To this praiseworthy prince succeeded his son ʿAbd e’ Rahmán, whose death can be fixed with approximative certainty, as it is connected with the history of the neighbouring countries; for it was he against whom the sheikh Mohammed el Kánemí solicited the assistance of ʿAbd el Kerím Sabún the sultan of Wádáy, who died in the year 1815 for his having thrown off the supremacy of Bórnu, which seems to have been established during the reign of Láwení. The easy victory which the energetic and unscrupulous ruler of Wádáy, who eagerly grasped at the offer made to him, is said to have gained over the people of Bagírmi, is attributed to the consequences of a severe plague, which had swept away the greater part of the full-grown inhabitants of the country, and to the circumstance of the fácha, or general of the army, not being on good terms with his sovereign, whom he is stated to have deserted in the battle, while he himself fled with his whole detachment. Sabún, after having put to death ʿAbd e’ Rahmán, together with his favourite wife, or ghúmsu, and having carried away a considerable portion of the population, and all the riches of Bagírmi collected during the period of their power, invested the younger son of ʿAbd e’ Rahmán, of the name of Mʿallem Ngarmába Béri, with the title of king. However, as soon as Sabún had retraced his steps, ʿOthmán, the eldest son of ʿAbd e’ Rahmán, with the surname or nickname of Búgomán, who, as long as the king of Wádáy was ravaging the country, had sought refuge behind the Shárí, in the town of Búgomán (the same place the governor of which refused to receive me), returned home, overcame his younger brother, and, having put out his eyes, ascended the throne.
