But now, with a deafening, vibrating roar the Ba-gcatya, massing suddenly, hurl fully one-half of their force upon the point directed by Lutali. They surge up the slope in one dense charge of lightning swiftness. Bullets are hailed upon them. They waver not. The hands of the defenders are skinned and blistered by contact with the breeches of their own rifles, so hot have these become through quick firing, and still the firing is not quick enough. Stumbling, leaping, flying over the defences they come--a great cloud of dark, grim faces, and bared teeth, and protruding eyeballs. They spring upon the defences, then over them. The whole might of the redoubtable foe is pouring into the natural fortress. [Illustration: STUMBLING, LEAPING, FLYING OVER THE DEFENCES THEY COME.] Now ensues a scene the like of which might be paralleled, but hardly surpassed, by some lurid drama of hell. In jarring shock they meet, those within and those, till now, without--the savage legionaries of "The Spider," and the no less savage and equally determined slave-hunters. The Wangoni, seeing their chance, have sprung forward to meet and roll back the assailants. But they themselves are beaten down by the broad shields, ripped with the terrible stabbing spears of the ferocious Ba-gcatya, now maddened to assuage their blood-thirst, and whose crushing might, now pouring over in countless numbers, this handful shall never hope to resist. The chief, Mashumbwe, is speared and ripped. The struggle is fierce and hand-to-hand, but short. The Wangoni, now a sorry remnant, are rolled back upon their allies. Of these not a man but knows that the day is lost, that flight is impossible; that if the other half of the Ba-gcatya host has not swarmed over to take them on the rear, it is only because it is waiting to receive on its spear points all who flee. But there is no thought of flight. With all their indifference to human suffering, with all their brutality, their savagery, the slavers are as brave as any. They are indeed men picked for their desperate courage, and now, standing back to back, they begin to render the victory of the Ba-gcatya a dearly bought one indeed. The war-shout no longer rends the air. There is a grim, fell silence in this hand-to-hand conflict, broken only by the snake-like hiss of the Ba-gcatya as an enemy goes down, by the slap and shock of shield meeting clubbed gun or stabbing knife, by the gasps of the combatants. The cloud of powder smoke hanging overhead partially veils the sun, which glowers, a blood-red ball, through this gloomy shroud. The whole space within the rock-circle is a very charnel-pit of corpses, among which the combatants stagger--victorious Ba-gcatya and vanquished slave-hunters alike--stagger and slip on a foothold of oozy gore; stab, and strike, and fall in their turn.
