The advance of the rebels against Khartoum was combined with a revolt in the eastern Sudan. Colonel Valentine Baker led an Egyptian force out of Suakin and was badly defeated by 1,000 Haddendowa warriors who declared their loyalty to the Mahdi under Osman Digna at Al-Teb with 2,225 Egyptian soldiers and 96 officers killed. Because the Egyptian troops at Suakin were repeatedly defeated, a British force was sent to Suakin under General Sir Gerald Graham, which drove the rebels away in several hard-fought actions. At Tamai on 13 March 1884, Graham was attacked by the Haddendowa (whom the British nicknamed "Fuzzy Wuzzies") whom he defeated, but in the course of the battle, the Haddendowa broke a Black Watch square, an action later celebrated in the Kipling poem "Fuzzy-Wuzzy".
