By 1919, feeling between the Darod and those Warday Galla who had been moved across the Tana River reached such a pitch that it was again necessary for the British authorities to intervene. The consequence was an undertaking by both sides, known as the Somali-Orma (Galla) agreement, which allowed the Galla who remained with the Darod on the left bank to choose finally between accepting the formal position of serfs, or of moving across the river to join their free kinsmen. Those who decided to cross the Tana were obliged to leave behind them with their Somali patrons half the cattle which they had acquired during their bondage. Under these conditions it is perhaps not surprising that few of the Warday Galla moved.
