DHANIS, FRANCIS, BARON (1861-19o9), Belgian adminis trator, born in London and educated at the Belgian Ecole Militaire, went out to the Congo in 1887, and in 1892-94 commanded an ex pedition against the slave dealers. He captured in succession the three Arab strongholds at Nyangwe, Kassongo and Kabambari. He was raised to the rank of baron, and in 1895 was made vice-gov ernor of the Congo State. In 1896 he took command of an expedi tion to the Upper Nile. His troops, largely composed of the Bate tela tribes who had only been recently enlisted, and who had been irritated by the execution of some of their chiefs for cannibalism, mutinied and murdered many of their white officers. During 1897-98 he was engaged in a life-and-death struggle with them; eventually he succeeded in breaking up the bands of mutinous sol diers. In 1899 Baron Dhanis returned to Belgium. He died on Nov. 14, i9o9.
