The gates at the road to Aidhab port, fearing they would be attacked by the King of Dongola. He sent another envoy to the King of Dongola, and as a result of this investigation, Qalawun became convinced that Samamun was the unjust party. The matter became more complicated when the envoy of Sultan Qalawun to the King of the Gates was captured by Samamun's spies on his return, and they intended to kill him, but his entourage prevented him from carrying out this act, fearing that the Sultan would destroy their homes. There is no doubt that the Egyptian Mamluk envoy, upon his return to Cairo, informed Sultan Qalawun of this incident. Samamun showed his disloyalty and allegiance, and it seems he did not send the tribute and the Copts. It became incumbent upon the Sultan to send a punitive expedition against him after he had usurped power and refused all of Egypt's demands. Sultan Mansur Qalawun sent a large expedition against him in the year 670 AH/1287 AD, with the participation of the governor of Qus, Prince Izz al-Din Aidamar. He took with him individuals from some Arab tribes, such as the sons of Abu Bakr, the sons of Omar, the sons of Sharif, the sons of Shaban, the sons of al-Kanz, and Banu Hilal.

Aidamar pursued him for fifteen days without catching him. Jaris, the master of the mountain, was captured. The forces then installed Samamun's nephew on the throne and released Jaris after he declared his allegiance. Sultan Qalawun decided to keep Aidamar as a resident political officer, a high representative of the Sultan, and sent Sa'd al-Din, the nephew of King David, who was in Cairo, to be an advisor to Aidamar. The rest of the army returned to Egypt.

However, Samamun managed to regain his throne from the new king, so much so that the new king fled to Cairo. Then a third expedition was sent to him in the year 713 AH/1289 AD, and David's nephew was appointed king of the country. But Samamun retreated without engaging in combat with the Mamluk forces, but when he learned
