and again, even in face of the withering rifle fire, as though half-minded to renew their attack. Some turned and shook their fists, while others, with the fanatic's unconquerable spirit and reckless valour, rushed back singly, only to fall long before they reached the hated foe.

Once the threatening attitude of the retiring masses raised the cry of "Close up! they're coming again!" But a well-directed volley settled the question, and the last stragglers soon disappeared behind the distant sandhills.

Cheer on cheer rose from the square, and Jack, grounding the butt of his heated weapon, joined in with a right good will, for he had fought his first battle, and his heart throbbed with the triumph of victory.

But even now the conflict was not quite over. Arab marksmen were still lurking in the broken ground, and one of them suddenly rose into view from behind a rock. Levelling his piece he fired, and Mr. Lawson, who, revolver in hand, had stepped into a gap in the ranks, fell forward on his face, the blood gushing in a crimson torrent from his mouth. At the same moment "Greek met Greek;" for "Swabs," throwing his rifle into his shoulder fired, and the Arab sharpshooter tossed up his arms and dropped out of sight behind a rock.
