Then suddenly, from the midst of the Isigqosa army, emerged a great body of men, thousands strong, which ran swiftly, but in open order, down the slope towards the Usutu, holding their spears reversed.

At first I thought that they were charging independently, till I saw the Usutu ranks open to receive them with a shout of welcome.
"Treachery!" I said.

"Who is it ?" "Saduko, with the Amakoba and Amangwane soldiers and others.

I know them by their head-dresses," answered Maputa in a cold voice.
"Do you mean that Saduko has gone over to Cetewayo with all his following ?" I asked excitedly.
"What else, Macumazahn?
Saduko is a traitor: Umbelazi is finished," and he passed his hand swiftly across his mouth--a gesture that has only one meaning among the Zulus.
As for me, I sat down upon a stone and groaned, for now I understood everything.
Presently the Usutu raised fierce, triumphant shouts, and once again their impi, swelled with Saduko's power, began to advance up the slope.
Umbelazi, and those of the Isigqosa party who clung to him--now, I should judge, not more than eight thousand men--never stayed to wait the onslaught.

They broke! They fled in a hideous rout, crashing through the thin, left horn of the Usutu by mere weight of numbers, and passing behind us obliquely on their road to the banks of the Tugela.
