Then he turned, and galloped off to fetch up reinforcements. But the need was already seen. The sudden uproar had attracted the attention of the whole army, and the Sirdar instantly grasped the situation. The moment was indeed critical. If Macdonald's brigade were overwhelmed, it might have meant a general disaster; and the Sirdar at once sent orders to Wauchope's brigade, to go, at the double, to Macdonald's aid.

Fortunately Colonel Long, who commanded the artillery, had sent three batteries with Macdonald's brigade. Collinson's brigade were far away near the river, Lewis's were themselves threatened. It was evident, at once, that no assistance could reach Macdonald in time. When Gregory reached him, the Dervishes were already approaching.

"It cannot be done," Macdonald said sternly, when Gregory delivered the message. "We must fight!"

Indeed, to retreat would have meant destruction. The fire would have been ineffective, and the thirty thousand fierce foes would have been among them. There was nothing to do but to fight.

Macdonald had marched out with the 11th Soudanese on his left, the 2nd Egyptians in the centre, and the 10th Soudanese on the right--all in line. Behind, in column, were the 9th Soudanese. The last were at once brought up into line, to face the advancing enemy.

Fortunately, the Sheik Ed Din's force was still some little distance away. The batteries took their place in the openings between the battalions, and the Maxim-Nordenfeldts were soon carrying death into the advancing foe; while the Martini-Henry, with which the black and Egyptian troops were armed, mowed them down as by a scythe. The Soudanese battalions fired, as was their custom, individually, as fast as they could load; the Egyptian battalion by steady volleys.

Still the enemy pressed on, until they were within two hundred yards of the line. The emirs and other leaders, Baggara horse and many spearmen, still held on; until they fell, a few feet only from the steady infantry. The rear ranks of the Dervishes now began to fall back, and the desperate charges of their leaders grew feebler; but Ed Din's division was now within a thousand yards. Macdonald, confident that the main attack was broken, threw back the 9th Soudanese to face it, and wheeled a couple of his batteries to support them.

The already retreating Dervishes, encouraged by the arrival of Ed Din's division, returned to the attack. The 11th Soudanese swung round, to aid the 9th in their struggle with Ed Din's troops. The charges of the Dervishes were impetuous in the extreme. Regardless of the storm of shell and bullets they rushed on, and would have thrust themselves between the 9th and 11th, had not the 2nd Egyptians, wheeling at the double, thrown themselves into the gap.

The Dervishes pressed right up to them, and bayonet and spear frequently crossed; but in a fight of this kind, discipline tells its tale. The blacks and Egyptians maintained their lines, steadily and firmly; and against these, individual effort and courage, even of the highest quality, were in vain.

The ground being now cleared, the gunboats opened with Maxim and cannon upon the rear of the Dervishes. The camel corps coming up, each man dismounted and added his fire to the turmoil; and, finally, three of Wauchope's battalions arrived, and the Lincolns, doubling to the right, opened a terrible flank fire. The Dervishes broke and fled; not, as usual, sullenly and reluctantly, but at full speed, stooping low to escape the storm of bullets that pursued them.
