Once the Ethiopian army found the army of Imam Ahmad, they set up camp nearby; Emperor Gelawedewos advised against engaging the enemy right away, hoping that the 50 missing Portuguese soldiers would arrive soon as "in that country fifty Portuguese are a greater reinforcement than one thousand natives." Over the following days, each camp proceeded to harass the other with cavalry raids. The allied side had the better of the exchange, keeping their opponents from venturing from their camp for supplies, until the Imam's camp managed to kill the leading Ethiopian soldier,
Azmach (
Fitawrari) Keflo, which demoralized the Ethiopian troops. Faced with the potential desertion of his force, Galawedewos decided he could wait no longer and prepared for an assault the next day. The two forces started the main battle early the next day, with the Ethiopian-Portuguese force divided into two groups. In the front was the Portuguese with 250 Abyssinian cavalrymen and 3,500 infantry, which were led by a Portuguese
mulatto named Ayres Dias; in the rear was the Emperor
Gelawdewos with another 250 cavalrymen and all the rest of the footmen. The Adal-Ottoman force also advanced in two groups, the Imam Ahmad in person in the front, with 200 Turkish matchlockmen and 600 cavalrymen and 7,000 infantry. Those in the front attacked on both flanks; in the rear was his commander, named
Guanca Grade (
Garad) with 600 cavalrymen and 7,000 infantry, who like the front attacked heavily. The Portuguese, seeing that the Muslims were prevailing, charged them, slaying many and driving the rest back; the Abyssinians, ashamed to see them fight alone, threw themselves in so vigorously that they left a "track as they went". The Imam, seeing his men lose ground, moved up to encourage them, with his son at his side. According to Portuguese sources, it was here that the Imam was hit by a bullet to his chest which threw him from his horse, although the sources differ in how he died. According to Castanhoso, the Imam came so near to the lines that he was recognized by the Portuguese arquebusiers, who directed their combined firepower at him, and one of the arquebuses in the group fired the shot. Although he was an eyewitness to the battle, Castanhoso constantly emphasizes in his account the corporate identity of the Portuguese expedition after Gama's death: "We bore before us the banner of Holy Compassion (
Sancta Misericordia); the Preste had sought to appoint one of us Captain, but we desired none save the banner of himself to lead us, for it was not to be anticipated that we should follow another, having lost what we had lost." There is another tradition, at least as old as
João Bermudes, and repeated by every other near-contemporary source (e.g.,
Gaspar Correia, Jerónimo Lobo), that gives the credit to one João de Castilho; João charged into the Adal troops so he could fire upon Ahmad Ibrahim at point-blank range, an audacious act resulting in his death. However, another contemporary Ethiopian source, although stresses the bravery of the foreign soldiers, denies them the glory of victory. The local chronicle claims that it was actually one of
Gelawdewos’ own soldiers who killed the Imam, but it doesn't identify who that soldier was or how the Imam was killed. Soon after this, some of the Muslims attempted to flee, while others tried to stop them, resulting in their hindrance of one another. Witnessing their disorder and confusion, the Portuguese attacked and killed many of them. Simultaneously, the army of
Gelawdewos attacked the Muslim rear, leading to a devastating rout, the fleeing Muslims were pursued by the Ethiopians and Portuguese who cut them down as they ran back to their camp. The Portuguese mainly followed the Turks, as Castanhoso describes; "they could not glut their revenge", of the 200 Turks no more than 40 survived. Imam Ahmad's wife
Bati del Wambara managed to escape with the surviving Turks, 300 horsemen of her personal guard, and as much of the Imam's treasure as they could carry. The moment they left their camp, the victorious Ethiopian army poured in, slaughtering everyone they encountered except for women and children. Amongst the women were numerous Christian captives and, as Castanhoso tells the story, "some found sisters, others daughters, others their wives, and it was for them no small delight to see them delivered from captivity." ==Aftermath==
