Khamis bin Abdullah, a bold and brave man, ever ready to stand up for the privileges of the Arabs, and their rights to pass through any countries for legitimate trade, is the man who, in Speke's 'Journal of the Discovery of the Source of the Nile,' is reported to have shot Maula, an old chief who sided with Manwa Sera during the wars of 1860; and who subsequently, after chasing his relentless enemy for five years through Ugogo and Unyamwezi as far as Ukonongo, had the satisfaction of beheading him, was now urging the Arabs to assert their rights against a chief called Mirambo of Uyoweh, in a crisis which was advancing. This Mirambo of Uyoweh, it seems, had for the last few years been in a state of chronic discontent with the policies of the neighbouring chiefs. Formerly a pagazi for an Arab, he had now assumed regal power, with the usual knack of unconscionable rascals who care not by what means they step into power. When the chief of Uyoweh died, Mirambo, who was head of a gang of robbers infesting the forests of Wilyankuru, suddenly entered Uyoweh, and constituted himself lord paramount by force. Some feats of enterprise, which he performed to the enrichment of all those who recognised his authority, established him firmly in his position. This was but a beginning; he carried war through Ugara to Ukonongo, through Usagozi to the borders of Uvinza, and after destroying the populations over three degrees of latitude, he conceived a grievance against Mkasiwa, and against the Arabs, because they would not sustain him in his ambitious projects against their ally and friend, with whom they were living in peace. The first outrage which this audacious man committed against the Arabs was the halting of an Ujiji-bound caravan, and the demand for five kegs of gunpowder, five guns, and five bales of cloth. This extraordinary demand, after expending more than a day in fierce controversy, was paid; but the Arabs, if they were surprised at the exorbitant black-mail demanded of them, were more than ever surprised when they were told to return the way they came; and that no Arab caravan should pass through his country to Ujiji except over his dead body. On the return of the unfortunate Arabs to Unyanyembe, they reported the facts to Sheikh Sayd bin Salim, the governor of the Arab colony. This old man, being averse to war, of course tried every means to induce Mirambo as of old to be satisfied with presents; but Mirambo this time was obdurate, and sternly determined on war unless the Arabs aided him in the warfare he was about to wage against old Mkasiwa, sultan of the Wanyamwezi of Unyanyembe.
