Soon the moon came up in all her radiant loveliness, casting a weird and silvery glamour over the wide expanse of veldt on every side, and on the distant horizon there ever hung the blazing, star-like cone of the distant mountain-peak, for which the leaders steered. And so forward through the livelong night they pressed, faint yet pursuing, and when at dawn of day all crept into cover, and threw their wearied bodies on the ground, Amaxosa, who had been acting as whipper-in, brought up to the front the glad news that only twenty men had so far fallen by the way.
The mountain was distant now but twenty miles, and all felt relatively happy, for it was a shrewd count that three thousand naked savages, even though led by Zero, would not make very much of a figure when they found themselves between two bands, each of five hundred desperate whites, armed for the most part, with quick-firing rifles.
Grenville, Kenyon, and Amaxosa had watched and slept by turns, the last watch before night being the Zulu’s, and when his friends woke up they found the chief excessively uneasy in his mind regarding the weather, which looked to him like storm.
However, the party set out as soon as the moon began to rise, and had arrived within a mile of the mountain, and had despatched the great Zulu on ahead to scout, before the storm broke upon them.
The heavens by this time were transformed into an enormous mass of dense, black, lowering clouds, which had sunk until they almost shrouded the waning moon herself, which as yet, however, sailed along in a narrow glorious belt of glittering azure, looking far more lovely from contrast with the frowning bank of clouds which hung above her, and which stretched away in every direction ominous in their sullen death-like quietude.
The Zulu had not left the main body above five minutes when the inky-looking vault right over head was suddenly rent in twain as if some giant hand had ripped the veil of clouds, and heaven and earth seemed fairly to meet for one brief instant in a dazzling, blazing glare of lurid light, which flooded veldt and mountain, rock and river, for miles around the spot, and was instantly succeeded by an unremitting roll of thunder, which seemed to shake all nature to her utmost depths, and threaten earth with chaos worse confounded.
Hardly had the mighty echoes died away than the report of firearms could be heard, in scattered shots, away under the mountain side. The reason was evident: the Mormons had been on the alert, and the terrific blaze of lightning had, no doubt, revealed to their watchful sentinels, the ambush of the hidden savage foe. Sure enough, next minute there came the steady rolling echoes as the Winchesters opened fire in ringing volleys, upon the mass of men before them.
Speeding across the veldt, Grenville and his band endeavoured to take up a flank position where they would run no danger from the bullets of their friends, and, aided by another blazing flash, were almost within range of Zero’s troops, which were represented by a dark moving mass upon the veldt, when suddenly and without an instant’s warning, a most awful thing happened.
The moon was waning fast and the light was growing dim, when the countryside for miles and miles was all at once illuminated with a brightness vivid as the glory of the noonday sun himself. This was no passing flash of lightning; but there, right above the blazing peak itself, hung a mighty zone of dazzling, blinding fire; for one brief instant thus it stayed, then, with a mighty roar, which rent the earth and quaked the giant rocks, and dwarfed out of recognition the thunders of the sky, the volcano all at once blew up, driving its shattered fragments to the winds of heaven.
Almost at Grenville’s feet the earth yawned wildly, and where one moment before had been lovely veldt and sparkling river, there appeared only a mighty chasm, from whose abysmal depths rose fearsome sounds and pungent scalding vapours.
