The right-hand Italian column moved from Uarieu Pass on an outflanking maneuver aimed to cut off the advancing Ethiopian formations. However, they soon encountered a dry wadi used by Ethiopians as an infiltration route in their attempts get into the rear of the Italian attack.

With only one path open to them, the Ethiopians had no choice but to press forward and so they did with unstoppable courage. After heavy fighting the Italians completely smashed Degiac Bejenè's forces inside the wadi. Overwhelming Italian firepower killed most of the enemy combatants including Degiac Bejenè, his son, and many of his chieftains.
