The nature of the country and its lack of grazing and water, forced the Somalis to follow in the wake of the Galla, and about 1840 — 1850 the Ogaden and Marehan crossed the head-waters of the Juba and encountered the Galla again.
Ultimately the Galla were driven through Biskaya (the Place of Battles) to the Tana Eiver where still a dwindling remnant of the tribe is found, to be followed closely by the Somali who is now
moving Westwards to the Lorian Swamp.

Also Oromos would rather f*ck with Dirs than Darods because we are more heavt handed. Do you see Darods lose any towns or cities to hordes of Oromos
