It must be admitted that Raouf at once recognised the gravity of the affair, and without delay he sent a small force on Gordon's old steamer, the _Ismailia_, to bring Mahomed Ahmed to reason. This was in August 1881. By its numbers and the superior armament of the troops this expedition should have proved a complete success, and a competent commander would have strangled the Mahdist phenomenon at its birth. Unfortunately the Egyptian officers were grossly incompetent, and divided among themselves. They attempted a night attack, and as they were quite ignorant of the locality, it is not surprising that they fell into the very trap they thought to set for their opponents. In the confusion the divided Egyptian forces fired upon each other, and the Mahdists with their swords and short stabbing spears completed the rest. Of two whole companies of troops only a handful escaped by swimming to the steamer, which returned to Khartoum with the news of this defeat. Even this reverse was very far from ensuring the triumph of Mahomed Ahmed, or the downfall of the Egyptian power; and, indeed, the possession of steamers and the consequent command of the Nile navigation rendered it extremely doubtful whether he could long hold his own on the island of Abba. He thought so himself, and, gathering his forces together, marched to the western districts of Kordofan, where, at Jebel Gedir, he established his headquarters. A special reason made him select that place, for it is believed by Mahommedans that the Mahdi will first appear at Jebel Masa in North Africa, and Mahomed Ahmed had no scruple in declaring that the two places were the same. To complete the resemblance he changed with autocratic pleasure the name Jebel Gedir into Jebel Masa. During this march several attempts were made to capture him by the local garrisons, but they were all undertaken in such a half-hearted manner, and so badly carried out, that the Mahdi was never in any danger, and his reputation was raised by the failure of the Government.
