On the 20th, the news came that Fadil was crossing the river at Dakhila, twenty miles farther to the south. He himself had crossed, and the women and children had been taken over on a raft. On the 22nd, the Darfur Sheik was sent off up the west bank, to harass the Dervishes who had already crossed. On the 24th two gunboats arrived, with two hundred more men of the 10th Soudanese, and a small detachment of the 9th.

On the following day the little force started, at five in the afternoon; and, at eleven at night, halted at a little village. At three in the morning they again advanced, and at eight o'clock came in contact with the Dervish outposts. Colonel Lewis had already learned that, instead of half the Dervish force having crossed, only one division had done so, and that he had by far the greater part of Fadil's army opposed to him.

It was a serious matter to attack some four or five thousand men, with so small a force at his disposal; for he had but half the 10th Soudanese, a handful of the 9th, and two Maxim guns. As to the Darfur irregulars, no great reliance could be placed upon them.

As the force issued from the wood through which they had been marching, they saw the river in front of them. In its midst rose a large island, a mile and a quarter long, and more than three-quarters of a mile wide. There were clumps of sand hills upon it. They had learned that the intervening stream was rapid, but not deep; while that on the other side of the island was very deep, with a precipitous bank.

It was upon this island that Fadil's force was established. The position was a strong one--the sand hills rose from an almost flat plain, a thousand yards away; and this would have to be crossed by the assailants, without any shelter whatever. The Dervishes were bound to fight their hardest, as there was no possibility of escape, if defeated.

At nine o'clock the Soudanese and irregulars lined the bank and opened fire, while the two Maxims came into action. The Dervishes replied briskly, and it was soon evident that, at so long a range, they could not be driven from their position. Several fords were found, and the irregulars, supported by a company of the 10th, crossed the river, and took up a position two hundred yards in advance, to cover the passage of the rest. These crossed with some difficulty, for the water was three and a half feet deep, and the current very strong; and they were, moreover, exposed to the fire of Fadil's riflemen, from the high cliff on the opposite bank.

Colonel Lewis, determined to turn the left flank of the Dervishes, kept along the river's edge until he reached the required position; then wheeled the battalion into line, and advanced across the bare shingle against the sand hills. Major Ferguson, with one company, was detached to attack a knoll on the right, held by two hundred Dervishes. The remaining four companies, under Colonel Mason, kept straight on towards the main position.

A very heavy fire was concentrated upon them, not only from the sand hills, but from Fadil's riflemen. The Soudanese fell fast, but held on, increasing their pace to a run; until they reached the foot of the first sandhill, where they lay down in shelter to take breath. A quarter of the force had already fallen, and their doctor, Captain Jennings, remained out in the open, binding up their wounds, although exposed to a continuous fire.

This halt was mistaken by the Dervishes, who thought that the courage of the Soudanese was exhausted; and Fadil, from the opposite bank, sounded the charge on drum and bugle; and the whole Dervish force, with banners waving and exultant shouts, poured down to annihilate their assailants.

But the Soudanese, led by Colonels Lewis and Mason, who were accompanied by Gregory, leapt to their feet, ran up the low bank behind which they were sheltering, and opened a terrible fire. The Dervishes were already close at hand, and every shot told among them. Astonished at so unlooked-for a reception, and doubtless remembering the heavy loss they had suffered at Gedareh, they speedily broke. Like dogs slipped from their leash, the black troops dashed on with triumphant shouts, driving the Dervishes from sandhill to sandhill, until the latter reached the southern end of the island.
