The Battle of Shimbra Kure ("chickpea swamp") was fought in March 1529 between the forces of Adal led by ImamAhmad ibn Ibrahim al-Ghazi, and the Ethiopian army, under Dawit II (Lebna Dengel). The army of Imam Ahmad prevailed, and were in control of the field at the end of the battle. Both sides suffered heavy casualties. Despite this success, and his desire to capture and hold the Emperor's palace at Badeqe, Imam Ahmad, in part to appease his restive men, withdrew from the highlands and did not return to directly engage the Ethiopian army for two years.
Some authorities, such as Richard Pankhurst, attribute Imam Ahmad's success to the presence amongst his followers of an elite company of matchlockmen. If this is the case, then this battle was the first time Ethiopian forces had to fight against a force armed with firearms.
