Now all that was left for Abu Anga to do was to punish the mutinous troops of El Obeid who had killed Sherif Mahmud. Wad Ibrahim was sent on this duty, and after a severe fight, in which numbers were killed on both sides, he succeeded in capturing several of the mutineers, whom he attached to his troops; but some of them escaped to the Nubas, and Wad Ibrahim proceeded in consequence to Golfan-Naïma, which he besieged, took, and reduced the inhabitants to slavery; the heads of Bishir and three other leaders were sent to Omdurman, where they were exposed for a month on the gallows as a warning to all mutinous-minded persons. By all these various actions Abu Anga had succeeded in adding considerably to the numbers of his troops, and he moreover drilled them constantly and instilled a spirit of discipline which had been hitherto unknown--thus he raised up a power which it was almost impossible to defeat. Khalifa Abdullah now sent instructions to Abu Anga to return to Omdurman in time for the Bairam festival, and at the same time he sent orders to all the inhabitants of the Gezireh and Nile Valley to collect at Omdurman for a great review. Abu Anga, as usual, complied with the order with alacrity, and making forced marches, _viâ_ Tayara, Shatt, and Om Sadik, he reached Omdurman in a very short time. Abdullah sent numbers of emirs to meet and welcome him. In Omdurman the only topic of conversation was about Abu Anga and his great army. The Khalifa himself also prepared a magnificent reception for his faithful general, in which he strove to do him all possible honour. On the night preceding the great festival, criers were sent through Omdurman announcing that any one who failed to present himself at the great review the following morning would be seriously dealt with; this order was willingly complied with, and at the foot of the hills near Kerreri were assembled enormous crowds, who waited--as the malcontents said--on the pleasure of that "slave," Abu Anga. The guns had all been drawn out in line the evening before, and the festival was ushered in by prolonged salutes. In the meantime Abu Anga had arrived at Om Sadik, where a careful inspection was made to see that no one was in possession of unlawful booty; numbers of female slaves were found, who were subsequently sent to the beit el mal. He then moved on to his camp near Omdurman, and prepared to make his formal entry the following morning.
