Denham and Clapperton, when in Africa, set out from Moorzuk under the protection of Boo Kaloom, a Fezzan chief of great distinction, who had been persuaded to join the Sultan's troops in an incursion into the Fellatah country. Unsupported by his allies, who ran away at the first difficulty, the Arab sword and gun proving to be no match for the spears and poisoned arrows of the Fellatahs, Boo Kaloom was killed with a great number of his Arabs. Denham had a narrow escape. On the return of the survivors to Fezzan, the women lamented their chief with songs of praise and mourning for many days.
