While Debre Markos and Addis Derra were being captured, other Ethiopian Patriots under "Ras" Abebe Aregai consolidated themselves around Addis Ababa in preparation for Emperor Selassie's return. In response to the rapidly advancing British and Commonwealth forces and to the general uprising of Ethiopian Patriots, the Italians in Ethiopia retreated to the mountain fortresses of Gondar, Amba Alagi, Dessie and Gimma. After negotiations prompted by Wavell, Aosta ordered the governor, Agenore Frangipani, to surrender the city to forestall a massacre of Italian civilians, as had occurred in Dire Dawa. Ashamed of not being allowed by his superior to fight to the death in the old style, the Italian governor, General Agenore Frangipani, killed himself with poison the next day.
