Then the line of the dusty troops and the faint blue desert sky overhead went out in rolling smoke, and the little stones on the heated ground ant the tinder-dry clumps of scrub became matters of surpassing interest, for men measured their agonised retreat and recovery by these things, counting mechanically and hewing their way back to chosen pebble and branch. There was no semblance of any concerted fighting. For aught the men knew, the enemy might be attempting all four sides of the square at once. Their business was to destroy what lay in front of them, to bayonet in the back those who passed over them, and, dying, to drag down the slayer till he could be knocked on the head by some avenging gun-butt.

Dick waited with Torpenhow and a young doctor till the stress grew unendurable. It was hopeless to attend to the wounded till the attack was repulsed, so the three moved forward gingerly towards the weakest side of the square. There was a rush from without, the short hough-hough of the stabbing spears, and a man on a horse, followed by thirty or forty others, dashed through, yelling and hacking. The right flank of the square sucked in after them, and the other sides sent help. The wounded, who knew that they had but a few hours more to live, caught at the enemy's feet and brought them down, or, staggering into a discarded rifle, fired blindly into the scuffle that raged in the centre of the square.

Dick was conscious that somebody had cut him violently across his helmet, that he had fired his revolver into a black, foam-flecked face which forthwith ceased to bear any resemblance to a face, and that Torpenhow had gone down under an Arab whom he had tried to 'collar low,' and was turning over and over with his captive, feeling for the man's eyes. The doctor jabbed at a venture with a bayonet, and a helmetless soldier fired over Dick's shoulder: the flying grains of powder stung his cheek. It was to Torpenhow that Dick turned by instinct. The representative of the Central Southern Syndicate had shaken himself clear of his enemy, and rose, wiping his thumb on his trousers. The Arab, both hands to his forehead, screamed aloud, then snatched up his spear and rushed at Torpenhow, who was panting under shelter of Dick's revolver. Dick fired twice, and the man dropped limply. His upturned face lacked one eye. The musketry-fire redoubled, but cheers mingled with it. The rush had failed and the enemy were flying. If the heart of the square were shambles, the ground beyond was a butcher's shop. Dick thrust his way forward between the maddened men. The remnant of the enemy were retiring, as the few--the very few--English cavalry rode down the laggards.

Beyond the lines of the dead, a broad blood-stained Arab spear cast aside in the retreat lay across a stump of scrub, and beyond this again the illimitable dark levels of the desert. The sun caught the steel and turned it into a red disc. Some one behind him was saying, 'Ah, get away, you brute!' Dick raised his revolver and pointed towards the desert. His eye was held by the red spash in the distance, and the clamour about him seemed to die down to a very far-away whisper, like the whisper of a level sea. There was the revolver and the red light. . . . and the voice of some one scaring something away, exactly as had fallen somewhere before,--a darkness that stung. He fired at random, and the bullet went out across the desert as he muttered, 'Spoilt my aim. There aren't any more cartridges. We shall have to run home.' He put his hand to his head and brought it away covered with blood.

'Old man, you're cut rather badly,' said Torpenhow. 'I owe you something for this business. Thanks. Stand up! I say, you can't be ill here.'

Throughout the night, when the troops were encamped by the whale-boats, a black figure danced in the strong moonlight on the sand-bar and shouted that Khartoum the accursed one was dead,--was dead,--was dead,--that two steamers were rock-staked on the Nile outside the city, and that of all their crews there remained not one; and Khartoum was dead,--was dead,--was dead!

But Torpenhow took no heed. He was watching Dick, who called aloud to the restless Nile for Maisie,--and again Maisie!?

'Behold a phenomenon,' said Torpenhow, rearranging the blanket. 'Here is a man, presumably human, who mentions the name of one woman only. And I've seen a good deal of delirium, too.--Dick, here's some fizzy drink.'

'Thank you, Maisie,' said Dick.
