Boo Khaloom having despatched his affairs in Bornou, wished to turn his journey to some farther account, and proposed an expedition into the more wealthy and commercial region of Houssa or Soudan, but the eager wishes of his follower pointed to a different object. They called upon him to lead them into the mountains of Mandara, in the south, to attack a village of the Kerdies or unbelievers, and carry off the people as slaves to Fezzan. He long stood out against this nefarious proposal, but the sheik who also had his own views, took part against him; even his own brother joined the malcontents, and at length there appeared no other mode in which he could return with equal credit and profit. Influenced by these inducements, he suffered his better judgement to be overpowered, and determined to conduct his troops upon this perilous and guilty excursion. Major Denham allowed his zeal for discovery to overcome other considerations, and contrived, notwithstanding the prohibition of the sheik, to be one of the party. They were accompanied by Barca Gana, the principal general, a negro of huge strength and great courage, along with other warriors, and a large troop of Bournouse cavalry. These last are a fine military body in point of external appearance. Their persons are covered with iron plate and mail, and they manage with surprising dexterity their little active steeds, which are also supplied with defensive armour. They have one fault only, but it is a serious one, they cannot stand the shock of an enemy. While the contest continues doubtful, they hover round as spectators, ready, should the tide turn against them, to spur on their coursers to a rapid flight; but if they see their friends victorious, and the enemy turning their backs, they come forward and display no small vigour in pursuit and plunder.
