On the road to Borno, Rabih made prisoner the sultan of Karnak Logone, whose capital promptly opened its doors to his host. "Shehu" Ashimi of Borno sent 15,000 men to confront Rabih; the latter routed them in May or September 1893 first at Am Hobbio (south of Dekoa) and then at Legaroua with only 2,000 horse. Ashimi fled north of the Komadougou Yobe from where he may have tried to negotiate with Rabih; but he was assassinated at the instigation of his nephew Kyari, who then became "shehu" and decided to fight Rabih. Rabih met Kyari at Gashegar, a two days' walk from Kukawa, the capital of Borno; Kiyari defeated Rabih and captured his camp. The following day Rabih gathered his forces, and ordered 100 lashes be given to all his bannermen, including his own favored son Fadlallah. Only Boubakar, who had fought bravely, was spared. Then he ordered a victorious counter-offensive; Kyari, who had refused to flee, was captured and beheaded. As for the capital city, Kukawa, it was plundered and razed to the ground.
