A Map of the Route of the Emin Pasha Relief Expedition, 1890. Detailed map of the Central portion of Africa, showing the route taken in Henry Stanley's mission to rescue the Emin Pasha expedition along the Congo River and across the Congo Free State between the Atlantic and Indian Oceans.
Description taken From Raremaps.com -The Emin Pasha Relief Expedition of 1886 to 1889, was one of the last major European expeditions into the interior of Africa in the nineteenth century, ostensibly to the relief of Emin Pasha, General Charles Gordon's besieged governor of Equatoria, threatened by Mahdist forces. The expedition was led by Henry Morton Stanley and came to be both celebrated for its ambition in crossing "darkest Africa", and notorious for the deaths of so many of its members and the disease unwittingly left in its wake.
