Later Edgar heard that columns of French cavalry had gone out into the desert and had driven away the bodies of Arabs that had assembled again a few miles off the Nile. They had, however, been unable to gain any advantages over them, as the Arabs had always fallen back upon their approach, and the French, finding pursuit useless, had returned to the city. Once or twice a few Arabs had been killed when the cavalry had been so closely followed by a battery of artillery that the Arabs were unaware that the French had guns with them, and had therefore contented themselves with keeping beyond carbine shot, their first intimation of their presence having been when the cavalry rode rapidly to the right and left, leaving the guns exposed.
