The Battle of Tamai (or Tamanieh) took place on 13 March 1884 between a British force under Sir Gerald Graham and a Mahdist Sudanese army led by Osman Digna. Despite his earlier victory at El Teb, Graham realised that Osman Digna's force was far from broken and that he still enjoyed support among the local population. Accordingly, a second expedition departed from Suakin on 10 March in order to defeat the Mahdists definitively. The force was composed of the same units that had fought at El Teb: 4,500 men, with 22 guns and 6 machine guns. The Mahdists had roughly 10,000 men, most of them belonging to Osman Digna's Hadendoa tribe (known to British soldiers as "Fuzzy Wuzzies" for their unique hair). Forces The British forces involved in the battle were: Squadron from 10th Hussars Squadron from 19th Hussars 1st Battalion, The Black Watch (Royal Highlanders) 3rd Battalion, The King's Royal Rifle Corps 1st Battalion, York and Lancaster Regiment 1st Battalion, Gordon Highlanders 2nd Battalion, The Royal Irish Fusiliers Royal Marines Light Infantry Royal Navy Naval Brigade 6/1 Scottish Division Royal Artillery M/1 Royal Artillery Battle On the night of 12 March the British formed an encampment, not far from Osman Digna's positions. From around 1 o'clock until dawn, Mahdist riflemen approached the camp and opened fire, but their shooting was imprecise, and they inflicted few casualties. At dawn, the artillery was brought to bear against the Mahdist skirmishers and they were driven back. The infantry (which included the Black Watch) then formed into two infantry squares each of brigade-size and advanced. One square was commanded by Colonel Davis, with General Graham, and the other by Colonel Buller. A scouting party discovered that the main body of the Mahdist force was hidden in a nearby ravine, whereupon General Graham ordered the Black Watch to charge to clear those Mahdists out, leaving a wide gap where they had been stationed in the square. A sudden onslaught of Mahdists rushed into this gap. The Black Watch found themselves under intense attack from the Sudanese. The square was flooded with a rush of tribesmen and a brutal hand-to-hand fight resulted. The Black Watch eventually won the contest, driving the Sudanese out, and reforming their square. Finding themselves in danger of being cut off, the British units fell back in disarray but were quickly reformed in good order. The Mahdist advance was halted by
