surprised at the unexpected resistance and were finally driven off. 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.
