The troops bivouacked some ten miles south-west of Fashi Shoya, and then marched in bright moonlight to Nefisa, encountering only a Dervish patrol of about ten men.  At Nefisa was found the evacuated camp of Ahmed Fedil, containing a quantity of grain which he had collected from the riverain district, and, what was of more value, a sick but intelligent Dervish who stated that the Emir had just moved to Abu Aadel, five miles further on.  This information was soon confirmed by Mahmud Hussein, an Egyptian officer, who with an irregular patrol advanced boldly in reconnaissance.  The infantry needed a short rest to eat a little food, and Sir Reginald Wingate ordered Colonel Mahon to press on immediately with the whole of the mounted troops and engage the enemy, so as to prevent him retreating before an action could be forced.

Accordingly cavalry, Camel Corps, Maxims, and irregulars—­whose fleetness of foot enabled them, though not mounted, to keep pace with the rest—­ set off at their best pace:  and after them at 9.15 hurried the infantry, refreshed by a drink at the water tanks and a hasty meal.  As they advanced the scrub became denser, and all were in broken and obstructed ground when, at about ten o’clock, the sound of Maxim firing and the patter of musketry proclaimed that Mahon had come into contact.  The firing soon became more rapid, and as the infantry approached it was evident that the mounted troops were briskly engaged.  The position which they occupied was a low ridge which rose a little above the level of the plain and was comparatively bare of scrub; from this it was possible at a distance of 800 yards to overlook the Dervish encampment huddled around the water pools.  It was immediately evident that the infantry and the battery were arriving none too soon.  The Dervishes, who had hitherto contented themselves with maintaining a ragged and desultory fire from the scrub, now sallied forth into the open and delivered a most bold and determined charge upon the guns.  The intervening space was little more than 200 yards, and for a moment the attack looked as if it might succeed.  But upon the instant the IXth and XIIIth Soudanese, who had been doubled steadily for upwards of two miles, came into line, filling the gap between Mahon’s guns and dismounted Camel Corps and the irregular riflemen; and so the converging fire of the whole force was brought to bear upon the enemy—­now completely beaten and demoralised.  Two Dervishes, brothers, bound together hand and foot, perished in valiant comradeship ninety-five paces from the line of guns.  Many were slain, and the remainder fled.  The whole Egyptian line now advanced upon the encampment hard upon the tracks of the retreating enemy, who were seen emerging from the scrub on to a grassy plain more than a mile away, across which and further for a distance of five miles they were pursued by the cavalry and the Camel Corps.  Three hundred and twenty corpses were counted, and at least an equal number must have been wounded.  Ahmed Fedil and one or two of his principal Emirs escaped to the southward and to the Khalifa.  The Egyptian loss amounted to five men wounded.  The troops bivouacked in square formation, at about four o’clock, near the scene of action.
