The treaty between the chiefs of Abbeokuta and Captain Forbes, bound them to promote the interests of the missions, and to abolish the slave-trade. It secured to them, in turn, the protection of England. But Kosoko, of Lagos, and his confederates, resolved to prevent the introduction of Christianity, civilization and legitimate traffic into that region, to destroy Abbeokuta, and to persevere in the slave-trade. The British squadron, therefore, having found its efforts by sea, to suppress the traffic, altogether unavailing, and to save its ally, Abbeokuta, from destruction, proceeded to Lagos, December, 1851, bombarded the town, took it in possession, dethroned Kosoko, and restored Akitoye to his rightful possessions. So imminent was the danger to Abbeokuta, that Kosoko had marched at the head of a large army to destroy it, and was only diverted from his purpose by the attack upon his capital. The Portuguese slave-dealers were immediately expelled, and thus, for the moment, the slave-trade was suppressed in the Bight of Benin. But the hateful slave-trade, of which Lagos had long been the chief mart, had thoroughly engrained itself in the thoughts, habits, and hearts of the people. Taught by the slave-dealer to consider the English as natural enemies, they only awaited a suitable opportunity to renew a trade so lucrative as the capture and sale of their fellow men. Accordingly, about nine months after the expulsion of Kosoko, the Portuguese traders returned and secretly renewed the traffic in slaves. Akitoye, faithful to his treaty with the English, interposed his authority for its suppression. This led to an insurrection against him and for the restoration of Kosoko. The Portuguese supplied the insurgents with arms and ammunition; and, on the morning of August 6th, 1853, the war commenced in the streets of Lagos. The contest was kept up till night, many were killed and wounded on both sides, and the greater part of the town destroyed by fire. One of the mission houses was consumed, with nearly all of its contents; and the other would have shared the same fate, but for the protection afforded by the army of Akitoye, and by Capt. Gardner, of the British navy, then in port with his vessel. A cessation of hostilities took place for a few days, during which Kosoko entered the town and joined the rebels. The union of his forces with theirs, gave him a great superiority over Akitoye; and the missionaries, and the English consul, had no other expectation but that they would all be murdered. At this critical moment, Admiral Bruce, with a part of his squadron, appeared in sight, landed nine gun-boats, well manned, and sent a detachment of marines to protect the missionaries. This alarmed Kosoko, and, on the night following, August 13, he and his allies stole out of Lagos. Thus was the mission once more providentially delivered from destruction.[37]
