Absorbed in the requirements of earth, and untroubled by ghostly imaginings, officers and men slept soundly, with one eye open, as soldiers experienced in Frontier warfare learn to do; and when at last the earth, turning in its sleep, swung round towards the sun and the still air quivered with foreknowledge of morning, a sudden outcropping of life, where no life should be, amply justified the need for vigilance.

From the darkness of a ravine some distance above the camp, a shadowy mass of figures poured hurriedly, stealthily, into the valley—men of splendid physique, in loose dark draperies or sheepskin coats, carrying leathern shields and the formidable Afridi knife, bone-handled, with a two-foot blade that will halve a man's head as if it were a lemon.

By a preconcerted arrangement they divided into two parties, and keeping within the deepest patches of shadow, bore down upon the nearest pickets with a fierce, soundless rush,—the most disconcerting form of attack to sleepy sentries in the small hours, when life and courage are at their lowest ebb. But the picket sentries happened to be Sikhs; and they are ill men to tackle at close quarters or to spring on unawares.

Close upon the first determined rush came a scuffle, a smothered shout, the sharp crack of rifles in quick succession; and before the hills had flung back the volley of sound, the whole camp hummed with life from end to end, like a broken ant-heap.

A fusilade of shots rang out on all sides. Men hurried about among the tents, concentrating at the two points of attack. Here and there, amid the puffs of smoke that rose and vanished in the blue, a lifted sword or sabre gleamed like a flash of light.

A number of Afridis forced their way into the camp, lunging at every tent-rope within reach of their long knives, and in the dim light it was not easy to distinguish friend from foe. But the first sharp shock of encounter past, it became evident that the troops were getting the best of the affair; and the Afridis, whose valour is not always tempered with discretion, saw fit to beat a rapid retreat up the valley, hoping to reach the ravine before the cavalry started in pursuit.

The men in camp, meanwhile, had leisure to breathe freely, after their rough awakening; to look about and recognise one another, and exchange cheerful congratulations on the resolute stand made by the Sikhs.

"That you, Desmond?"

The Colonel's voice greeted Desmond as he emerged from his tent where his servant had been pressing on him a half-cold cup of cocoa; and the two men faced each other, bareheaded, in shirt and breeches, unmistakable stains upon their naked blades.
