I shall say a few words of the origin of this expedition. In former days there was a Sultan, named Saloun, who divided with his brother the country which they had inherited—Saloun taking Darfur, and his brother Kordofal, which had formerly been united under one government. They swore never to undertake any intrigue one against the other, and they and their descendants remained in peace for nearly two centuries, until the time of Sultan Tyrab. Sultan Hashim, prince of Kordofal, then collected a great army, and being of an ambitious disposition, determined, it is said, to conquer Darfur. He began by sending marauding parties to the frontiers, and when his cousin wrote to him, begging to cease his molestations, answered insolently. Tyrab, therefore, resolved to make war, or, at least, chose this as a pretext. The real reason, however, was, that he had formed a plan for breaking through the law of succession laid down by Ahmed Bekr at his death. He wished to leave his throne to Izhak, the Kaliph, and resolved to send the sons and grandsons of Ahmed Bekr, and of the great people, into battle, that they might be killed, and so that there should be nobody to oppose his designs. His secret, however, was discovered, and, indeed, his whole plan subsequently failed, by the death of his son, Izhak, who was killed in battle, as will be seen. At the news of the approach of Tyrab, Hashim fled away with his suite and family, and took refuge in Sennaar, so that Kordofal was conquered with ease. The Sultan ransacked the country, and reduced the people to silence, and remained there until the next year, when his troops and his followers loudly demanded to be allowed to return to Darfur. He, however, pretended that Hashim was about to return, and that it was necessary to remain to resist him. Soon, however, the disgust of the army increased, and secret councils began to be held. At one of these, the Vizier, Ali Wad Bargou, whose daughter Tyrab had married, said boldly,—“What will you give me if I kill the Sultan? I will get rid of him, and you shall put in his place whom you please.” Those whose children Tyrab had taken out to expose them to the danger of being killed promised him great wealth if he succeeded, and it was agreed that the roll of a drum should give the signal of assistance.
