Mpepe favored these slave-traders, and they, as is usual with them, founded all their hopes of influence on his successful rebellion. My arrival on the scene was felt to be so much weight in the scale against their interests. A large party of Mambari had come to Linyanti when I was floundering on the prairies south of the Chobe. As the news of my being in the neighborhood reached them their countenances fell; and when some Makololo, who had assisted us to cross the river, returned with hats which I had given them, the Mambari betook themselves to precipitate flight. It is usual for visitors to ask formal permission before attempting to leave a chief, but the sight of the hats made the Mambari pack up at once. The Makololo inquired the cause of the hurry, and were told that, if I found them there, I should take all their slaves and goods from them; and, though assured by Sekeletu that I was not a robber, but a man of peace, they fled by night, while I was still sixty miles off. They went to the north, where, under the protection of Mpepe, they had erected a stockade of considerable size. There, several half-caste slave-traders, under the leadership of a native Portuguese, carried on their traffic, without reference to the chief into whose country they had unceremoniously introduced themselves; while Mpepe, feeding them with the cattle of Sekeletu, formed a plan of raising himself, by means of their fire-arms, to be the head of the Makololo. The usual course which the slave-traders adopt is to take a part in the political affairs of each tribe, and, siding with the strongest, get well paid by captures made from the weaker party. Long secret conferences were held by the slave-traders and Mpepe, and it was deemed advisable for him to strike the first blow; so he provided himself with a small battle-axe, with the intention of cutting Sekeletu down the first time they met.
