the Aruwimi River to Bomili, then up the Nepoko River, across to the Duru post on the Bomokandi River, and on to the Dungu post. Much of this route was by foot, since the rivers were impassible. In 1895 Aruwimi-Uele District was divided into Aruwimi District and Uele District. Occupation At first, some of the sultans were friendly. Later, as the Belgians strengthened their grip, some such as Engwetra in 1896 rose in rebellion. Others found that by treaty their land was now French or British, or chose to move to French territory. In 1895 Jules Joseph La Haye was charged with building the Bomokandi post on the rocky right bank of the Uele River. On 10 January 1896 he met Louis-Napoléon Chaltin, who was undertaking an expedition against Bili. Chaltin and La Haye decided to move the Bomokandi post to the left bank of the river, 20' upstream. The expedition of Chaltin in 1896, assisted by 700 lancers provided by Sultan Renzi, fought the battles of Bedden and Redjaf. The Mahdists were defeated and the city of Redjaf was captured. After taking leave in Europe La Haye returned to Uele, where he was appointed district commissioner on 16 May 1897. Between 4 July 1900 and 16 January 1901 Verstraeten replaced him as district commissioner while he took leave in Europe. On his return La Haye led an expedition of 600 men against the Ababua, who had rebelled. The rebels were destroyed at the end of June 1901. On 3 July 1902 La Haye was shot and killed while sleeping in Kodia village. On 29 September 1903 the district of Uele was divided into five administrative zones: Rubber was harvested in the Uele District, and taken to the port of Bumba for storage and transport by river to Bas-Congo. A single Catholic mission was established at Gombari on the Bomokandi River. The administration responded to an epidemic of sleeping sickness that began in 1904 in the Congo Free State with measures that had been proven against cholera and plague in Europe. Between 1904 and 1914 they placed those who were infected or suspected of being infected in isolation camps or lazarets, and mapped out the zones of infection. Many of the local people in Uele District saw the health campaign as another aspect of the program of conquest and exploitation. The director of Ibembo lazaret made several proposals between 1907
