Ethiopia Defeats Adal’s Army at Wayna Daga

On 21 February 1543, imperial Ethiopian troops and an allied company of Portuguese musketeers faced the army of the Adal Sultanate at Wayna Daga, near Lake Tana. Led by the young Emperor Gelawdewos, the combined Christian forces engaged the soldiers of Imam Ahmad ibn Ibrahim al-Ghazi, whose forces had spent over a decade overrunning the Ethiopian interior. During the confrontation, Ahmad was struck down by gunfire. Early accounts present competing claims regarding who fired the fatal shot, attributing it either to a musketeer named Joao de Castilho or to Pero de Liao, an attendant of the late Portuguese commander Cristovao da Gama. A cavalry commander named Azmach Calite subsequently beheaded the fallen leader. The death of the Imam fractured his army, prompting an immediate Adalite retreat and bringing an end to the conquest.

The clash at Wayna Daga marked the conclusion of a devastating war that had erupted in the late 1520s. Following early border incursions, Ahmad's forces routed the army of Emperor Lebna Dengel at Shimbra Kure in 1529, relying on disciplined cavalry to outmaneuver the imperial ranks. Subsequent victories in 1531 at Antukyah and Ayfars cleared the way into the highlands, allowing the Adal forces to occupy the capital of Barara. Lebna Dengel spent his remaining years retreating through his realm until his death in 1540 at Debre Damo. The Adalite forces captured and destroyed prominent religious centers across the highlands, including the historic church of Our Lady Mary of Zion in Aksum and the burial site of several rulers at Atronsa Maryam.
