Meanwhile Hakim succeeded in raising reinforcements of 4,000 horsemen, which he tried to send across the river to Fadl. Abu Raqwa heard of this and determined to intercept them, setting out so quickly that Mahdi was unable to send a message to Fadl until he was already on the way. When the message reached Fadl it was too late, he could no longer get into a position to protect the new force from the fierce onset of the Berbers, and about a thousand of them were slain. The news of this misfortune, which Fadl contrived to conceal from his men for a time, caused great alarm in the city: the people were seized with panic, they feared an immediate assault, they were too much alarmed to remain in their houses and camped for the night in the streets.
Even yet the way to the river was not clear, for a considerable force remained ready to attack the Berbers if they tried to get down to the ford, and Abu Raqwa found it impossible to get to grips with them. So the Berbers were moved nearer and took up their position before the pyramids. Fadl followed at a distance. Then Abu Raqwa thought that he could force an engagement by leading him into an ambush. He passed on, therefore, towards the Fayyum, and at a place called Sabkha stationed a body of men in concealment and sent another company back towards Fadl. This body made a perfunctory attack and then turned to flight so as to draw the pursuers to the place of ambush. Unfortunately the whole plan had not been clearly explained to the men beforehand, and when those in ambush saw the others in flight they thought there had been a real defeat and, coming out of concealment, joined their retreat. This change in the arranged programme threw Abu Raqwa’s men into confusion, and Fadl profiting by the disorder fell upon them and inflicted a severe defeat. This took place on the 3rd of Dhu l-Hijja in 396. As a result Fadl was able to send to Cairo 6,000 heads of enemy slain and 100 prisoners.
This severe engagement was decisive, although Abu Raqwa himself escaped and fled, first to Upper Egypt, then to Nubia. Here he went to Hisnaljebel where the Nubian king lay ill, and pretended to be an ambassador sent by the Khalif Hakim. Owing to the king’s illness he was not able to see him and thus, ostensibly waiting for an interview, he was able to live for some time in security. Fadl had followed close behind to the Nubian frontier and managed to find out where he was. As soon as he knew this he sent a messenger to the governor of the palace informing him of the facts, and the governor had Abu Raqwa kept under close observation. In due course the king died and his son ordered the fugitive to be conducted across the frontier, and so he was taken across and conducted to Fadl’s camp. The Fatimid general received him with every courtesy and, fully supposing that Fadl’s conduct represented the attitude of the Khalif the prisoner, as he was in spite of polite treatment, wrote a letter to al-Hakim appealing to his generosity and begging that he might be pardoned for his rebellion with protestations of penitence.
