Engraved map showing Central Africa and the predicted routes of the Emin Pasha Relief Expedition, 1887. Emin Pasha (1840-1892), the German doctor, explorer, linguist and Governor of the Egyptian Equatorial Province had retreated to Wadelai, near Lake Albert, with 10,000 followers during the Mahdi Rising of the mid-1880's. Cut off from all communication Emin Pasha was considered lost, so the British government sent out a rescue party led by H.M. Stanley (1841-1904), which reached Emin Pasha at the end of 1888. Emin Pasha was reluctant to leave Wadelai, but Stanley persuaded him to otherwise and took him to Bagamoyo on the Indian Ocean.
