Spofforth was laughing now. The mental tension of the seemingly interminable wait was over.

"Two minutes more—hop it, old man," cautioned Wilmshurst. "The best of luck."

The whistles sounded. Almost immediately, as if by some uncanny means the distant gunners saw that the infantry were in motion, the strafe ceased. Overhead the seaplane still circled. The bomb-dropping part of their task completed the airmen lingered to watch the advance, and if occasion offered to assist the storming troops by means of their Lewis gun.

The natural features of the face of the plateau made the ascent a difficult one. Often the Haussas had to climb upon their comrades' shoulders, and in return help them to surmount an awkward terrace; yet everything considered the triple line was well maintained, the blacks needing no encouragement from their white officers, who, perspiring freely in every pore, were well ahead of their men.

The summit at last. Well-nigh breathless, Wilmshurst, although by no means the first, drew himself over the rocky edge of the table-land to find the ground plentifully sprinkled with barbed wire entanglements. Although this form of defence had been badly knocked about by shell-fire there was still sufficient wire, either in tension or else in snake-like coils, to offer serious impediment to the advance.

Suddenly the opening shot of a ragged, ill-aimed fusillade burst from a line of zig-zagged trenches a hundred yards from the edge of the plateau. A Haussa, in the act of assisting a comrade, sprang high in the air, and fell, his hands in his death-agony clutching at Wilmshurst's ankles.

Without knowing what trapped him the subaltern measured his length on the ground. Probably the fall saved his life, for a corporal immediately behind him was shot through the chest.

"Prone position—independent firing," shouted the major, realising that it was a forlorn hope for a few men to charge. Until a sufficient number of bayonets was on the plateau a forward movement was out of the question.

Coolly the Haussas threw themselves on the ground, taking advantage of every scrap of cover. To the accompaniment of the constant whip-like cracks of the rifles other blacks clambered upon the fairly level ground until three companies were in readiness to continue the advance.

Again the whistle sounded. The crowd of prostrate Haussas rose to their feet, yelling and shouting as they lurched forward with levelled bayonets. Men fell almost unheeded as the Waffs forced their way through the gaps in the barbed wire, and swept right and left to avoid the shell craters. By this means platoons became intermingled, while companies overlapped each other, but steadily the onward rush continued.
