Sudanese soldiers in Khartoum mutinied,[10] the Egyptian Army garrison of the Sudan was deemed unreliable and the Egyptian battalions were sent home, while the Sudanese battalions were disbanded. One hundred and forty British officers were transferred from the Egyptian army and a new Sudanese force was formed under the first Kaid Lewa Huddleston who had previously been acting Sirdar (Commander-in-Chief) of the Egyptian Army.[10] The structure of the new force of about 6,000 troops was slightly different: a little looser and more territorial, to give a better esprit de corps and sense of responsibility in each 'Corps' for its own territory. Unlike the old battalions, with anonymous numbers, the names of the four main corps were Camel Corps, Eastern Arab Corps, Western Arab Corps and Equatoria Corps.
