Hugh Clapperton (1788–1827) was a former naval officer who was determined to explore the course of the River Niger. In 1822 he set out on an expedition to trace the river by approaching it through North Africa, though this proved unsuccessful. Three years later, Clapperton tried again, with plans to start in West Africa, and the young explorer Richard Lander (1804–1834) joined his party. They arrived in Badagry (in present-day Nigeria) and eventually crossed the Niger at Bussa, before reaching Sokoto (in north-west Nigeria), where Clapperton died from an attack of dysentery. Lander returned to England and published this two-volume account of the journey in 1830. Volume 2 describes the death of Clapperton and Lander's eventual return to England, after a series of events including a near-drowning and an offer of marriage to the daughter of a Yoruba king.
