First Italo-Ethiopian War
In 1896, during the First Italo-Ethiopian War, Ras Mikael fought with Menelik and led the feared cavalry against the invading Italians at the Battle of Adwa. An Italian brigade began a fighting retreat towards the main Italian positions. However, the brigade inadvertently marched into a narrow valley where Mikael's cavalry slaughtered them while shouting "Reap! Reap!" . The remains of the brigade's commander were never found.
