Having obtained protection in consequence of this treaty, which rendered Bagírmi as much a tributary province of Wádáy as it had been, in more ancient times, of Bórnu, ʿOthmán returned to his country, and succeeded at length in crushing his powerful and hitherto successful rival, whom he defeated in two battles,—the one fought near Kókoché, on the Báchikám, the other near the village of Ásu, on the banks of the river Shárí. The fácha, having sought and found refuge in Logón birni, fought one more battle with ʿOthmán near a place called Díndor, where a great many of the people of Wádáy who were with him are said to have fallen. But the inhabitants of Logón, fearing that Ruwéli would not be able to fight his quarrel out, and that they themselves might afterwards suffer for having given him protection, thought it more prudent to deliver him into the hands of his enemy, and succeeded in doing so by stratagem. This ambitious man is stated to have died in Wádáy, ʿOthmán having delivered him to Sabún. The restless prince of Bagírmi obtained a little tranquillity as long as Sabún lived; but Yúsuf, who succeeded the latter, dissatisfied with him, put forth another pretender, of the name of Jariñílme, and ʿOthmán had scarcely succeeded in overcoming this enemy, which he did without much trouble, when he had to fight in another quarter. For Mohammed el Kánemí, the sheikh of Bórnu (who had assisted him to reascend the throne with the sole object of regaining the ancient supremacy which Bórnu had exercised over Bagírmi), when he became aware that he had not attained his object, commenced open hostilities against him, which gave rise to a struggle carried on for a number of years with equal success on either side, but without any great result, except the ruin of the provinces near their respective frontiers. The sheikh of Bórnu, beset at the time by other difficulties, and seeing that he should be unable by himself to crush the power of Bagírmi, is then said to have called in the aid of Yúsuf Bashá, of Tripoli, who in the year 1818 sent Mústafá el Áhmar, at that time sultan of Fezzán, together with Mukní and the sheikh el Barúd, to his assistance, who, laying waste the whole north-western part of Bagírmi, and destroying its most considerable places, Babáliyá and Gáwi, carried away a great number of slaves, among whom was Agíd Músa, one of my principal informants in all that relates to Bagírmi.
