The actual pursuit was abortive. Colonel Lewis, with his two battalions, followed a line of advance which led south of the zeriba, and just before reaching the river bank found and fired upon a few Dervishes retreating through the scrub. All the cavalry and the Camel Corps crossed the Atbara and plunged into the bush on the further side. But so dense and tangled was the country that after three miles of peril and perplexity they abandoned the attempt, and the routed Arabs fled unmolested. The Baggara horse had ridden off during the action, headed by the prudent Osman Digna--whose position in the zeriba was conveniently suited to such a manœuvre--and under that careful leadership suffered little loss. The rest of the army was, however, destroyed or dispersed. The fugitives fled up the Atbara river, leaving many wounded to die in the scrub, all along their line of retreat. Of the powerful force of 12,000 fighting men which Mahmud had gathered at Metemma, scarcely 4,000 reached Gedaret in safety. These survivors were added to the army of Ahmed Fedil, and thus prevented from spreading their evil tidings among the populace at Omdurman. Osman Digna, Wad Bishara, and other important Emirs whose devotion and discretion were undoubted, alone returned to the capital. As soon as the troops were re-formed, the zeriba was evacuated and the army drew up in line along the neighbouring ridge. It was then only nine o'clock, and the air was still cool and fresh. The soldiers lit fires, made some tea, and ate their rations of biscuits and meat. Then they lay down and waited for evening. Gradually, as the hours passed, the sun became powerful. There was no shade, and only a few thin, leafless bushes rose from the sand. The hours of a day, peculiarly hot, even for the country and season, dragged wearily away. The sandy ridge beat back the rays till the air above was like the breath of a furnace and the pebbly ground burned. The water in the fantasses and bottles was hot and scarce. The pool of the Atbara was foul and tainted. In spite of the devoted efforts of the few medical officers who had been allowed to accompany the force, the wounded officers and soldiers endured the greatest miseries, and it is certain that several died of their wounds who might in happier circumstances have been saved.
