But though they had won the fight they had not won the mountain. After resting a while they began the work of storming the narrow gorge that led upwards to the tableland, for this gorge was its only gate, and at first were suffered to pull down or climb over the walls which were built across it with but little resistance. Soon, however, they found out the reason of this, for when a number of them were in the gorge stones began to roll upon them from the edges of the cliffs above, crushing the life out of many, so that presently they were driven back to the head of the river. Afterwards they searched long and earnestly but could find no other path by which to attack, for there was none.
"Well," said the Zulu captain, "it seems that we must fight the fight of 'sit-down,' and since these rock-rabbits will not let us come to them we must wait till they come to us to ask for water."
So they waited for seven whole days, setting guards about the mountain in case there should be secret ways of egress of which they knew nothing.
When they reached the tableland Sihamba spoke words so bitter to her councillors and captains that some of them stopped their ears that they might hear no more, while others answered that they could do nothing against men who walked upon the boiling waters.
"Now, indeed, you can do nothing against them," Sihamba cried, "for Thirst will fight for them, and he is the best of friends. Because of your cowardice we must perish, everyone of us, and for my part I should be glad of it were it not that you have given the Lady Swallow to death also."
Then she buried her face in the ground and would say no more, even when they told her that the Zulus had been beaten back by the rocks that were rolled down upon them.
For some days the little spring gave enough water for the thousands of people who were crowded upon the mountain top, though there was none to spare for the cattle. But on the third night the poor beasts being maddened by thirst, broke out of the kraal and rushing to the spring, so trampled it with their hoofs that its waters were sealed up, and only very little could be obtained even by digging, for here the rock came near to the surface of the soil, and it would seem as though the course of the spring was turned or choked beneath it.
Then all those upon that mountain began to suffer the horrors of thirst. Soon the cattle were altogether mad and rushing to and fro in herds, bellowing furiously and goring everyone they met, or trampling them to the earth. Now the Umpondwana strove to be rid of them by driving them down the gorge, but the Zulus, guessing the trouble that the presence of these beasts was bringing upon the besieged would not suffer them to pass. Next they attempted to force them over the edge of the precipice, but when they were driven to it the oxen turned and charged through them, killing several men. After this they contented themselves with stabbing the most dangerous of the animals, and leaving the rest to rush to and fro as they would, for they did not care to kill them all lest their carcasses should breed a pestilence.
