Ваделай: История колониального форпоста на Ниле

Wadelai was a boma at a narrow point on the Albert Nile in what is now northern Uganda. There were several shortlived colonial stations there, the first being the final chief station of Emin Pasha when Governor of Equatoria. Wadelai gives its name to a current Ugandan sub county.

Wadelai lay about in a straight line north northwest of Entebbe, and by river downstream from Butiaba (on Lake Albert), The local Ragem were a Jonam branch of the Alur people, who migrated northwest under pressure from the Lango. The Ragem were first visited by a European, Lieutenant H. Chippendall, in 1875. or Walad Lāy) was a patronymic ("son of Lai") bestowed by the Sudanese. Here for some time Emin Pasha had his headquarters, evacuating the place in December 1888. Thereafter, for some years, the district was held by the Mahdists. In 1894 the British established the Protectorate of Uganda after making treaties with regional chiefs, including the "sheikh of Wadelai". The British flag was hoisted at Wadelai, on both banks of the Nile, by Major E. R. Owen. The British built a government station at on the east bank on a hill above the Nile at a spot where the river narrows to and attains a depth of At this place was a gauge for measuring the discharge of the river. The Lado Enclave of the Congo Free State controlled the west bank from 1894 and the Belgians occupied Emin's old fort. Ewart Grogan passed through in 1899, and wrote, "A tiny lake, scarce five miles wide, smothered with weed, two insignificant hills, over one of which the Union Jack flutters on a crooked pole, some gravitation defying huts, a sad eyed Englishman, such is Wadelai". Grogan lamented that the Royal Artillery officer manning the station had to spend his time "sorting mails and retailing beads and yards of cloth", keeping him from "the really important work of inspecting the country and winning the confidence of the natives". The British government post was moved from Wadelai to Fatiko in 1906 and then Koba in 1907. At the same time the Belgian post closed as part of a general withdrawal from Lado. In 1910 the Smithsonian–Roosevelt African Expedition was allowed to hunt white rhinoceros. Theodore Roosevelt described the native settlement in 1910: "thatched huts surrounded by a fence small
fields of mealies and beans, cultivated by the women, and a few cattle and goats; big wicker work fish traps". Sleeping sickness was endemic. There remained a weather station at Wadelai; According to the 1929 Encyclopaedia Britannica, steamboats between Butiaba and Nimule were still calling at the Wadelai "native village". Archaeological surveys were made of the remains of "Fort Emin Pasha" in 1935 by A. J. Rusk and in 1963 by Merrick Posnansky and the Brathay Exploration Group. In 1972 it was scheduled as a historical cultural site. A journalist visiting the British fort site in 2008 found it deserted and overgrown.
