But though the Arab fusillade was almost innocuous, it harassed the troops, keeping them on the alert all night. And when, with the first streaks of dawn, the dreary march began, all traces of the foe had disappeared. All the morning dragged along, till fatigue and the heat of the sun compelled the mid-day halt. Then forward again till dark; and no wells reached! Hardly a drop of water left for each man! Several had dropped and died in the course of that day’s march, and several horses. The bugle bands, which had been so cheery in the start, were silent now; the poor fellows were too parched to blow their instruments. Even the tam-tams were silent. Not that either would have been prudent, for though, doubtless, they were never lost sight of by the enemy’s scouts, there was no advantage in publishing their whereabouts.

Harry was on outpost duty that night, and when the firing was renewed, which happened soon after dark (though no enemy had been sighted all day), he, not being hard pressed, would not withdraw his men. The stars were very bright, and objects were distinguishable at about thirty yards distance; perhaps further by Harry, who was particularly clear of vision, that being the reason, possibly, of his fine shooting. The Arabs got closer to the rocks, amongst which the outpost was situated, with sentries at intervals connecting it with the square. Harry felt savage with thirst, fatigue, and this aggravating annoyance, and was strongly tempted to try and make an example. He took a rifle from one of his men, and began stalking carefully in the direction of the flashes; not directly towards them, of course, which would have been trying to meet the bullets, but on the flank.

Crouching down under a sand ridge, he got pretty close, crawled a little nearer on his hands and knees, and peered forwards. There was a flash and a report quite near to him, and then Harry could plainly distinguish the man kneeling up, withdrawing the old cartridge from his Remington. He levelled his rifle, but could not see the fore-sight, so as to align it with the object. For a moment he was nonplussed, but suddenly remembered having read of a dodge for night shooting, and resolved to try it.

He had in his pocket a small box of matches, and, taking one of these, he broke the end off and rubbed in on the fore-sight very gently, careful not to let it explode, and succeeded in making the little projection so luminous that he could align it with the back-sight and the Arab’s body. Then he pulled the trigger, and saw the dark figure leap forward and fall prone. Saw it, indeed, but only in a fraction of a second, for he stole back to the sand ridge, slipping in another cartridge as he went.

There he lay still a minute, listening and peering. Presently a tall figure, which looked gigantic in the dim light, bounded close to him, with a gun in his left hand, and a spear in his right. He had evidently made a rush in the direction of the flash, and now stood, looking right and left for the man who had fired. Harry almost touched him as he pressed the trigger, and the savage lay at his very feet. “I’ll have his spoils any way,” thought he; so he picked up the spear and Remington, and got back to his men as fast as he could. The Arab scouts, bothered by these two shots, were probably uncertain about the movements of the troops, and thought they had shifted their ground since they had marked them down, and possibly had flanking parties who might surround them. For they withdrew to a distance, fired a few shots in the direction where Harry had been, which was quite away from the main body, and the outpost too, and then gave no more trouble for that night.

In the course of the next day the water gave out entirely, and there was not a drop in the army beyond what some few far-seeing, self-denying men, had hoarded in their gourds.

Harry had not been one of these, and when the mid-day halt came he thought he was dying, and fell down in the glare of the sun, senseless. When he returned to life he found himself under the scanty shade of a mimosa tree, supported by the strong arm of a man whose sun-burned face and flowing beard, the loose robe which he wore, and the silk scarf which surrounded his tarboosh, with the pistol and dagger thrust into a shawl round his waist, seemed to betoken a native of the country; but the kindly eyes were those of an Englishman, as were the murmured words, “Poor lad! Poor lad!” which fell on his ear. His brow was deliciously cool, and his throat less parched; and he recognised that it was the man whose wonderful journey to Merv had so enthralled him when he read of it who had now spared the water, which was life, to damp his brow and give him respite; and he was certain that it was Mr O’Donovan, the newspaper correspondent, now accompanying the army of Hicks Pasha, who had saved his life.

Howard, who came up at the moment, was almost awe-struck at the sacrifice.

“I have known one man allow his veins to be drained to supply the life-blood which might be infused into the veins of his friend; but what was that to sparing water now!” he said.

The patience and discipline of the men during this trying time were admirable; there was no grumbling, no repining against their leaders; and just fancy how the sturdy Briton would have growled!
