Jules Alexandre Milz (10 September 1861 – 1 October 1902) was a Belgian soldier who was active in exploring the northeast of the Congo Free State. He traveled extensively in Uele District, where he resolved the question of whether the Uele River was the upper portion of the Ubangi River. He was second in command of an expedition to the Nile in 1891–1892, and took over command after the leader died. Early years (1861–1888) Jules Alexandre Milz was born in Virton in Belgian Lorraine on 10 September 1861. His parents were Jacques Milz and Joséphine Philippart. He joined the 2nd Mounted Chasseurs on 20 August 1880, and was appointed second lieutenant to the 4th Lancers on 29 June 1883. He entered the service of the Congo Free State in 1888. Roget Expedition (1888–1891) On 17 June 1888 Milz left Antwerp as an officer of the Force Publique. He arrived in Boma on 25 July 1888 and was assigned to the Bangalas District, where Willem Frans Van Kerckhoven was preparing the vanguard of the Léon Roget expedition. The task was to establish entrenched camps on the Aruwimi River and Sankuru River for defense against Arab slavers. Milz left Bangala on 24 October 1888 with the column led by Francis Dhanis. The column founded posts at Umangi, Upoto and Yambuya. On 8 February 1889 the column was at the confluence of the Aruwimi with the Congo River, where the Basoko station was established, capital of the new Aruwimi-Uele District. Roget took command there on 28 July 1889. The expedition then founded the posts of Bomane, Bassoa and Yambisi. Milz was put in charge of Bomane, then of Bassoa. In April 1890 Milz and Joseph Duvivier accompanied Roget to found a post in Djabir (Bondo) on the Uele. They established the Ibembo station on the Itimbiri River, where they left Duvivier in command. Milz went on with Roget to the Go rapids, then overland to the Likati River where they founded the Ekwangatana post. They entrusted this post to an African officer. They returned to Ibembo, then went NNE towards the upper Likati and Djabir, crossing the Tinda River basin. They founded Mopocho between Ibembo and the Likati on 23 May 1890, which they also entrusted to an African officer. On 25 May 1890 they crossed the Likati and on 27 May 1890 reached the Uele River opposite Sultan Djabar's village. Sultan Djabir
