''After conquering Harar in 1887, Ethiopian forces under the command of Ras Makonnen started coercing the Issa, Gadabursi, Habr Awal and the Somalis of Haud and Ogaden. The Ethiopians opened a post in 1891 at Bio-Kaboba among the Gadabursi Somalis who on paper lived under the British protection. The frequency and intensity of Ethiopian raids had increased so much that the India Office complained to the Foreign Office in early 1893 about ''the oppressive proceedings of the Abyssinians'' in regard to the levy of a daily tribute of sheep on the Yunas Jibril section of the Jibril Abokr Somalis and also of the repeated devastation of the Ogaden country. Moreover towards the south the Ethiopians had penetrated had penetrated the Juba River and Lugh in the north they claimed authority over the Issa.''
