This incident occurred in the month of Jumada al-Ula in the year 10. In the month of Jumada al-Akhira, Abd al-Karim arrived with his forces in the cities of Asnar. We have mentioned that the Mahdi had twenty thousand men with him. In the early days of Shawwal, a force of the Ansar went out to attack the camp of Abd al-Karim. Abd al-Karim, with his forces, arrived in Omdurman a week after the death of the Mahdi. In the year 1310 AH, the Mahdi died. His death was a setback, and a force went out to attack the camp of Abd al-Karim. Abd al-Karim was shot in the leg, and his fighters were routed with heavy losses. The Ansar captured their camp. When the Khalifa received news of Abd al-Karim's defeat, he was enraged. The Mahdi had intended to send him to Khartoum when he summoned him from Al-Nujumi to Sinnar. In the early days of Dhu al-Qada in the year 1310 AH, the reinforcements arrived in Sinnar. The garrison in Fudan completely lost heart. The soldiers turned on their commanders, disobeyed orders, and many deserted, surrendering themselves to the enemy, whose resolve had strengthened. They returned to their original position of surrounding the city and tightening the siege. The Khalifa received news of the unity of the Ansar and their advance. He quickly sent a message requesting surrender. He sent it to Ahmad Sheikh Idris, one of the Mahdi's relatives, who was then in charge of the last prayers. Upon their arrival, the terms of peace were agreed upon between the Imam and the Dervishes, on the condition that no one would be taken.
