This incident occurred in the month of Jumada al-Ula, year [year].

And in the month of Jumada al-Akhirah, Sayyid Abd al-Karim arrived with his forces to besiege the city of Sinnar. We have already mentioned that the Mahdi had with him about twenty thousand fighters.

And in the late days of Sha'ban, news reached the Mahdi that the garrison of Sinnar, under Sayyid Abd al-Karim, had marched out against his camp and defeated him. So he sent to the army Sayyid Abd al-Rahman al-Najumi with his forces, who arrived in Omdurman a week after the death of the Mahdi.

The garrison of Sinnar received news of the death of the Mahdi. In the early days of Shawwal, year [year], the garrison was reinforced and marched out against the camp of Sayyid Abd al-Karim, attacking. Sayyid Abd al-Karim was shot in the head, and his fighters were routed with a severe defeat. The garrison captured their camp.

When the Khalifa learned of Sayyid Abd al-Karim's defeat, he sent Abd al-Rahman al-Najumi to Sinnar, as the Mahdi had intended to send him there when he summoned him from the army.

In the early days of Dhu al-Qadah, year [year], the situation in Sinnar deteriorated completely. The defenders turned on their leaders, and many of them fled and surrendered themselves to the Mahdi's forces, whose resolve had strengthened. They returned to their original position of surrounding the city's stronghold and tightening the siege.

News of Abd al-Rahman al-Najumi's advance reached the city, and it hastened to request surrender with a delegation it sent to Sayyid Ahmad Sheikh Idris, a relative of the Mahdi.

Abd al-Karim, who was at that time recovering from a gunshot wound sustained in the recent battle.

Upon its arrival, the terms of peace were agreed upon between the army and the dervishes, on the condition that no one would be taken.
