Allen commanded one of three ships on the largely unsuccessful Niger expedition of 1841, which was organized by missionary and anti-slavery groups with the backing of the British government and was intended to promote both commerce and Christianity. The expedition was quickly crippled by illness-with the first death occurring the day they entered the Niger-and had to turn back early. Nonetheless, the account provides valuable details on the Kingdoms of southern Nigeria and the tribes and natural history of the region. Howgego, II, p. 594-95.
