On 26 January, a battalion of roughly 550 men (mostly Italians, including 22 officers, and a few Eritrean "Askari") under Colonel Tommaso De Cristofori, were sent to reinforce the Italian garrison at Sahati. The ras learned of their departure from spies, and before they could arrive at the fortification they had erected, he attacked them at Dogali and entirely defeated them. Although the Italians were well-armed with modern rifles, cannon, and machine guns, they were outnumbered 14 to 1; they fought back against the Ethiopians and held out for hours, but they eventually exhausted all their ammunition. Nearly all were killed, except for eighty wounded men who were able to escape, unnoticed by the Ethiopians.
