The migration to Omdurman. Khalid then set out for Darfur and completed its subjugation. Abu Anja marched towards Kordofan, which had been ravaged by the mountain tribes and the Jadhubiyya. He subdued some of them, while others remained independent. The western Sudan, from the borders of the Nile to the Wadi, submitted to the Mahdi.

The Fall of Omdurman and the End of the Dervish State.

Misfortune continued to befall them. The Egyptian and British governments united to bury the Dervish state, with a mixed force of British and Egyptians led by Sirdar Kitchener Pasha.

During the march from Halfa to Khartoum, the soldiers endured many hardships, most notably the Battle of Atbara, where they captured the Khalifa and about 100 of his men, along with the spoils they carried. The Sirdar then prepared to march on Omdurman.

When the Khalifa learned of this, he consulted his advisors. Some suggested fleeing, but he became angry and ordered the advisor to be beaten, saying, "I am a warrior until I die." He ordered fortifications to be built and trenches dug to withstand the enemy's fire from the Nile. This did not deter the Anglo-Egyptian forces, and Omdurman was besieged on the 2nd of September.

After three successive charges, the Khalifa was forced to flee, despairing of victory and learning that his brother Yaqub had died. The united army occupied Omdurman and raised the British and Egyptian flags. The Sirdar, upon learning of the Khalifa's flight, sent a cavalry force of 200 men with 300 bayonets in pursuit, and two gunboats by river. They returned without capturing him.

The next day, they seized the Khalifa's papers and books from his house. The Sirdar ordered the dome of the Mahdi's tomb to be demolished and his tomb to be desecrated. The Mahdi's skull was sent to the Royal College of Surgeons in London, and his other bones were scattered. They then proceeded to the house of Yaqub, the Khalifa's brother, believing the treasure to be there, but found nothing. They discovered that some of the treasure had been buried. They broke down the doors and took the gold. They then went to the house of the Mak, where they found nothing worthy of mention except a quintal of ivory.

They then went to the Khalifa's prison and released all the prisoners, numbering about 1,000 men, including government officials and soldiers.

Shortly thereafter, Sirdar Kitchener Pasha descended to Egypt and said on the Nile: "A great reward and high honor."
