"Is it you, Zaki?" Gregory said, scarcely able, even now, to believe that it was his faithful follower.

"It is I, master. I have been in the camp three days, and have never had a chance of getting near you, before."

"Brave fellow! good friend!" Gregory said, and then was silent.

Speech was almost inaudible, amid the roar of battle. The pipes of the Camerons could, however, be heard above the din. The men advanced steadily, in line, maintaining their excellent volley firing. The three other regiments, in close order, followed; bearing away farther to the right, so as to be able to open fire and advance. On that side the black regiments were advancing no less steadily, and the half brigade of Egyptians were as eager as any. Steadily and well under control, all pushed forward at a run; firing occasionally, but thirsting to get hand to hand with those who had desolated their land, destroyed their villages, and slain their friends.

The British were suffering, but the blacks suffered more; for the volleys of the Camerons kept down the fire of those opposed to them, better than the irregular fire of the Soudanese. The latter, however, first reached the zareba; and, regardless of thorns or of fire, dashed through it with triumphant shouts, and fell upon the defenders.

It was but a minute or two later that the Camerons reached the hedge. Formidable as it looked, it took them but a short time to tear down gaps, through which they rushed; while close behind them the Seaforths, the Lincolns, and the Warwicks were all in, bursting through the low stockade and trenches behind it, and cheering madly.

Now, from their holes and shelters, the Dervishes started up. Brave though they were, the storm that had burst upon them with such suddenness scared them, and none attempted to arrest the course of the Highlanders and red coats. Firing as they ran, the Dervishes made for the river. Many remained in their pits till the last, firing at the soldiers as they rushed past, and meeting their death at the point of the bayonet.

Hotly the troops pursued, often falling into the pits, which were half hidden by thorns and long grass. There was no attempt at regularity in these holes--nothing to show where they were. It was a wild and confused combat. The officers kept their men as well together as it was possible, on such ground; but it was sharp work, for from flank and rear, as well as in front, the shots rang out from their hidden foes, and these had to be despatched as they pushed forward.

As the troops burst through, Gregory sprang to his feet, seized a rifle that had dropped from the hands of a Dervish who had fallen close by and--shouting to Zaki "Lie still as if dead!"--joined the first line of troops. No questions were asked. Every man's attention was fixed on the work before him, and no thought was given to this white officer, who sprang from they knew not where. He had no cartridges, and the Dervishes did not carry bayonets; but, holding the rifle club-wise, he kept in the front line, falling into pits and climbing out again, engaged more than once with desperate foemen.

Striking and shouting, he fought on until the troops reached the river bank; and, having cleared all before them, poured volleys into the mass of fugitives crossing its dry bed. Other hordes were seen away to the left, similarly driven out by Lewis's Egyptians, by whom a terrible fire was kept up until the last of the fugitives disappeared in the scrub on the opposite bank, leaving the river bed thickly dotted with dead bodies; while, on the right, Macdonald's and Maxwell's blacks similarly cleared the wood.
