English: Land occupied by the Dervish (1915) and other colonial influences, as well as cities
The official Dervish borders were:
Northwestern, was at Jidali per the excerpt "nearest dervish post was now at Jidali" (source: MOyse-Bartlett, The King's African Rifles page 421)
western, was at Badwein per the excerpt "Badwein at the eastern extremity of the Ain Valley, and thence south-west to the southern border at a point where it is intersected by the 46th degree of longitude. It was our object to confine Dervish activities to their side of this line" (Source: Douglas Jardine, 1923, page 250)
southern official boundary was at Damot/Do'mo per excerpt "cattle shall not be permitted to pass beyond the pasturage of the wells enumerated hereafter, they are the wells ... to Damot" (source: Douglas Jardine, 1923, page 158)
