British-Egyptian expeditions (1885–1889) Ethiopian campaigns (1885–1889) Italian campaigns (1890–1894) British-Egyptian reconquest (1896–1899) The Battle of Umm Diwaykarat on 25 November 1899 marked the final defeat of the Mahdist State in Sudan, when Anglo-Egyptian forces under the command of Lord Kitchener defeated what was left of the Mahdist armies under the command of the Abdallahi ibn Muhammad, known as the Khalifa, after the equally disastrous Battle of Omdurman a year earlier.

In October 1899 the British obtained information that the Khalifa and his forces were among his native Baggara to the west of Kusti (Kaka) in Kordofan.

Wingate marched from Kusti to the mountains of Kordofan, destroyed a Mahdist supply unit, and soon located the Khalifa's camp.

At about 5am, the Mahdists began to attack the approaching British-led forces, but were driven back by withering fire from Maxim guns.

After the defeat, the remnants of the Mahdists continued to resist for a short while under his command, but he was caught in January 1900.
