Taking up the track of the cattle, parties were sent out to endeavour to recover them, and between twenty and thirty head, which had become foot-sore and were thus unable to proceed, were brought back in the afternoon. These were at once killed, and the expedition moved on next morning, the men carrying the meat.

The men were now very footsore, in spite of the sandals which they had from time to time made out of the skins of the slaughtered cattle. They were gaunt and haggard from nearly three months of hardship and exposure. Their faces were sunk and their limbs emaciated. Yet no thought of returning before the object of the expedition should have been accomplished occurred to them.

Three days after that on which they had discovered the desertion of the guides, they began to pass human skeletons lying on the path, the bones scattered about and broken, evidently through the agency of beasts of prey. All those that had contained marrow had been cracked, apparently by the jaws of hyenas. Late in the afternoon they reached a spot where about forty or fifty disjointed skeletons were lying indiscriminately. Kondwana noticed scattered about, a quantity of mineral similar to the specimens shown to him at Tshaka's when he received his instructions. "Ah ha!" said he, "this accounts for their not having returned."

The unfortunate copper-carriers had evidently been surprised, surrounded, and killed to a man—probably by the Balotsi. The Zulus, delighted at obtaining evidence of the bare existence of the thing they were seeking, walked about, picking up fragments of the ore, which they put into their skin wallets. It was evident that the greater part of the ore had been removed, yet every man of the expedition was able to secure a piece which he looked upon as a kind of amulet to bring him good fortune. There was a little fuel obtainable where they camped for the night, and the weary, haggard men went to sleep feeling in better spirits than for a long time past.

Just at daybreak next morning the sentries gave the alarm, and the Zulus sprang to their feet to find themselves surrounded by foes. A large Balotsi impi had been sent to intercept them.

The attack began at once, and for a time the struggle was fierce. But at close quarters one Zulu was a match for ten Balotsi, so the assailants were soon glad to retire, leaving nearly a hundred dead behind them. The Zulus lost about five or six men. It was broad daylight when the Balotsi drew off, and the Zulus could see their enemies massed round them in every direction, and outnumbering them excessively. Both parties paused for a time, each watching the other. The sun rose up over the mountains, the sky was clear as a dewdrop, and a bracing breeze swept down the valley, making music through the quivering reeds. Herds of eland, hartebeests, gnu, and other game, stood on the slopes afar off, and looked down on the dark masses of men standing still in grim silence after their desperate struggle.

Then Kondwana gave the order to retreat. There was no other course possible. Hardly any food was left, and the Balotsi were in such force as to render it impossible to cope with them successfully.

So the Zulus began to retire along the course by which they had advanced, and thus their travail entered into its final stage of long agony.

Back towards the saddle at the top of the pass through the mountain range marched Kondwana and the Zulus, the Balotsi force accompanying them at a respectful distance on each side. The Balotsi had had a severe lesson, and were not anxious to come again to close quarters. They found, moreover, that throwing the assegai was not of much avail on account of the large shields which the Zulus carried. Besides, the Zulus made a practice of picking up the assegais falling near or amongst them, and returning these, often with deadly effect, for, being physically much stronger than the Balotsi, their effective range with the assegai was correspondingly greater.
