When Livinhac became Superior General of the Society of White Fathers in October 1889, John Joseph Hirth was appointed his successor.
[1] The war pitted supporters of the French Catholic missions against supporters of the British missions in Buganda, backed by a small force of Sudanese soldiers under Captain Frederick Lugard of the Indian Army.
Hirth and the White Fathers moved to the Bukoba kingdoms of Kiziba and Bugabo in 1892 with about fifty Baganda Christian converts.
The Apostolic Vicariate of Upper Nile in British territory was given to the Mill Hill Missionaries, containing the provinces of Kyaggive and Kampala Mengo.
The remaining provinces of Buganda were assigned to the Apostolic Vicariate of Northern Nyanza under the White Fathers, as well as the three Kingdoms of Unyoro, Toro and Ankole.
