The whole of the Mahdi's troops were thus divided into three sections under their respective flags, and each Khalifa was in actual command of his section. The Mahdi and Sherif represented the Gellabas, who are known, in contradistinction to the Baggara, as Aulad-Belad (country people), and Aulad-Bahr (river people), because they dwell on the banks of the Nile; whilst Khalifa Abdullah and Ali Wad Helu represented the Baggara, _i.e._ the Arabs. The former of these two parties was the most capable as well as the most numerous, but, as we shall presently see, Khalifa Abdullah's party, through their leader's immense energy, gained the ascendency. Each Khalifa has numbers of emirs under him, all of whom have their different flags. These banners are quite simple and require no great labour; they are made of varied colours, and on each the Moslem creed is written, with the addition of the words: "Mohammed Ahmed el Mahdi Khalifat er Rasul" (_i.e._ "the successor of the Prophet"). This is specially directed against the Sultan of Turkey, who claims this title. Latterly flags were made to represent certain stated numbers of men; for instance, in the early days of the revolt, Abderrahman en Nejumi was designated Emir el Umara (or Emir of Emirs), because in the first instance he commanded from 2,000 to 4,000 men, and secondly, these men received a regular rate of pay, which in reality found its way into the emirs' pockets; but latterly many of the emirs command only fifty men. Each emir is assisted by several mukuddums, or under officers, and each mukuddum also has his assistant. Thus did the Mahdi organise the force which was to conquer the Sudan. He had absolutely no knowledge or system of drill, but he had men in abundance; and taking the proverb, "Nekhrib ed Dunia wa nammir el Akher" (_i.e._ "We shall destroy this and create the next world") as his motto, he thought not of sparing the lives of his men, but rather urged that by dying they should go direct to paradise. His plan, therefore, was to attack in overwhelming numbers with wild shouts, and to be regardless of all loss. Later on, at Abu Kru in the Bayuda desert, they yelled so furiously in the hope that they would alarm the English, that their commander, Nur Angara, tried to make them desist, by telling them that if they continued shouting much longer, the English would laugh at them. In spite, however, of his bold tactics, the Mahdi did not hesitate to practise every possible deception and falsehood--indeed, most of his early successes were secured by these means. At the commencement of the revolt the use of firearms was forbidden; sticks and lances formed the only arms, as it was the Mahdi's intention in this instance also to follow directly in the footsteps of the Prophet who had gained all his victories without firearms.
