The Emin Pasha Relief Expedition, led by Henry Morton Stanley, undertook to rescue Emin by going up the Congo River and then through the Ituri Forest, an extraordinarily difficult route that resulted in the loss of two-thirds of the expedition. Stanley met Emin in April 1888, and after a year spent in argument and indecision, during which Emin and Jephson were imprisoned at Dufile by troops who mutinied from August to November 1888, Emin was convinced to leave for the coast. They arrived in Bagamoyo in 1890. During celebrations Emin was injured when he stepped through a window he mistook for an opening to a balcony. Emin spent two months in a hospital recovering while Stanley left without being able to bring him back in triumph.
