By 17 August elements of the Somali Army had reached the outskirts of the strategic city of Dire Dawa. Not only was the country's second largest military airbase located here, as well as Ethiopia's crossroads into the Ogaden, but Ethiopia's rail lifeline to the Red Sea ran through this city, and if the Somalis held Dire Dawa, Ethiopia would be unable to export its crops or bring in equipment needed to continue the fight. Gebre Tareke estimates the Somalis advanced with two motorized brigades, one tank battalion and one BM battery upon the city; against them were the Ethiopian Second Militia Division, the 201 Nebelbal battalion, 781 battalion of the 78th Brigade, the 4th Mechanized Company, and a tank platoon possessing two tanks. The fighting was vicious as both sides knew what the stakes were, but after two days, despite that the Somalis had gained possession of the airport at one point, the Ethiopians had repulsed the assault, forcing the Somalis to withdraw. Henceforth, Dire Dawa was never at risk of attack.
