At times, indeed, the weight of the stream was almost too much for them, and swept some of them off into the deep water which ran on either side, but the strong rope of human muscles held, and they were dragged back again.  Now they were between the lip of the first walls, and the Umpondwana soldiers hurled spears at them from the banks, killing many.  But if a man was slain, or even badly wounded, his companions who held him let go, and, if needful, thrust him into the water, who could no longer serve the king.  Then he gripped the soldier who stood in front of the lost one, and the chain dragged on.

“Oh! men of the Umpondwana,” cried Sihamba, “had you but half the heart of these, who are brave, we need fear nothing from Dingaan,” and the Zulus in the stream who heard her called in answer:—­

“You are right, little chieftainess, we are brave.”

Slowly the black snake-like line pressed forward through the white foam, never heeding the storm of spears that slew continually, till the point of it was well within the third line of walls.  Then the captain, who by some chance had escaped, called an order to those behind him, and the head of the double line leapt off the ridge of rock into deep water, and swimming with their feet, but still gripping with their hands, suffered themselves to be swung round by the current towards the bank, twenty yards away.  Here some rocks jutted out, and these, after a great struggle, they were able to grasp and hold.

Then followed what Suzanne, who was watching from above, afterwards declared to be the strangest sight she had ever seen, for these men, who swung to and fro in the current, anchored, as it were, to the ridge and the bank, made of their living bodies a bridge for their fellows.  Yes, their companions ran and crawled over them, springing from shoulder to shoulder, and driving their heads beneath the water with the push of their clinging feet.  Half-drowned and almost torn in two as they were, still they held on till enough men were safe on shore to finish the fray.  For when the Umpondwana saw that the Zulus had won the bank they did not stay to kill them while they landed, as might easily have been done; no, dragging Sihamba with them, they ran into the gorge leading to the flat top of the mountain, and blocked it with great stones that were ready.  And so it came about that the Zulus won this fight, though with great loss to themselves, and cut off the Umpondwana from their main supply of water.

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.
