1831 жылғы Эфиопиядағы Расс Марье мен Дежазмач Сабагадис арасындағы шайқас

1831 engagement in Ethiopia between Ras Marye and Dejazmach Sabagadis

The Battle of Debre Abbay, also known as the Battle of Mai Islami, was a conflict between Ras Marye of Yejju, regent of the Emperor of Ethiopia, and his rival from Tigray, Dejazmach Sabagadis of Agame. Although Ras Marye lost his life in the battle, Dejazmach Sabagadis was defeated and executed by Ras Marye's followers after surrendering. In 1830 however, Ras Marye invaded Semien, and Sabagadis broke his oath by not coming to Wube's aid, thus leaving Semien to be ravaged by conflict. Subagadis watched the battle on the border of Lasta, and subsequently did not come to the aid of Wube. In a dramatic shift of alliances, Wube sided with Marye against Sabagadis; in turn Sabagadis invaded Semien with his forces and drove Wube out of his fortresses of ‘‘Amba Tazzan’’ and ‘‘Amba Hay’’. Sabagadis recognized Wube's half brother and rival Merso Haile Maryam as the governor of Semien before his return to Tigray.

In February 1831, Wube and Ras Marye responded with a vigorous military campaign into Tigray. Marye and Wube's coalition met the forces of Sabagadis near the Tekeze river and conflict ensued. The opposing armies met on 14 February 1831 at Mai Islami near Debre Abbay (which is why this battle is also sometimes called the Battle of Mai Islami). Although Sabagadis had the superiority of a far larger number of firearms, his matchlockmen were poorly employed and failed to overcome the vaunted Oromo cavalry. The battle resulted in immense casualties, one of whom was Ras Marye. Defeated, the Dejazmach sought to escape the vengeance of Ras Marye's kinsmen by surrendering to his former ally Wube; Wube handed the Dejazmach over to his victorious allies, and the Oromo executed Sebagadis.

In the aftermath of Sabagadis's death, Tigray Province plunged into chaos. The Oromo ravaged Tigray under their new leader, Ras Dori of Yejju, but withdrew to Begemder due to his increasing illness before his death. Sabagadis' many enemies and rivals turned against his offspring. Moreover, even Sabagadis's own sons and supporters fought each other for ascendancy. Wube took advantage of the divided aristocracy, and pacified the region after a series of wars. He spared Sabagadis's sons (his wife Dinqinesh's brothers) and appointed them as tributary provincial governors in return for their submission.
