The death of Mungo Park and his team took a toll on the British Government so they decided to explore through another route. In 1825, Clapperton was sent out to discover where the Niger flowed into the sea.
He traveled with three of his mates and four servants. After seven weeks that they set off; only Clapperton and Richard Lander were the only ones alive.
Others had died of malaria and dysentery. Clapperton later died in Sokoto leaving Lander to go back to England with his journals.
